ER90S-B3 Steel TIG Welding Rods
ER90S-B3 TIG rods are designed for TIG welding applications that involve high-temperature service conditions and require exceptional strength and toughness. Crafted from a low-alloy steel containing 2.25% chromium and 1% molybdenum, they're highly effective for welding creep-resistant steels used in high-pressure, high-temperature environments such as power generation and petrochemical industries. They offer excellent resistance to oxidation and corrosion at elevated temperatures, ensuring durable, long-lasting welds, and are particularly suited to repairing and constructing boilers, pressure vessels, and heat exchangers. Available in 1/16", 3/32", and 1/8" diameters.
