Description
Super 6 90S-B3 Steel TIG Wire is a copper-coated low alloy chromium-molybdenum TIG welding wire designed for welding 2.5% Cr – 1% Mo heat-resistant steels in high-temperature and high-pressure service environments.
- Low alloy Cr-Mo TIG wire (2.5% Cr, 1% Mo classification)
- Designed for high-temperature pressure applications
- Suitable for all welding positions (PA–PF)
- Excellent mechanical strength and creep resistance
- Supplied in 5kg tubes in multiple diameters

90S-B3 TIG wire is widely used in the fabrication of boilers, pressure vessels, steam pipework, and refinery components operating under elevated temperatures. It is suitable for welding Cr-Mo steels such as 10CrMo9-10, GS 17CrMoV5 11, and 12CrSiMo8.
The copper coating supports consistent current transfer and stable arc characteristics when used with argon shielding gas and DC negative polarity. The wire provides strong tensile properties and good ductility for critical structural and pressure-retaining welds.
