Product Description
BMS-2594
MIG Welding Wire for Stainless Steel
Austenitic-ferritic duplex type
Compliance:
YB/T 5092 H022Cr25Ni9Mo4N
AWS A5.9 ER2594
A5.9M ER2594
EN ISO 14343-A: G 25 9 4 N L
EN ISO 14343-B:SS2594
Purpose
Suitable for welding 25% Cr duplex stainless steels in the petrochemical and marine industries, such as SUS2507 and similar.
Characteristics
1. Because the weld metal contains about 40% ferrite and combines the comprehensive properties of austenitic and ferritic stainless steels, the pitting resistance equivalent index PRE ≥ 40, which provides excellent resistance to pitting corrosion and stress corrosion cracking;
2. Smooth wire feeding, stable arc, good seam formation, minimal spatter, excellent welding properties.
