JIS : Z3321 YS308L
EN : 14343-A G 19 9 L Si
GB : T 5092 H03Cr21Ni10Si1
Shielding Gas: AR + 1~2%O2 AR+ 1~2%CO2
Applications & Features
1. Weld metal is austenite structure with 20% Cr- 9% Ni
2. It provides good weldability and puddle fluidity
3. It has good crack and corrosion resistance due to its moderate ferrite content.
4. It is suitable for welding thin plate of 18% Cr-8% Ni stainless steel with high travel speed such as AISI 301, 302, 303, 304L and 308 steel
Welding Instruction
1. Use Ar blend with 1~2% O2 for high current spray transfer welding
2. Use Ar blend with 1~2% CO2 for low current , short-circuit transfer welding
