RATNA 308H (AWS A5.4 E308H-16)

An electrode specially designed for producing 19Cr-10Ni weld deposit with carbon 0.04- 0.08%

Classification:

AWS/SFA-5.4: E 308H-16
IS-5206: E 19.9R 26

Characteristics:

An electrode specially designed for producing 19Cr-10Ni weld deposit with carbon 0.04- 0.08%, weld metal is resistant to crack and exhibits excellent mechanical properties at elevated temperature. The weld produced are of radiographic quality with smooth bead finish.

Application:

Suitable for joining AISI 304H material used in high temperature applications (730°C).
Ideally suitable for joining 18/8 SS consisting of higher carbon percentage.
Chemical, petrochemical and refinery equipments.

Re-Dry Condition:

Re-Dry the electrode at 250°C for 1 hrs before use.
