Hastelloy C276 is a nickel-molybdenum-chromium alloy that also contains iron and tungsten, making it capable of enduring a wide array of aggressive chemical conditions. Its typical makeup features around 57% nickel, 16% molybdenum, 15.5% chromium, 5% iron, and 3.5% tungsten. This alloy is known for its remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking. In terms of mechanical properties, C276 bars and rods exhibit tensile strength ranging from 690 to 785 MPa, yield strength between 283 and 365 MPa, and an elongation of about 40 to 50%. These characteristics remain consistent across different temperatures, and the alloy is also recognized for its good fabricability and weldability.
