GETIG 630

CLASSIFICATION : AWS/SFA-5.9 : ER 630

CHARACTERISTICS :

The tig wire is designed for welding ASTM A564 type 630 and other precipitation hardening stainless steel. The composition is modified to prevent the formation of ferrite networks in the martenstic microstructure which have deleterious effect on mechanical properties. Depending on application and weld size, the weld metal may be used as-welded and precipitation hardened or welded, solution treated and precipitation, hardended.

SHIELDING GAS : Pure Argon
