These 310 stainless steel electrodes feature a rutile coating for welding 25/20 chromium nickel heat resisting steels.

Ideal for austenitic stainless heat resistant steels including AISI type 310 and Firth Vickers Immaculate 5; the weld deposit provides good heat resistance up to 1400°C in air and 650°C in oxidising sulphurous atmospheres.

These electrodes are also suitable for welding stainless to carbon or low alloy steels; making them a great choice for foundry heat treatment applications.
