Product Description
BMS-316LSi
MIG Welding Wire for Stainless Steel
Austenitic type
Compliance:
YB/T 5092 H022Cr19Ni12Mo2Si
AWS A5.9 ER316LSi
A5.9M ER316LSi
EN ISO 14343-A: G (19 12 3 L Si)
EN ISO 14343-B: SS316LSi
JIS Z3321 YS316LSi
Purpose
Suitable for welding in petrochemical industry, pressure vessel industry, low temperature tank industry, fertilizer and urea equipment, food processing industry and other industries, for welding 18Cr-12Ni-2Mo type stainless steel (such as SUS316L).
Characteristics
1. The deposited metal has good mechanical properties and stable heat resistance;
2. Thanks to the addition of Mo, the high-temperature creep resistance and pitting corrosion resistance in halide-containing environments are improved;
3. Thanks to the addition of Si, it has excellent fluidity of the molten metal, better weld formation, minimal spattering and excellent welding properties.
