AWS: E16.8.2-17
Typical Applications
Welding Positions:
The 16.8.2 consumables have a controlled composition, optimized for performance in structural service at temperatures up to 1,472° F (800°C).
Low total of Cr+Mo with control C and ferrite content ensures high resistance to thermal embrittlement.
No bismuth bearing constituents are in the design, ensuring <0.002% Bi as required by API 582. (API = American Petroleum Institute; standard 582 is welding guidance on Chemical, Oil, and Gas industries).

FEATURES
Manufactured with controlled hydrogen and moisture resistant flux covering technology to ensure high resistance to weld porosity
For 304H, some authorities now choose 16.8.2 specifically to avoid hot ductility and creep-fatigue problems in thick sections which traditionally would have been welded with 308H
Historically, this weld metal was initially developed to avoid in-service HAZ failure in 347H of >12mm thickness
