90S-B3 Steel TIG Welding Rods

The ER90S-B3 TIG rods are designed for TIG welding applications that involve high-temperature service conditions and require exceptional strength and toughness. These rods are crafted from a low-alloy steel that contains 2.25% chromium and 1% molybdenum, making them highly effective for welding creep-resistant steels used in high-pressure, high-temperature environments such as those found in the power generation and petrochemical industries. The ER90S-B3 rods offer excellent resistance to oxidation and corrosion at elevated temperatures, ensuring durable and long-lasting welds. They are particularly suited for applications like repairing and constructing boilers, pressure vessels, and heat exchangers. The composition of the ER90S-B3 rods provides a stable arc, smooth flow, and a clean finish, crucial for maintaining the integrity of critical welds in harsh operating conditions.
