1Cr11Ni2W2MoV martensitic heat-resistant heat-resistant stainless steel is a low-carbon 12% Cr steel with a large amount of W, Mo, V and other ferrite-forming elements that reduce the austenite phase region, so that the steel has a martensitic transformation Hardenability, 13Cr11Ni2W2MoV is a martensitic heat-resistant stainless steel with excellent comprehensive mechanical properties. It has high room temperature tensile strength, high endurance strength and high creep limit. It has been widely used in the aviation industry to make engine rods that work below 600°C. , Bolts, sealing rings, bushings, pin shafts, blades, discs, shafts and other important parts. Comply with GJB 2294-95, GJB 2294A-2014, HB5024-89 standards
