CLASSIFICATION : AWS/SFA-5.9: ER309L
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.
