AWS Class ER80S-B8 is a low-alloy steel filler wire that contains around 9% Chromium and 1% Molybdenum, making it perfect for TIG and MIG welding processes. It boasts impressive creep resistance and oxidation resistance at high temperatures. Typical mechanical properties include a tensile strength ranging from 80,000 to 95,000 psi (550 to 655 MPa), a yield strength of 65,000 psi (450 MPa), and an elongation of 20 to 25%. The weld metal is suitable for post-weld heat treatment (PWHT) and provides stable arc characteristics, minimal spatter, and excellent fusion, making it a great choice for code-quality welds in high-pressure systems.
