deion
? midalloy mastercor?1?7?1?7 e309t1-1/4 and e309ht1-1/4 are gas shielded flux-cored wires designed for all-
b welding and can be used with 75% argon / 25% co2 or 100% co2 shielding gas.
applications
? midalloy mastercor?1?7?1?7 e309t1-1/4 and e309ht1-1/4 have a nominal comb of 23.5% cr and 13% ni,
and is used for joining similar alloys in wrought or cast bs.
? midalloy mastercor?1?7?1?7 e309t1-1/4 and e309ht1-1/4 are used for dissimilar welds between carbon and low-
alloy steels to austenitic stainless steels.
? midalloy mastercor?1?7?1?7 e309t1-1/4 and e309ht1-1/4 are used for 1st layer cladding of carbon steel and for
welding the stainless steel side of type 304 clad sheets.
? midalloy mastercor?1?7?1?7 e309t1-1/4 and e309ht1-1/4 can be used to weld type 304 base bls where severe
corrosion conditions exist that require higher alloy content in the weld bl.
