Product Description
E316LT1-1 is a premium ultra-low carbon 18-12Mo2 austenitic stainless steel gas-shielded rutile flux-cored wire, fully compliant with AWS A5.22/A5.22M:2020 and GB/T 17853-2018 standards. With carbon content strictly controlled at ≤0.03% to prevent chromium carbide precipitation, and 2.0-3.0% molybdenum addition for enhanced corrosion resistance, it is engineered for all-position welding (flat, horizontal, vertical-up, vertical-down and overhead) using DC reverse polarity (DCEP). It is compatible with both 100% CO₂ and Ar-15-25% CO₂ mixed gas shielding, offering excellent adaptability to different welding equipment and site conditions. Typical deposited metal composition: 18.0-20.0% Cr, 11.0-14.0% Ni, 2.0-3.0% Mo, ≤2.0% Mn, ≤1.0% Si, ≤0.03% C, balance Fe.
Features
· Exceptionally stable and soft arc with instant ignition and excellent re-ignition capability, ideal for intermittent welding and tacking operations
· Extremely low spatter generation with fine, easily removable particles, drastically reducing post-weld grinding and cleaning time by up to 40%
· Beautiful weld bead appearance with uniform, fine ripples and excellent wetting characteristics, producing smooth, defect-free surfaces that require minimal finishing
· Self-peeling slag that removes completely even in vertical and overhead positions, leaving no residual slag inclusions
· Superior pitting and crevice corrosion resistance, excellent resistance to chloride ion attack and seawater corrosion
· Good low-temperature toughness, maintaining ductility down to -196°C (-321°F) for cryogenic applications
· Consistent mechanical properties: tensile strength 550-650 MPa, yield strength ≥400 MPa, elongation ≥30%, ensuring reliable structural integrity
· High deposition efficiency (up to 85%) and fast travel speed, significantly improving productivity compared to solid wires
Applications
Widely used for welding 316 and 316L austenitic stainless steels in corrosive environments.

FAQS
What is the primary use of E316LT-1?
It is primarily used for welding 316/316L stainless steels in applications requiring high corrosion resistance, especially in chemical, food processing, and marine environments.
What shielding gas is recommended?
100% CO₂ for deeper penetration and lower cost; 75% Ar/25% CO₂ for smoother arc and reduced spatter.
What is the difference between E316LT-1 and E308LT-1?
E316LT-1 contains 2-3% molybdenum for superior corrosion resistance in chloride environments, while E308LT-1 (without molybdenum) is designed for 304-type stainless steels.
