Product Description

Characteristics: 

( 1 ) The product is 2.25Cr-1Mo Cr-Mo heat resistant steel MIG welding wire.

( 2 ) It’s used to weld similar content pearlitic heat resistant steel, the pipe of boiler heating surface under 580oC working temperature and high temperature and high pressure pipe, synthesis of chemical machinery ,oil cracking Equipment, etc, under 550oC working temperature.


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℃.
