ER312 Arc Mig Wire For 304 Stainless Steel 308 309l

Product Description

ER312 Stainless Steel Gas Shielded Arc Welding Wire

AWS A5.9: ER312 is a solid wire electrode for GMAW, suitable for welding or surfacing hardly weldable steels. Suitable to weld buffer layers of hard depositions. The excellent mechanical properties and the notch resistance make this wire of general use.

Application
ER312 is used to weld cast alloys of similar composition and is used to weld dissimilar metals and weld overlays. This alloy has very high ferrite. When welding similar cast alloys, limit welding to two or three layers only.
