Single values are maximum unless otherwise specified. Description and Applications E312T-1 is a flux-cored AISI 312 type stainless steel alloy wire with exceptionally good operating characteristics. It produces dense, tough deposits having the highest tensile strength of any of the austenitic stainless steels. Weld deposits match the characteristics and mechanical properties of AISI 312 base metal. Weld deposits are approximately 23 Rockwell C as applied. Machining should be done with slow feed rates as the weld deposits are resistant to heat, corrosion and wear. The unique metallurgical structure is that of ferrite suspended in an austenite matrix. This makes the deposits extremely resistant to cracking. It is used to weld base metals of similar analysis as well as dissimilar steels. Inweld E312T-1 performs well on abrasion-resisting steels, manganese steels, hardening steels, spring steels, armor plate, high-yield steels and for joining high temperature steels to carbon and low alloy steels. An excellent choice as an underlay (buffer layer) for hard-facing deposits.
