Lincoln Electric Introduces UltraCore® SR-12: A New Gas-Shielded, Flux-Cored Welding Wire for Pressure Vessel Fabrication

Cleveland – Lincoln Electric introduces the new UltraCore® SR-12 gas-shielded flux-cored wire. This 75% - 80% Argon / balance CO2 gas-shielded flux-cored (FCAW-G) wire is capable of meeting AWS E71T-12M-JH8 requirements in as-welded and stress relieved conditions.


Key Features:

Robust Mechanical Properties – exceeds AWS E71T-12M-JH8 strength and low temperature impact toughness requirements in as welded and stress relieved conditions with impacts of 110 - 200 J (80-150 ft•lbf) @ -40°C (-40°F)

 Operator Friendly – premium arc performance and bead shape makes SR-12 easy to use for welders of all skill levels 











UltraCore® SR-12 is an excellent choice for pressure vessel fabrication and many other applications requiring post-weld heat treatment (PWHT) of mild steel.

This flux-cored wire conforms to AWS A5.20/A5.20M: E71T-1M-JH8, E71T-9M-JH8, and E71T-12M-JH8 classifications.

Available in 15 lb. and 33 lb. packages, UltraCore® SR-12 wire comes in the standard .045 in (1.1 mm). diameter.
