1Cr11Ni2W2MoV, 13Cr11Ni2W2MoV, 961 martensitic heat-resistant stainless steel

1Cr11Ni2W2MoV (13Cr11Ni2W2MoV) martensitic thermally strong and heat-resistant stainless steel is a low-carbon 12% Cr steel added with a large amount of W, Mo, V and other ferrite forming elements that reduce the austenite phase region, so that the steel has martensitic properties. Bulk transformation hardening ability, 13Cr11Ni2W2MoV is a martensitic heat-resistant stainless steel with excellent comprehensive mechanical properties, high tensile strength at room temperature, high lasting strength and creep limit, and has been widely used in the aviation industry to manufacture work below 600 ℃ Engine tie rods, bolts, seal rings, bushings, pins, blades, discs, shafts and other important parts. Comply with GJB 2294-95, GJB 2294A-2014, HB5024-89 and other standards.

Our company has nearly 100 tons of 1Cr11Ni2W2MoV electroslag ingots in stock all the year round, with complete ingot types, fast delivery speed and GJB quality. Contact number: +86-13880490406
