NSSC FW2

NSSC FW2 is an extra low-interstitial ferritic stainless steel with low alloy element content (no addition of Ni or Mo). The NSSC FW series has corrosion resistance equal to or greater than the 18Cr or 18Cr-8Ni stainless steels. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming. Filing Code: SS-1113. Producer or source: Nippon Steel & Sumikin Stainless Steel Corp.. Originally published January 2012, corrected December 2019.

Research on the Performance and Process of Fe/Cr-V – WC Surfacing Welding Layer on Weapons Parts Department

In this paper,a Fe/cr-v - WC flux-cored wire welding alloy which used in weapons parts wear surfacing is developed. By the analysis of the average hardness of surfacing welding layer, the wear weightlessness and the microstructure, the wear resistance properties of surfacing welding alloy is studied. And the cored in alloying elements Cr, WC, Mo and V on the influence law of hardness and wear resistance of surfacing welding layer are systematically discussed, So as to the best alloy element content in the cored is determined. Results are showed that Cr element content is 5.5% ~ 5.5%, the content of WC powder is 3.9% ~ 4.2%, at 1.6%, content of Mo element V element content is within 3.2%. with the Fe/Cr - WC flux-cored wire welding alloy ratio appropriate, weapons parts welding layer has good hardness and abrasion resistance.
