EX6300000001250TL0 - Exocor ER630 (17-4 PH) Stainless TIG Rod 3.2mm

Premium ER630 Stainless Steel TIG Rods for High-Strength Alloys

The Exocor ER630 Stainless Steel TIG Rod (3.2mm) is a specialized welding consumable designed for joining precipitation-hardening stainless steels, most notably the 17-4 PH (ASTM A564 Type 630) alloys. This martensitic stainless steel filler metal is engineered to provide a weld deposit that matches the mechanical properties and corrosion resistance of the base material, making it an essential choice for industries requiring high-performance fabrication, such as aerospace, chemical processing, and marine engineering.

ER630 is characterized by its ability to be heat-treated. While the as-welded structure is martensitic and possesses high strength, post-weld heat treatment (PWHT) allows the material to achieve its full potential in terms of hardness and ductility. This makes it ideal for repairing or fabricating components like pump shafts, valve parts, and turbine blades where durability under stress is paramount. The 3.2mm (1/8") diameter is well-suited for filling larger joints and multi-pass welding applications on thicker sections of material.

At Josef Gas, we supply Exocor consumables because of their consistent quality and reliability. These rods are manufactured to strict standards to ensure a clean surface finish, which promotes smooth feeding and a stable arc. When welding with ER630, pure Argon shielding gas is recommended to maintain the integrity of the alloy and prevent contamination. Whether you are performing critical repairs or manufacturing new high-strength components, these rods deliver the metallurgical performance required for demanding specifications.
