Product Description

Characteristics: 

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

( 2 ) The molten metal contains 1.25%Cr- 0.5%Mo alloy content,it’s used to weld similar content alloy steel.

( 3 ) It’s used to weld pearlitic heat resistant steel under 520oC working temperature, such as boiler pipe, high pressure vessel, oil refining equipment, etc.


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 135~165℃,heat treatment after welding in 675~705℃.
