13Cr-2Ni Duplex Stainless (var. 3)
metalA modified 13% chromium, 2% nickel duplex stainless steel alloyed with tungsten and cobalt to achieve elevated hardness and strength, placing it in the family of martensitic/duplex hybrids designed for high-strength service. This variant appears optimized for demanding applications requiring both corrosion resistance and exceptional mechanical strength, serving as an alternative to conventional 13Cr martensitic or austenitic grades where standard duplex stainless steels provide insufficient hardness. The tungsten and cobalt additions suggest use in wear-resistant and fatigue-critical environments where standard lean-duplex or super-duplex alloys would be underspecified.
