OVERVIEW

Premium Low-Alloy TIG Filler for High-Temperature Service

The Exocor ER80S-B2 TIG Welding Rod is a high-performance low-alloy steel filler metal specifically engineered for joining creep-resistant steels. Formulated with a nominal composition of 1.25% Chromium and 0.5% Molybdenum, this rod is the industry standard for welding 1-1/4 Cr - 1/2 Mo steels. These base materials are ubiquitous in the power generation, petrochemical, and refinery industries, particularly in applications involving high-pressure piping, boilers, and pressure vessels that operate at elevated temperatures. The addition of chromium and molybdenum provides the weld deposit with significant resistance to creep and corrosion, ensuring structural integrity in harsh service environments.

Compliance with AWS A5.28 specifications guarantees that the Exocor ER80S-B2 meets rigorous quality standards for chemical composition and mechanical properties. When using this filler metal, strict adherence to welding procedures is critical. To avoid cold cracking and ensure the formation of a sound metallurgical bond, preheat and interpass temperatures must be maintained at a minimum of 300°F (150°C). Furthermore, this alloy is classified based on its properties after Post Weld Heat Treatment (PWHT). Proper stress relief is essential to restore ductility and toughness to the weld zone, making it suitable for its intended service life.

This 10lb tube of 3/32" cut lengths offers a convenient supply for professional fabricators handling critical pipe welding or repair jobs. The rods are manufactured with tight tolerances on diameter and a clean surface finish, promoting smooth feeding and a stable arc under 100% Argon shielding gas. Whether for new construction or maintenance of steam lines and heat exchangers, Exocor ER80S-B2 delivers the reliability required for code-quality welds.

FAQ

It is primarily used for welding 1-1/4 Chromium - 1/2 Molybdenum steels typically found in high-temperature service applications like power plants and refineries.

Yes, a minimum preheat and interpass temperature of 300°F (150°C) is essential to prevent cracking in the weld and heat-affected zone.

Yes, ER80S-B2 is classified based on properties after PWHT. Heat treatment is usually required to relieve stress and restore ductility to the weldment.

100% Argon is the standard shielding gas for TIG welding with ER80S-B2.

These are 3/32" diameter rods cut to a standard length of 36 inches.

While it can physically weld mild steel, it is not recommended due to cost and the risk of cracking if not properly heat treated. It is specifically designed for Cr-Mo alloy steels.

This product meets the requirements for AWS A5.28 class ER80S-B2.
