ALLOY 630 Stainless Steel SAW wire

ALLOY 630 Stainless Steel SAW wire

Filler metal ALLOY 630 is a precipitation hardening stainless steel used for welding of materials of similar chemical composition.
ALLOY 630 is primarily designed for welding ASTM A-564, type 630 (17 chromium, 4 nickel), and precipitation hardenable steel.
This wire offers the combined characteristics of a strong, corrosion resistant, easily machinable weld metal.
Depending on the weld dimensions and applications, Filler metal ALLOY 630 may be used in the as welded, welded plus precipitation hardened, or welded plus solution treated plus precipitation hardened condition.

Mechanical properties of this alloy are greatly influenced by the heat treatment.
