Product Description
BMS-308LT
MIG Welding Wire for Stainless Steel
Austenitic / Ultra Low Temperature
Compliance:
YB/T 5092 H022Cr21Ni10
AWS A5.9 ER308L, A5.9M ER308L
EN ISO 14343-A: G (19 9 L)
EN ISO 14343-B: SS308L
Purpose
Suitable for welding equipment in industries such as the petrochemical industry, pressure vessel manufacturing, food processing, medical equipment, as well as for welding low-temperature tanks, vessels and other equipment operating at temperatures down to -196 °C, such as SUS304L steel and similar.
Characteristics
1. Basic chemical composition: 20% Cr - 9% Ni;
2. The weld metal has good mechanical properties and corrosion resistance, and excellent low-temperature toughness at -196°C;
3. Smooth wire feeding, stable arc, good seam formation, excellent fluidity of molten metal, minimal spatter, excellent welding properties.
