Product Description

Characteristics: 

( 1 ) The product is 9Cr-1Mo Cr-Mo heat resistant steel MIG welding wire.

( 2 ) It’s used to weld 9%Cr-1%Mo-Nb-V heat resistant steel,the molten metal has excellent high temperature strength, toughness, fatigue life, oxidation resistance and corrosion resistance.


Precautions:

( 1 ) Adequately clear the oil,rust,moisture,dust and other debris of the welded parts.

( 2 ) The hardening capacity of molten metal is strong in air-cool,it need preheat before welding and heat treatment after welding.

( 3 ) Preheat and interpass temperature in 160~190℃,heat treatment after welding in 840~870℃.
