Product Description
DIN 1.2316 (X36CrMo17 / X38CrMo16) is a martensitic stainless tool steel specifically engineered for plastic mold applications where high corrosion resistance, high polishability, and uniform hardness across heavy cross-sections are required. Containing 15.00 to 17.50 percent chromium and 0.80 to 1.30 percent molybdenum, it offers superior resistance to corrosive plastics (such as PVC and recycled materials) compared to standard 1.2083 / AISI 420 steels. It is typically supplied in a pre-hardened condition (280 to 325 Brinell).
