R307

Compliant with GB E5515-B2
Equivalent to AWS E8015-B2

Instructions:R307 is a low hydrogen sodium coating pearlite heat-resistant steel welding rod containing Cr1% - Mo0.5%. It adopts DC reverse connection and can be welded in all positions. The welded parts should be preheated and post weld heat treated appropriately according to the structural characteristics.

Purpose:Used for welding Cr1% - Mo0.5% heat-resistant steel with a working temperature below 520 ℃, such as boiler pipes, high-pressure vessels, petroleum refining equipment, etc. It can also be used for welding 30CrMoSi cast steel parts.
