Stainless Steel Welding Electrode E BK 310-16
Rutile type stainless steel electrode for welding heat-resisting chromium and chromium nickel steels as well as cast steels. Weld metal deposit is fully austenitic stainless steel, containing 25% chromium and 20% nickel. Suitable for welding heat treatment and industrial furnaces and equipment which are subjected to service temperatures up to 1200°C. Weld metal is non scaling up to 1250°C. Especially it is resistant to hot crack. Exhibits high Charpy impact energy at low temperatures. Weld metal is not corrosion resistant to sulfurous combustion gases. Possible to use equally well both with AC and
Applications
Common applications include industrial furnaces, annealing chambers, fused salt treatment installations, boiler parts, as well as heat exchangers.. PRO
