Bright Cold Rolled Stainless Steel Sheets Hastelloy C276 Nickel Alloy Steel Plate
1. Introduction
Alloy C276 nickel alloy plate (UNS N10276) is an austenitic Ni-Mo-Cr alloy with a small amount of tungsten added. It is one of the primary corrosion resistant materials available for processing industry. Alloy C276 nickel alloy plate has excellent corrosion resistance in both oxidation and reduction environments.
The combination of high mo and CR contents and the addition of W make C276 ni alloy plate highly resistant to chloride stress corrosion cracking, pitting corrosion, crevice corrosion and general corrosion.
Alloy C276 nickel alloy plates can be operated in oxidizing atmospheres up to 1900oF (1038oC); however, the alloy lacks sufficient chromium content to operate successfully in the most intense oxidizing environments (such as hot concentrated nitric acid).
The low carbon content of alloy C276 nickel alloy plate enables the alloy to be used in the welded state. It cannot be hardened by heat treatment, but can be hardened by cold work. This alloy has a higher work hardening rate than austenitic stainless steel and should be considered.
Alloy C276 nickel alloy plates can be easily welded and machined using standard shop manufacturing practices of austenitic stainless steel and nickel base alloys.
