Low-alloyed Electrodes

ES 8018 B2 A5.5: E 8018-B 2 / EN 1599: E CrMo 1 B 42 H5

Description

ES 8018 B2 is a basic coated electrode. It gives a CrMo alloyed weld metal that is used in the welding of creep resistant pressure vessels and pipe steels operating under high temperatures. HS - 5 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. Re-drying is 350°C - 400°C min 2 h.

Applications

ES 8018 B2 is used for the welding of steam boilers and steam pipes and pressure vessels that are manufactured from Cr - Mo steels. It can also be used in welding similarly alloyed cementation steels, nitrided steels, heat treatable steels and cast steels. It is an ideal electrode in the multi-pass welding of thick sectioned and rigidly restrained mass structures.
