What is AWS Class ERZr2 MIG and TIG Filler Metal?

AWS Class ERZr2 is a commercially pure zirconium filler metal (Grade 2) that typically contains ≥99.2% zirconium along with trace amounts of hafnium, oxygen, nitrogen, iron, and carbon. It boasts remarkable corrosion resistance, especially in harsh acids like hydrochloric and sulfuric acid. Its mechanical properties include a tensile strength ranging from 344 to 483 MPa (50 to 70 ksi), along with excellent ductility and impact toughness. When proper shielding techniques are applied, ERZr2 is highly weldable and meets ASTM B863 standards. This filler metal is essential in applications where corrosion resistance and metallurgical stability are vital for longevity.
