About E 308HT-1

The E308HT1-1 is an AWS-classified, gas-shielded, flux-cored stainless steel welding wire used for welding Type 304H stainless steel and similar austenitic steels, featuring high carbon (H) for improved strength at elevated temperatures (above 400C/750F). It's designed for all-position welding (T1), offers a smooth arc, low spatter, easy slag removal, and is typically used with 100% CO or an Argon/CO mix, making it ideal for high-temperature applications like boilers, heat exchangers, and petrochemical equipment.

Key Characteristics:

E (Electrode): A welding consumable.
308H (Grade): Indicates it's for 304H stainless steel, with high carbon content for creep resistance.
T (Tubular): It's a flux-cored wire.
1 (Position): Suitable for all welding positions (flat, horizontal, vertical, overhead).
-1 (Shielding Gas): Requires gas shielding, usually 100% CO or an Ar/CO mix.

Applications:

Welding Type 304H stainless steel.
Boilers, heat exchangers, and pressure vessels.
Chemical, food processing, and pharmaceutical industries.
High-stress, high-temperature service above 750F (399C).

Performance:

Excellent corrosion and oxidation resistance at high temperatures.
Smooth arc with low spatter.
Easy slag removal.
Good weld appearance.
