- Commodity name: Hastelloy C276 Smls& Welded Tube/Pipe
Alloy C276 seamless nickel tubing is a nickel-molybdenum-chromium alloy with addition of tungsten having excellent corrosion resistance in a wide range of severe environments. The high molybdenum content makes this alloy especially resistant to pitting and crevice corrosion. The low carbon content minimizes carbide precipitation during welding to maintain corrosion resistance in as-welded structures.
Material Grade: Hastelloy C-276, UNS N10276, Low C Ni-Cr-Mo Alloys N10276
Standard Specification: ASTM B622(Smls Pipe and Tube), ASME SB622; ASTM B626(Welded Tube); ASTM B619(Welded Pipe); ASTM B775;ISO 6207, DIN 17751, VdTüV 400/12.98

Hastelloy C-276 Description:
Hastelloy C276 is one of the most widely used Hastelloy metals due to its excellent corrosion resistance in severe environments. The composition of Hastelloy C276 makes it ideal for use with chemicals, oils and demanding environments. The low silicon and carbon content of Hastelloy C276 makes it suitable for welding applications. As one of the oldest and most corrosion-resistant alloys still used today, Hastelloy C276 has become trusted as a versatile, reliable alloy across many industries. The high nickel and molybdenum contents make the nickel steel alloy especially resistant to pitting and crevice corrosion in reducing environments. The chromium conveys resistance to oxidizing media.
