Product Description
BGS-312
TIG Welding Wire for Stainless Steel
Austenitic type / For welding dissimilar steels
Compliance:
YB/T 5092 H12Cr30Ni9
AWS A5.9 ER312
A5.9M ER312
EN ISO 14343-A: W (29 9)
EN ISO 14343-B: SS312
Purpose
Often used for welding dissimilar materials, such as carbon steel to stainless steel, or for a transition layer back-weld, and can also be used for dissimilar joints between ferritic and austenitic steels and for surfacing steel.
Characteristics
1. The weld metal has good dilution resistance, ferrite content reaches 30%, excellent hot cracking resistance;
2. Stable arc, good weld formation, excellent fluidity of molten metal, excellent welding properties.
