About ER 90SB9

The classification ER90S-B9 refers to a specific type of low-alloy steel welding filler wire/rod designed for high-integrity structural service at elevated temperatures, particularly in power generation and petrochemical industries.

Key Features and Composition

Composition: ER90S-B9 is a 9% chromium (Cr), 1% molybdenum (Mo) modified steel, with controlled additions of niobium (Nb), vanadium (V), and nitrogen (N).
Properties: This chemical composition provides improved long-term creep strength, toughness, fatigue life, oxidation resistance, and corrosion resistance when operating at high temperatures (up to 650C) and high pressures.
Welding Performance: It offers stable arc characteristics, smooth welding performance, and produces welds of radiographic quality.

Applications

ER90S-B9 is primarily used for welding creep-resisting steels, such as P91, T91, and F91 grades (e.g., ASTM A213-T91 tubes, ASTM A335-P91 pipes, and ASTM A387 Grade 91 plates).

Typical applications include:

Headers, main steam piping, and turbine rotors in fossil-fueled power-generating plants.
Oil refineries and petrochemical plants.
Gasification plants.

Welding Requirements

Welding with this filler metal typically requires controlled preheating, interpass temperature control, and mandatory post-weld heat treatment (PWHT) to prevent cracking and ensure optimal mechanical properties.

It is available as both solid wire for Gas Metal Arc Welding (GMAW/MIG) and cut-length rods for Gas Tungsten Arc Welding (GTAW/TIG).
