Properties of 304/304L alloy

304/304L Cold Forming

Type 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.

304/304L Hot Forming

Type 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.

304/304L Machining

Type 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.

304/304L Welding

Type 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 304/304L steel, but the molybdenum-containing austenitic stainless steel filler metals may also be considered.

304/304L Heat Treatment

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