Properties of Stainless Steel 304/304L Alloy

Stainless Steel 304/304L Cold Forming

Type AISI 304/304L is readily formed and fabricated through a full range of cold working operations. It can be used in heading, drawing, bending, and upsetting. Any cold working operations will increase the strength and hardness of the material, and may leave it slightly magnetic.

Stainless Steel 304/304L Hot Forming

Type AISI 304/304L can be forged in the 1700-2200°F range. For maximum corrosion resistance, forgings should be annealed at 1900°F minimum and water quenched or rapidly cooled by other means after hot working operations.

Stainless Steel 304/304L Machining

Type AISI 304/304L is a tough austenitic stainless steel subject to work hardening during deformation and, unless modified for improved machining response, is resistant to chip breaking. The best machining results are achieved with slower speeds, heavier feeds, excellent lubrication, sharp tooling, and powerful, rigid equipment.

Stainless Steel 304/304L Welding

Type AISI 304/304L is readily welded by a full range of conventional welding procedures (except oxyacetylene). AWS E308L/ER308L filler metals should be used with Type AISI 304/304L steel, but the molybdenum-containing austenitic stainless steel filler metals may also be considered.

Stainless Steel 304/304L Heat Treatment

Annealing: Type AISI 304/304L should be heated to 1900ºF minimum and water quenched or rapidly cooled by other means.
Hardening: Type AISI 304/304L cannot be hardened by heat treatment. However, Type AISI 304/304L can be hardened by cold working.
