Price:
R.F.Q.
SSA6582 is a nickel-chromium-molybdenum alloy steel known for its exceptional strength, toughness, and wear resistance. It contains high levels of nickel and chromium, which contribute to its hardenability and high tensile strength. The use of SSA6582 steel is widespread across various industry sectors, particularly in applications demanding higher tensile and yield strength compared to what SSA7225 steel offers. We import from Europe, Japan and China.
