StarBlaze TIG Wire ER312

STARBLAZE TIG 312 is a high-alloy, duplex stainless steel TIG welding rod designed for joining difficult-to-weld steels, dissimilar metals, and unknown steel grades.
It conforms strictly to the AWS/SFA A5.9 ER312 standard.
Often referred to as the ultimate "problem solver" or "super missile" wire, its microstructure yields a high-ferrite matrix that gives the weld deposit an exceptional resistance to hot cracking, even under severe constraint or dilution.

Product Overview & Composition
Alloy Classification: Conforms precisely to international standards AWS/SFA A5.9: ER312 and EN ISO 14343-A: W 29 9.
Chemical Profile: Formulated with a rich chemistry of 29% Chromium (Cr) and 9% Nickel (Ni).
Microstructure: Forms a two-phase duplex (ferrite-austenite) weld metal, with a high ferrite number (typically FN >30) that resists cracking under heavy stress.
Dilution Resistance: Maintains superior structural integrity and corrosion resistance even when heavily diluted by carbon steel base metals.
