Product Description
BMS-309LMo
MIG Welding Wire for Stainless Steel
Austenitic type / For welding dissimilar steels
Compliance:
YB/T 5092 H02Cr24Ni13Mo2
AWS A5.9 ER309LMo
A5.9M ER309LMo
EN ISO 14343-A: G (23 12 2 L)
EN ISO 14343-B: SS309LMo
Purpose
Often used for welding dissimilar materials such as carbon steel to stainless steel, or for welding martensitic and ferritic stainless steels with low toughness; can also be used in the petrochemical industry, thermal power plants and other industries, for example, for surfacing transition metal on the inner wall of reactors.
Characteristics
1. The deposited metal has good mechanical properties and corrosion resistance;
2. Smooth wire feeding, stable arc, good seam formation, excellent fluidity of molten metal, minimal spatter, excellent welding properties.
