ASTM B575 Hastelloy C-276 Plate,UNS N10276 Plates/Sheets
We are the professional supplier and exporter of ASTM B575 Hastelloy C-276 Plate,UNS N10276 Plates/Sheets in China
Hastelloy C276 Sheet / Plate are corrosion resistant to oxidization and stress cracking. They are also resistant to pitting. The 57% nickel content provides the material with high corrosion resistance. Roopam Steel is a leading manufacturer of the Hastelloy C276 sheets and plates.
N10276 ,Hastelloy C-276 is a nickel-molybdenum-chromium-tungsten alloy with excellent general corrosion resistance and good fabricability. The alloy should be considered for use in environments where resistance to hot contaminated mineral acids, organic and inorganic chloride-contaminated media, chlorine, formic and acetic acids, acetic, acetic anhydride, sea water and brine solutions is desired.
N10276,Hastelloy C-276 has resisted the formation of grain boundary precipitates in the weld heat-affected zone, making it a candidate for most chemical and petrochemical processing applications in the as-welded condition. The alloy has resisted both general and localized corrosion, including pitting, crevice corrosion, and stress corrosion cracking.
N10276 ,Hastelloy C-276 is readily fabricated by welding, using methods similar to those utilized for nickel-based alloys.
Grade: Alloy C22/622, Alloy C4, Alloy C276, Alloy 59, Alloy 686, Alloy C2000.
UNS Number: UNS N06022, UNS N06455, UNS N10276, UNS N06059, UNS N06686, UNS N06200
