AWS E310-16

Description and Applications

HE310 is a lime-Titania type electrode. Deposited metal contains about 25% Cr and 20% Ni. Mechanical properties are excellent. It provides good corrosion resistance and heat resistance in as-welded condition.

Welding of stainless steel 310, Cr-Mo steel, 13Cr steel.

 

Guideline in Usage

1.

Electrodes should be re-dried at 250 300℃ for one hour before use.

2.

Keep arc and amperage as short and low as possible.  Remove dirt such as oil and dust from the groove.

3. Sufficient crater treatment is required since deposited metal is a completely austenitic structure and crack resistance is slightly low.
4.

Keep the interpass temperature under 150℃.
