Product Description
BGS-2209
TIG Welding Wire for Stainless Steel
Austenitic-ferritic duplex type
Compliance:
YB/T 5092 H022Cr22Ni9Mo3N
AWS A5.9 ER2209
AWS A5.9M ER2209
EN ISO 14343-A: W (22 9 3 N L)
EN ISO 14343-B: SS2209
Purpose
Suitable for petrochemical welding of duplex stainless steels containing 22% Cr such as 00Cr22Ni5Mo3N (SUS2205).
Characteristics
1. Main chemical composition: 22%Cr-9%Ni-3%Mo-N;
2. The weld metal contains about 40% ferrite, and combines the comprehensive properties of austenitic and ferritic stainless steels, has excellent resistance to pitting corrosion and stress corrosion cracking;
3. Stable arc, good seam formation, excellent welding properties.
