SELECTARC INOX 308HB - Basic-coated high carbon stainless steel electrode 

CLASSIFICATION

AWS A5.4: E308H-15ISO 3581-A: E 19 9 H B 4 2

DESCRIPTION AND APPLICATION

SELECTARC INOX 308HB is an austenitic stainless steel electrode with a basic-type coating containing approximately 5% ferrite and an increased carbon content. This electrode provides excellent mechanical properties and high strength under elevated temperature conditions.

It is specifically designed for 18/8-type (304H-type) stainless steels operating at high service temperatures up to +750 °C. Thanks to its coating composition, the electrode ensures a stable and uniform welding arc, easy slag removal, and a smooth weld bead profile.

Suitable for use in the oil and gas industry, chemical processing, and the energy sector, including welding of pipes, tanks, heat exchangers, and pipeline systems.
