Low-alloyed Electrodes
ES 8013 B2 A5.5: E 8013-B2H4R / EN 1599: E CrMo 1 R 12
Description
ES 8013 B2 It is a rutile coated electrode. It gives a Cr-Mo alloyed weld metal that is used in the welding of creep resistant pressure vessels and pipe steels operating under high temperatures. It is especially used for 13 CrMo 44 type steels that are frequently used in operating temperatures up to 570°C. It gives a root pass free of porosity with a minimum amount of spatter.
