NS312

Detail

NS312

Materialgrade: NS312 corrosion resistant alloy

US grade: UNS N06600

German grade: W,Nr,2.4816

Ioverview:

NS312 (N06600, 2.4816) alloy is an earlydevelopment of nickel-chromium-iron-based solid solution strengthening alloy,which has good high temperature corrosion resistance and oxidation resistance,excellent hot and cold processing and welding process performance, and issatisfactory below 700 °C, Thermal strength and high plasticityNS143 The alloycan be strengthened by cold working, or it can be connected by electricresistance welding, fusion welding or brazing, It can supply cold rolledsheets, hot rolled slabs, strips, wires, bars, round cakes, ring blanks, ringforgings, etc, It is suitable for making anti-oxidation parts with low loadbelow 1100 °CNS143
