ASME SFA 5.22 E312T0-1/-4 or E312T1-1/-4
E312T-1 is a flux-cored AISI 312 type stainless steel alloy wire with exceptionally good operating characteristics. E312T-1 produces dense, tough deposits having the highest tensile strength of any of the austenitic stainless steels. E312T- 1 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 will work-harden up to 38 RC. E312T-1deposits are resistant to heat corrosion and wear. The unique metallurgical structure of USA E312T-1 is that of ferrite suspended in an austenite matrix. This makes the deposits extremely resistant to cracking.
Applications:
E312T-1 is used to weld base metals of similar analysis as well as dissimilar steels. 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. E312T-1 is also an excellent choice as an underlay (buffer layer) for hard facing deposits.
