Product Description
BMS-321
MIG Welding Wire for Stainless Steel
Austenitic type
Compliance:
YB/T 5092 H06Cr19Ni10Ti
AWS A5.9 ER321
A5.9M ER321
EN ISO 14343-A: W 19 9 Ti
EN ISO 14343-B: SS321
Purpose
Often used in food processing, medical equipment, pressure vessels, petrochemical industry and other fields, such as welding 1Cr18Ni9Ti (SUS321) steel.
Characteristics
1. Thanks to the addition of Ti, the deposited metal has good resistance to intergranular corrosion and stable mechanical properties;
2. Smooth wire feeding, stable arc, good seam formation, excellent fluidity of molten metal, minimal spatter, excellent welding properties.
