ER90S-B3 High Tensile welding wire
EN ISO 21952-B:2007:G 62 2C1M
AWS A5.28-05 ER90S-B3
JIS Z 3317:G 62-2C1M
Solid wire electrode, copper coated for welding in boiler, pressure vessel and pipeline construction.and for the petrochemical industry, e.g. cracking plants. Preferred for 10CrMo9-10, and also suitable for similar-alloy quenched and tempered and case-hardening steels. Approved for long-term use at operating temperatures of up to +600°C. The weld metal exhibits high quality, good toughness and crack resistance, as well as a creep strength very much in the same range as 10CrMo9-10.The wire electrode has very good sliding and feeding characteristics. Good copper adhesion,low total copper content. Very good welding and flow behaviour.
TIG/GTAW rod for high temperature creep resistant 2.25%Cr-1%Moferritic steel. These steels are used for creep resisting applications up to ~600°C, Typical applications in power generation plant include steam piping, turbines and boilers, the alloy also finds applications in the chemical and petro-chemical industries. The wire has low levels providing a low Bruscato(X)of tramp elements(eg.Sn,As,Sb & P)Factor for temper embrittlement resistant applications.
