ERNiCrMo-4 - Nickel C 276 TIG Welding Rod HASTELLOY- C-276 RTW- Filler Metal Hastelloy C276 Welding Wire UNS N10276 ERNiCrMo-4 HASTELLOY- C-276 Coated ElectrodesAlloy C276 is a nickel-chromium-molybdenum filler metal developed for MIG and TIG welding
Hastelloy C-276 / UNS N10276 / DIN W. Nr. 2.4819 welding wire
Alloy C276 is a nickel-chromium-molybdenum filler metal
developed for MIG and TIG welding of Hastelloy C and Hastelloy C-276
to themselves, to stainless steel or to other nickel base alloys. Alloy C276 offers excellent resistance to pitting, stress-corrosion cracking and oxidizing atmospheres up to 1900oF.
Applications This filler metal is frequently used for welding the clad side of joints on steel in the chemical, petrochemical and petroleum industries.

Corrosion Resitance:
Alloy C276 is one of the premier corrosion resistant materials that performs exceptionally well in both oxidizing and reducing environments. It resists chloride stress corrosion cracking, pitting, crevice and general corrosion. The alloy is also resistant to carbide precipitation during welding enabling it to be utilized in the as-welded condition.
Alloy C276 is highly resistant to concentrated solutions of oxidizing salts including iron and copper chloride. It also performs well in seawater, especially under crevice conditions where other frequently used alloys such as stainless steel, Alloy 400 and Alloy 625 fail.
