1/8-hard AISI 304 is AISI 304 stainless steel in the 1/8-hard temper.304 stainless steel is a common stainless steel material. 1/8 hardness (1/8 hard) refers to the state after cold processing, which is between fully soft (fully annealed) and semi-hard (half hard). 304 stainless steel in this state has a certain hardness and strength and is suitable for some applications that require higher strength.
304 1/8 Hard Tubing is usually used in applications where requiring higher wear resistance, corrosion resistance and mechanical strength. Compared with the fully annealed state, 1/8 hardness pipes are more suitable for applications that require a certain degree of stiffness and strength, such as some mechanical, structural and manufacturing fields.
