Stainless Steel MIG Welding Wires
RAAJMIG ER 309L
Stainless steel continuous & cut length solid welding wire for MIG/TIG welding
CLASSIFICATION : AWS/SFA-5.9: ER309L, BS 23.12.L
DIN 8556: WK. 1.4332
CHARACTERISTICS : ER309L is austenitic Stainless steel welding wire, the weld metal contains ferrite and resistance to crack is extremely good. Due to its high level of alloy, it has excellent resistance to heat.
APPLICATION : ER 309L welding wire of 22%Cr-12%Ni steel for joining ferrite to austenite stainless steel for services temperature up o 300°C . Heat resistance cast steel clad side of 18% Cr-8% Ni clad steel and stainless steel to Cr-Mo steel or carbon steel.
SHIELDING GAS : welding with 100% Ar gas Or Ar+2%O2 gas.
