Stainless Steel Wire 1.6mm
Ultra-low carbon (C≤0.03%) minimizes intergranular corrosion, ideal for high-temperature and corrosive environments.
Optimized Cr/Ni content (Cr 19.5-22.0%, Ni 9.0-11.0%) ensures resistance to acids and oxidation.
ER308L(HSi) Stainless Steel TIG Wire: Properties, Global Standards & Performance Comparison
Key Features
ER308L(HSi) is an ultra-low carbon silicon-enhanced stainless steel TIG wire, designed for welding 304L (022Cr19Ni10) austenitic stainless steel
Superior Corrosion Resistance
Ultra-low carbon (C≤0.03%) minimizes intergranular corrosion, ideal for high-temperature and corrosive environments.
Optimized Cr/Ni content (Cr 19.5-22.0%, Ni 9.0-11.0%) ensures resistance to acids and oxidation.
Excellent Weldability
Silicon addition (Si 0.65-1.00%) enhances fluidity, producing smooth beads with minimal spatter.
Stable arc performance for all-position welding; recommended current: 50-400A (varies by diameter).
Reliable Mechanical Properties
Tensile strength ≥520MPa, elongation ≥35%, suitable for high-stress applications.
