Characteristic Grades 304

Stainless steel grade 304 is the most versatile and widely used stainless steel. It is still sometimes referred to by its old name 18/8 which is derived from the nominal composition of type 304 being 18% chromium and 8% nickel. Stainless steel types 1.4301 and 1.4307 are also known as grades 304 and 304L respectively.

Stainless steel 304 is an austenitic grade that can be severely deep drawn. This property has resulted in 304 being the dominant grade used in applications like sinks and saucepans.

Stainless steel 304L is the low carbon version of 304. It is used in heavy gauge components for improved weldability. Some products such as plate and pipe may be available as “dual certified” material that meets the criteria for both 304 and 304L. 304H, a high carbon content variant, is also available for use at high 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 sold. It is reasonable to expect specifications in these standards to be similar but not necessarily identical to those given in this datasheet.

Corrosion Resistance

304 has excellent corrosion resistance in a wide variety of environments and when in contact with different corrosive media. Pitting and crevice corrosion can occur in environments containing chlorides. Stress corrosion cracking can occur at temperatures over 60°C.
 
Heat ResistanceJustify Full304 has good resistance to oxidation in intermittent service up 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 304L is recommended due to its resistance to carbide precipitation.Where high strength is required at temperatures above 500°C and up to 800°C, grade 304H is recommended. This material will retain aqueous corrosion resistance.
 
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

304 stainless steel readily work hardens. Fabrication methods involving cold working may require an intermediate annealing stage to alleviate work hardening and avoid tearing or cracking. At the completion of fabrication a full annealing operation should be employed to reduce internal stresses

Hot Working

Fabrication methods, like forging, that involve hot working should occur after uniform heating to 1149-1260°C. The fabricated components should then be rapidly cooled to ensure maximum corrosion resistance.

Heat Treatment

304 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

304 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 type 304 stainless steel is excellent both with and without fillers. Recommended filler rods and electrodes for stainless steel 304 is grade 308 stainless steel. For 304L the recommended filler is 308L. Heavy welded sections may require post-weld annealing. This step is not required for 304L. Grade 321 may be used if post-weld heat treatment is not possible.

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

Availability

Plat Durinox™ F12N is available as hot rolled sheet and plates with no. 1 (as rolled) finish.
