What is the hardness of 904l stainless steel?
904L is a copper-containing, high-nickel, molybdenum super austenitic stainless steel. Its implementation standards include ASTM A240/A240M (American standard) and EN 10088-2:2005 (European standard). The corresponding national standard is 015Cr21Ni26Mo5Cu2. It far exceeds conventional stainless steels such as 316L and is an ideal material for harsh chemical environments.
