Is It The End of Stainless Steel?

Related Steel:

Whirlpool turned a few heads last week when they announced their new White Ice finish for their deluxe kitchen appliance collection. The white, mirrored-glass, silver-accented design is notable because for the first time in at least a decade, the exterior of a major-brand, top-end appliance line isn’t strictly stainless steel.

There have been other hints that the industry is shifting away from a solely stainless design plan, like these colorful ranges. To be fair, they’ve mostly come from less-familiar European brands and niche manufacturers. (Though Whirlpool’s own Amana line did introduce a floral refrigerator finish back in 2009. We’re still waiting for it to revolutionize interior design tastes.

But even with new finishes available, is stainless still king? It isn’t going anywhere anytime soon. Almost all of the ovens that we’ve reviewed on OvenInfo.com are predominantly stainless. Almost all of the upcoming major-brand premium kitchen lines will still be stainless. Stainless is cheap to make, relatively easy to clean, and has become the standard for kitchen design—sensibilities don’t change overnight.

White Ice and other colorful finishes do seem to represent a shift in the way that we think about interior design: We’re doing it to please ourselves and create comfortable living spaces right now, rather than designing to boost resale value. Younger homeowners in particular seem to prefer the extra choices.

So what do you think? How long will stainless maintain its reign? Is color a passing fad? Does anybody really want an iOven to match their iPad? Aren’t they just tools for cooking and cleaning anyway? What colors will our robot maids come in?

Iran Increases Steel Production

The World Steel Association said in its latest report that Iran produced 1.25 million tons of crude steel last month, showing a two-percent increase as compared with June 2012.

The country also produced 7.327 million tons of steel in the first six months of 2013.

Iran produced 3.833 million tons of steel in the first three months of the current Iranian calendar year (started March 21, 2013), which was a 1.2-percent rise compared to the same period in the previous year.

Iranian steel smelters also produced 4.055 million tons of steel products in spring 2013. They produced 1.193 million tons of crude steel in the Iranian calendar month of Khordad (May 22-June 21) as well as 1.295 million tons of steel products during the month.

Iran plans to increase its steel output to more than 24 million tons by the end of the Iranian calendar year.

The country’s crude steel production reached 14.89 million tons in the previous Iranian calendar year (ended March 20, 2013).

On June 27, Iranian President Mahmoud Ahmadinejad inaugurated the Pasargad Steel Mill in the southern province of Fars.

Steel Plate Product:

According to its website, the Pasargad Steel Mill aims to produce high-quality steel products in line with the highest international standards.

Iran plans to increase its annual steel output to 55 million tons by the end of the Fifth Five-Year Development Plan (March 2010-March 2015).

Iran is reportedly the biggest steel producer in the Middle East and North Africa. The country’s main steel mills are located in Isfahan and Khuzestan provinces.

Iran’s major raw steel producers are the Mobarakeh Steel Mill, with approximately 47 percent of the market share, the Khuzestan Steel Company, with about 23 percent of the market share, the Isfahan Iron Smelting Complex, with a market share of 20 percent, and the Iran National Steel Industries Group, with approximately 10 percent of the market share.

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.
