NS1402 alloy is a Ti-stabilized Ni-Fe-Cr-Mo-Cu corrosion resistant alloy, this article mainly introduces the production process of the alloy pipe development, discusses its smelting and processing technology characteristics, analysis of chemical composition and processing technology The strength of the alloy, improve the intergranular corrosion performance, and finally compare the performance of the developed products with the imported materials. It shows that the domestic NS1402 can be comparable with the imported materials, and the corrosion performance is better than the imported materials.
