RATNA 630-16 (AWS A5.4 E630-16)

An Electrode specially designed for producing 17Cr-4.5Ni-3.5Cu weld deposit for precipitation-hardening stainless steels

Classification:

AWS/SFA-5.4: E630-16
UNS W37410

Characteristics:

This electrode is specially designed so that the weld metal is modified to prevent the formation of ferrite networks in the martensite microstructure, which could negatively affect mechanical properties. It offers a combination of strength, corrosion resistance, and machinable weld metal.

Application:

Suitable for joining ASTM A-564 hardenable steels.
Depending on application and weld size, weld metal can be used 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.
