CEWELD® ER 70S-B2L Tig is a low carbon variant of the ER80S-B2 and was developed for welding 1¼Cr/½ Mo steel, which requires a lower hardness in the welded condition. Typical applications can be found in power plant construction, pressure pipe, turbine and boiler construction as well as mountain bikes, vehicle frames, stock cars and creep-resistant steels.

CEWELD® ER 70S-B2L TIg is identical to ER80S-B2, with the exception of the reduced carbon content. This results in lower hardness and strength values, which reduces the tendency to crack, especially if the weld seams are not heat-treated. These steels are usually used for operating temperatures up to 550°C. The low proportion of accompanying elements (Sn, As, Sb, P) in the wire ensures a low Bruscato factor (X < 10 ppm) and therefore insensitivity to temper embrittlement.
