ER90S-G Welding Wire High Toughness Low-Alloy Steel
ER90S-G Welding Wire For High Strength Steel, Vehicles And Bridges
ER90S-G Welding Wire High Toughness Low-Alloy Steel
Specification:
Solid welding wire for 2. 25 % Cr - 1 % Mo alloyed boiler, plate and tube steels. Approved for long-term service up to 1100F service temperature. Also for similar quenched and tempered steels as well as case hardening steels. The weld metal meets all prerequisites for reliable long term creep properties without embrittlement due to very low content of trace elements. Very good operating characteristics.
Purpose:
Suitable for welding 620MPa high strength steel structures, such as construction machinery, pipelines, ships, pressure vessels, etc.
