Recommended filler rods and electrodes for stainless steel 304 is grade 308 stainless steel. Solution treatment or annealing can be done by rapid cooling after heating to 1010-1120☌.įusion welding performance for type 304 stainless steel is excellent both with and without fillers. This means coolants and lubricants are necessary and must be used in large quantities.ģ04 stainless steel cannot be hardened by heat treatment. Low thermal conductivity of austenitic alloys results in heat concentrating at the cutting edges. Dull edges cause excess work hardening.Ĭuts should be light but deep enough to prevent work hardening by riding on the surface of the material.Ĭhip breakers should be employed to assist in ensuring swarf remains clear of the work Machining can be enhanced by using the following rules:Ĭutting edges must be kept sharp. The fabricated components should then be rapidly cooled to ensure maximum corrosion resistance.ģ04 has good machinability. At the completion of fabrication a full annealing operation should be employed to reduce internal stresses and optimise corrosion resistance.įabrication methods, like forging, that involve hot working should occur after uniform heating to 1149-1260☌.

Fabrication methods involving cold working may require an intermediate annealing stage to alleviate work hardening and avoid tearing or cracking. These precautions are necessary to avoid cross contamination of stainless steel by easily corroded metals that may discolour the surface of the fabricated product.ģ04 stainless steel readily work hardens. Tooling and work surfaces must be thoroughly cleaned before use. This material will retain aqueous corrosion resistanceįabrication of all stainless steels should be done only with tools dedicated to stainless steel materials. Where high strength is required at temperatures above 500☌ and up to 800☌, grade 304H is recommended. In this instance 304L is recommended due to its resistance to carbide precipitation. However, continuous use at 425-860☌ is not recommended if corrosion resistance in water is required. Stress corrosion cracking can occur above 60☌.ģ04 has good resistance to oxidation in intermittent service up to 870☌ and in continuous service to 925☌. Pitting and crevice corrosion can occur in environments containing chlorides. Stainless Steel Grade 1.4301/304 also corresponds to the following designations but may not be a direct equivalent:ģ04 stainless steel is typically used in:īrewery, dairy, food and pharmaceutical production equipmentģ04 has excellent corrosion resistance in many environments and when in contact with different corrosive media. It is reasonable to expect specifications in these standards to be similar but not necessarily identical to those given in this datasheet.Ĭhemical Composition Spec: EN 10088-2:2005 1.4301 Steel Chemical Element ASTM, EN or other standards may cover products sold. Property data given in this document is typical for flat rolled products covered by EN 10088-2:2005. Some products such as plate and pipe may be available as “dual certified” material that meets the criteria for both 304 and 304L.ģ04H, a high carbon content variant, is also available for use at high temperatures. It is used in heavy gauge components for improved weldability. Type 304L is the low carbon version of 304. This property has resulted in 304 being the dominant grade used in applications like sinks and saucepans. Type 304 stainless steel is an austenitic grade that can be severely deep drawn. 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. Type 304 is the most versatile and widely used stainless steel. Stainless steel types 1.4301 and 1.4307 are also known as grades 304 and 304L respectively.
