DESCRIPTION | |||||||||||||||||||
NT·E91B3 is a gas-shielded and all-position flux-corded wire intended for 2.25%Cr-1%Mo low alloy steel welding. It should be used with 100%CO2 shielding gas and offers good operator appeal. SW·E91B3 is ideal for welding of Cr-Mo steel pipe and Cr-Mo steel, which need high creep resistance. | |||||||||||||||||||
APPLICATIONS | |||||||||||||||||||
The product is suitable for welding 2.5% Cr - 1% Mo low alloy heat-resistant steel (such as A335-P22 and A387Gr.22) with working temperature below 550℃. It is mainly used in the fields such as petroleum and petrochemical industry, high pressure vessel industry, steam pipeline industry and so on. | |||||||||||||||||||
