About ER 80SB8

ER80S-B8 is a low-alloy, copper-coated steel welding wire/rod (AWS A5.28) containing ~9% Chromium and ~1% Molybdenum, used for welding similar 9Cr-1Mo ferritic steels in high-temperature, high-pressure applications like power generation and petrochemicals for creep resistance. It's an air-hardening alloy, requiring controlled preheat (around 400-500F) and post-weld heat treatment (PWHT) for optimal properties, typically used for boilers, piping, and pressure vessels.

Key Characteristics

Composition: ~9% Chromium (Cr), ~1% Molybdenum (Mo).
Application: Welding P9/T9 base metals (ASTM A335 Gr P9, A213 Gr T9, etc.).
Properties: High creep strength, resistance to elevated temperatures, and heat.
Appearance: Often copper-coated for feedability (GMAW) or bare (GTAW/TIG).
Welding Process: Used for GTAW (TIG) and GMAW (MIG).

Welding Requirements

Air-Hardening: The deposited weld metal can become hard and brittle if not properly treated.
Preheat: Required (typically 400-500F / 200-260C) to slow cooling and prevent cracking.
Interpass Temperature: Control is crucial.
PWHT: Essential (e.g., ~1375F for 1 hour) to achieve desired mechanical properties and relieve stresses.
