CLASSIFICATIONS: EC309 and EC309L per AWS A5.22 (Also per AWS A5.9;2006)

SelectAlloy 309LCR-C is a specially designed gas-shielded, metal cored, stainless steel electrode with increased resistance to cracking. It has a nominal composition of 24% chromium, 13% nickel, 0.02% carbon and a small addition of titanium.

APPLICATIONS: This wire is utilized for making small butt, lap and fillet welds on thin material at elevated speeds. SelectAlloy 309LCR-C is used in the welding of refinery and chemical processing equipment as well as furnace and auto exhaust parts. It also welds Type 309 stainless steel, to join carbon and low alloy steels to austenitic stainless steels, and in the welding of dissimilar materials where cracking may be a problem.

DIAMETERS: .035", .045", 1/16"

SHIELDING GASES: Ar/1-2% O2, Ar/1-2% CO2, 40-55 cfh
