Properties of AISI 304H Stainless Steel
304H SS Cold Forming
304H Stainless Steel 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.
304H SS Hot Forming
304H Stainless Steel 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.
304H SS Machining
304H Stainless Steel 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.
304H SS Welding
304H Stainless Steel is readily welded by a full range of conventional welding procedures (except oxyacetylene). AWS E308H/ER308H filler metals should be used with Type 304/304H steel. After welding Type 304H it may be necessary to fully anneal to restore the corrosion resistance lost by sensitization to intergranular corrosion when chromium carbides were precipitated in the grain boundaries in the weld heat-affected zone.
304H SS Heat Treatment
Annealing: Type 304H should be heated to 1900ºF minimum and water quenched or rapidly cooled by other means.
Hardening: Type 304H cannot be hardened by heat treatment. However, Type 304H can be hardened by cold working.
