StarBlaze PRIME 312 is a premium, rutile-basic coated stainless steel stick welding electrode (rod). Classified under AWS A5.4 as E312-16, this electrode deposits a high-ferrite 29% Chromium / 9% Nickel microstructure, earning its global reputation as the ultimate "problem solver" or universal repair rod for difficult-to-weld, dissimilar, and highly crack-sensitive steels.
Core Product Features
Extreme Crack Resistance: The high-ferrite matrix (typically Ferrite Number 30–50) provides immense dilution tolerance, absorbing heavy shrinkage stress and completely suppressing hot cracking.
Universal Dissimilar Joining: The perfect metallurgical match for bonding entirely different metal groups, such as stainless steel to carbon steel, tool steel, spring steel, or manganese armor plating.
Work-Hardening Buffer Pass: Serves as an outstanding, impact-absorbing cushion or buffer layer before applying tough hardfacing alloys onto heavily worn industrial machinery.
Superb Operating Characteristics: Delivers a stable, low-spatter arc on both AC and DC systems, accompanied by a self-releasing slag that reveals a clean, finely rippled weld profile.
AWS Specification: AWS A5.4 / A5.4M (Classification: E312-16 or E312-17 depending on the flux coating)
