An Electrode specially designed for producing 17Cr-4.5Ni and 3.5 Cu weld deposit precipitation-hardening stainless steels
CLASSIFICATION : AWS/SFA-5.4: E630-16
UNS W37410
CHARACTERISTICS : An electrode specially designed for weld metal is modified to prevent the formation of ferrite networks in the martensite microstructure which could have a deleterious effect on mechanical properties. This electrode offers the combined characteristics of a strong, corrosion resistant, electrode gives machinable weld metal.
1) Suitable for joining ASTM A-564 hardenable steels
2) Dependent on the application and weld size, the weld metal may be used either as-welded, welded and precipitation hardened , or welded, solution treated and precipitation hardened.
RE-DRY CONDITION : Re-Dry the electrode at 250°C for 1 hrs before use.
