NS131 (NS1301) Iron-nickel-based corrosion-resistant alloy overview:

NS131 corrosion-resistant alloy is an iron-nickel-based corrosion-resistant alloy developed in China in 1967 with excellent pitting corrosion resistance, also known as the new No. 9 alloy. Due to the high chromium content in the alloy, combined with the appropriate amount of molybdenum, this alloy has good corrosion resistance to oxidizing and reducing media, especially pitting corrosion resistance in redox composite media containing CL and other active anions The performance is even better.

NS131 is an alloy composed of nickel and other elements. It is a kind of nickel-chromium alloy, nickel-iron alloy, nickel-copper alloy and nickel-molybdenum alloy. Nickel has good mechanical, physical and chemical properties. Adding appropriate elements can improve its oxidation resistance, corrosion resistance, high temperature strength and improve certain physical properties. Has excellent corrosion resistance and oxidation performance, from low temperature to 980 ℃ have good tensile properties and fatigue properties, and resistance to stress corrosion in salt spray atmosphere.
