Stainless Steel Electrodes
ES 307 B A5.4: E 307- 15 / EN 1600: E 18 8 Mn B 22
Description
ES 307 B - IS a basic coated electrode, Austenitic stainless-steel electrode producing a weld metal with less than 5% ferrite. The tough weld metal has excellent crack resistance, even when welding steels with very poor weldability. Suitable for joining 12-14% manganese steel to itself or other steels. Also suitable for buffer layers before hardfacing, . Weld beads are highly resistant to oxidation at operating temperatures up to 850°C.
