Product Description

Characteristics: 

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

( 2 ) The molten metal contains9%Cr-1%Mo alloy content,it’s used to weld similar content alloy steel.

( 3 ) It’s used to weld high the heat resistant steel of temperature and high pressure equipment, such as ASTM A219-T9、A385-P9


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 177~232℃,heat treatment after welding in 840~870℃.
