Architects wrap buildings with Stainless Steel

With the pollen-rich landscapes of spring we discussed in our last post behind us and the sweltering days of summer beating down on our heads, the draw of cool shoreline breezes is tempting. What the casual beachgoer may not know, however, is that these waterfront locales often present challenging conditions that require special material applications to stand up to Mother Nature and ensure the longevity of coastal designs. Stainless steel plays a starring role in this success.

A popular medium in many design fields, stainless steel’s sleek finish and sharp lines appeal to both modern and contemporary sensibilities. Architects wrap buildings with it, industrial designers cloak gadgets in it, jewelry designers fashion accessories from it, and interior designers select it for kitchen sinks. Its corrosion-resistant properties also make it the best option for exterior applications in waterfront environments, compared to other metals (steel, galvanized steel, CORTEN steel, aluminum, iron, and bronze),— especially for brackish and saline waterways such as those of New York City’s coastal areas.

For our Hudson River Park Tribeca Section project, we designed a stainless steel railing at the pier’s edge, contributing to the installation’s longevity while enhancing the finish and aesthetic of this safety feature. Other cost-effective metals, like powder-coated or galvanized steel, were used for the park’s interior spaces. When designing with stainless steel, it is important that all attached metals, including connectors, fasteners, and anchors, are of the same material. Dissimilar metals in contact with stainless steel will accelerate corrosion and reduce the strength and lifespan of the product. This reaction is known as galvanic corrosion—a topic we’ll cover in a future post.

Steel Plate Product:

Stainless steel is available in a multitude of grades, each classified based on the percentages of the various alloy components present in the product. Altering the alloy content affects the metal’s characteristics, including its strength, corrosion resistance, brittleness, magnetism, etc. For example, Type 304 is the most widely used grade of the metal in landscape applications, whereas Type 420 is utilized for cutlery. Type 316 stainless steel, which has greater nickel content than Type 304, offers enhanced corrosion resistance in saline environments and is therefore typically specified for marine and waterfront landscape installations. Type 316 is slightly more expensive compared to Type 304, due to its alloy content, but its durability makes it a valuable investment. Type 316 stainless steel was used at our Hunts Point Landing project in the Bronx due to its proximity to Long Island Sound—a brackish waterway—whereas Type 304 was used at noteworthy non-marine projects including St. Louis’s Gateway Arch and New York City’s Unisphere.

Beyond the corrosion resistance and notable strength of stainless steel, the breadth of available finishes and forms is another appealing aspect of this metal for designers. It is available in multiple finishes ranging from the highly polished look often used for interior applications or jewelry, to brushed finishes that more easily camouflage fingerprints and light debris, to a bead blast—almost matte—finish. Bead blast finish works well in exterior applications, as it retains far less heat than polished surfaces—no one wants to sit on a scalding hot bench as they catch a summer breeze off the water! At our Fulton Landing Pier, a number of forms and finishes were integrated into the project’s decorative railing, including polished or blasted stainless steel pipes, plates, cables and anchors, which enhanced its aesthetic appeal.

Thanks to improved technology, stainless steel plate can be cut to almost any shape, freeing the designer from right angles, straight edges, or measured radii. Designers can provide their design drawings to fabricators who can then perfectly transform their 2D schematics into 3D forms via laser and water jet cutters. Our West Thames Park in Battery Park City incorporates stainless steel mesh and rods into a colorfully painted steel shade structure that provides dappled shade for now—until its twining vines are able to provide a dense canopy, woven throughout the overhead structure.

Appropriate material selection is integral to the success and longevity of built environments. Also crucial to the success of a landscape, yet seldom discussed, is soil. Hidden out of sight below plants, mulch, and pavement, this vital material will be addressed in our next post.

Grades 316

Stainless steel grades 316 and 316L are also known as types 1.4401 and 1.4404 respectively. Grade 316 is an austenitic grade second only to 304 in commercial importance. 316 stainless steel contains an addition of molybdenum that gives it improved corrosion resistance. This is particularly apparent for pitting and crevice corrosion in chloride environments. 316L, the low carbon version of 316 stainless steel, is immune to grain boundary carbide precipitation (sensitisation). This makes it suited to use in heavy gauge (over about 6mm) welded components.

For elevated temperature applications the high carbon variant, 316H stainless steel and the stabilised grade 316Ti stainless steel should be employed. The austenitic structure of 316 stainless steel gives excellent toughness, even at cryogenic temperatures.

Property data given in this document is typical for flat rolled products covered by ASTM A240/A240M. ASTM, EN or other standards may cover products. It is reasonable to expect specifications in these standards to be similar but not necessarily identical to those given in this datasheet.

Corrosion Resistance

SUS 316 grade has excellent corrosion resistance when exposed to a range of corrosive environments and media. It is usually regarded as “marine grade” stainless steel but is not resistant to warm sea water. Warm chloride environments can cause pitting and crevice corrosion. Grade 316 is also subject to stress corrosion cracking above around 60°C.

Heat Resistance
SUS316 has good resistance to oxidation in intermittent service to 870°C and in continuous service to 925°C. However, continuous use at 425-860°C is not recommended if corrosion resistance in water is required. In this instance 316L is recommended due to its resistance to carbide precipitation. Where high strength is required at temperatures above 500°C, grade 316H is recommended.

Fabrication

Fabrication of all stainless steels should be done only with tools dedicated to stainless steel materials. Tooling and work surfaces must be thoroughly cleaned before use. These precautions are necessary to avoid cross contamination of stainless steel by easily corroded metals that may discolour the surface of the fabricated product.

Cold Working

Grade 316 is readily brake or roll formed into a variety of parts. It is also suited to stamping, heading and drawing but post work annealing is recommended to relieve internal stresses. Cold working will increase both strength and hardness of 316 stainless steel.

Hot Working

All common hot working processes can be performed on 316 stainless steel. Hot working should be avoided below 927°C. The ideal temperature range for hot working is 1149-1260°C. Post-work annealing is recommended to ensure optimum corrosion resistance.

Heat Treatment
316 stainless steel cannot be hardened by heat treatment. Solution treatment or annealing can be done by rapid cooling after heating to 1010-1120°C.

Machinability
316 stainless steel has good machinability. Machining can be enhanced using the following rules:

  • Cutting edges must be kept sharp. Dull edges cause excess work hardening.
  • Cuts should be light but deep enough to prevent work hardening by riding on the surface of the material.
  • Chip breakers should be employed to assist in ensuring swarf remains clear of the work
  • Low thermal conductivity of austenitic alloys results in heat concentrating at the cutting edges. This means coolants and lubricants are necessary and must be used in large quantities.
Welding
Fusion welding performance for 316 stainless steel is excellent both with and without fillers. Recommended filler rods and electrodes for 316 and 316L are the same as the base metal, 316 and 316L respectively. Heavy welded sections may require post-weld annealing. Grade 316Ti may be used as an alternative to 316 in heavy section welds. Oxyacetylene welding has not been found to be successful for joining of 316 stainless steel.
Stainless Steel 316Ti
Another variation of 316 is available. This variation is 316Ti. Stainless steel grade 316Ti contains a small amount of titanium. Titanium content is typically only around 0.5%. The titanium atoms stabilise the structure of the 316 at temperatures over 800°C. This prevents carbide precipitation at the grain boundaries and protects the metal from corrosion. The main advantage of 316Ti is that it can be held at higher temperatures for a longer period without sensitisation Linkprecipitation) occurring. 316Ti retains physical and mechanical properties similar to standard grades of 316.

Characteristic

DURINOX ™ is developed mainly for the agricultural industries where corrosion and abrasion are often the major source of cost and quality problems.

Durinox™ is a registered trademark of Beyond-steel covering a range of ferritic stainless steel grades.

Durinox™ offers superior and low-cost solution to carbon steels and, in many cases, to austenitic stainless steels.

Durinox™ is developed mainly for the agricultural industries where corrosion and abrasion are often the major source of cost and quality problems. It is also often the case that many of the plants in agricultural industries were originally designed with carbon steels because of its low cost. In many cases, this proved a false
economy, since carbon steel performs poorly against corrosion and abrasion.

Durinox™ stainless steels is an excellent choice for agricultural industries as it is both chemically inert in contact with food and produce and also biologically inert which reduce the risk of micro-organism colony growth.

Durinox™ offers the following benefits compared to austenitic stainless steels and carbon steel:

  • Similar thermal expansion to carbon steel and lower compared to austenitic stainless steels, and there-
    fore it distort less when heated
  • Thermal conductivity that is much higher than austenitic stainless steels
  • High temperature oxidation resistance, they are less prone to scaling
  • Its mechanical properties are very similar to carbon steel making it easy to cut and work without the need of specialized tools. They are also less prone to spring back compared austenitic stainless steels
  • It is not prone to stress corrosion cracking
  • They can be used in temperatures to up to 600°C which is far better than carbon steel and is more than
    sufficient for most agricultural industries
