CLASSIFICATIONS: E309T1-1, E309T1-4 per AWS A5.22

SelectAlloy 309H-AP is a gas-shielded, flux cored, stainless steel electrode with a nominal weld metal composition of 24% chromium and 13% nickel with a carbon content of .04-.08%. The higher carbon in this all position alloy wire makes it suitable for higher temperature use.

APPLICATIONS: SelectAlloy 309H-AP is utilized to weld type 309 stainless steel where higher temperature strength is required. This electrode may also be used to join carbon and low alloy steels to austenitic stainless steels. SelectAlloy 309H-AP is well suited for refinery and chemical processing equipment welding.
