Hastelloy C-276 (UNS N10276)
Category: HASTELLOY
Overview
HASTELLOY C-276 was the first wrought, nickel-chromium-molybdenum material to alleviate concerns over welding (by virtue of extremely low carbon and silicon contents). As such, it was widely accepted in the chemical process and associated industries, and now has a 50-year-old track record of proven performance in a vast number of corrosive chemicals.
HASTELLOY C-276 is available in the form of plates, sheets, strips, billets, bars,wires, pipes, tubes, and covered electrodes. Typical chemical process industry (CPI) applications include reactors, heat ex-changers, and columns.
