AWS A5.9M ER309L
EN ISO 14343-A: W (23 12 L)
EN ISO 14343-B: SS309L
JIS Z3321 YS309L
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, as well as for surfacing a transition layer on the inner wall of reactors.
Characteristics
1. The deposited metal has good mechanical properties and corrosion resistance;
2. Stable arc, good weld formation, excellent fluidity of molten metal, excellent welding properties.
