Product details

Now I often encounter some people in the industry asking about the 1Cr11Ni2W2MoV material. Today I will talk about the composition and characteristics of this material. 1Cr11Ni2W2MoV stainless steel is also called 961 stainless steel. The latest grade is 13Cr11Ni2W2MoV, and the digital grade is S47310.

The grade in the GJB 2294-95 and GB/T 1221-92 standards is 1Cr11Ni2W2MoV. After the new GB/T 1221-2007 standard is promulgated, the grade is updated to 13Cr11Ni2W2MoV. This material is a chromium-nickel tungsten-molybdenum-vanadium martensitic heat-resistant steel with good The toughness and oxidation resistance, and good corrosion resistance in fresh water and humid air. Mainly in the aviation industry, it has been widely used in the manufacture of engine blades, disks, shafts and other important parts that operate below 600°C.
