308LT1-1 Flux Cored Welding Wire

308LT1-1 Stainless Steel Flux Cored Welding Wire for Corrosion & Abrasion Resistance

308LT1-1 flux cored welding wire is a rutile type, gas-shielded stainless steel FCAW wire developed for welding austenitic stainless steels where corrosion resistance, abrasion resistance, and weld integrity are critical. Manufactured in compliance with AWS A/SFA 5.22 308LT1-1 and EN ISO 17633-A, this wire ensures smooth arc performance, consistent mechanical properties, and high-quality weld deposits.

It is widely used in hygienic, chemical, marine, and pressure equipment applications, where reliability and metallurgical stability are essential.

308LT1-1 Welding Wire Classification & Standards

The 308LT1-1 flux cored welding wire conforms to the following international classifications and approvals:

EN ISO 17633-A classification T 23 12 LRC/M 1

TS classification TS308LT1-1

AWS A/SFA 5.22 classification 308LT1-1

BIS approved

These standards confirm the wire’s suitability for stainless steel fabrication in critical service environments.

Typical Chemical Composition of 308LT1-1 Weld Metal

The undiluted weld metal chemistry of 308LT1-1 FCAW wire is optimized for corrosion resistance and mechanical stability. Typical composition includes approximately 0.03% Carbon, 1.80% Manganese, 0.50% Silicon, 19.50% Chromium, and 10.20% Nickel.

This balanced austenitic stainless steel chemistry provides excellent resistance to corrosion, oxidation, and wear, along with stable microstructure and crack resistance.

Mechanical Properties of 308LT1-1 Flux Cored Welding Wire

In the as-welded condition, 308LT1-1 welding wire produces weld metal with a typical ultimate tensile strength of around 570 MPa and a yield strength of approximately 420 MPa at 0.2% offset. The weld metal exhibits good elongation of about 28% and maintains reliable impact toughness at room temperature, ensuring durability under service conditions.

These properties make the wire suitable for pressure-containing and load-bearing stainless steel structures.

Recommended Welding Parameters for 308LT1-1 FCAW Wire

The 308LT1-1 flux cored welding wire is available in 1.2 mm and 1.6 mm diameters. The recommended amperage range is approximately 130 to 280 amperes for 1.2 mm wire and 200 to 360 amperes for 1.6 mm wire. Welding should be performed using DCEP (Electrode Positive).

This wire is suitable for welding with CO₂ or Argon-CO₂ mixed shielding gas. When using mixed shielding gas, it is recommended to reduce the voltage by 1 to 2 volts to achieve optimal arc stability and bead profile.

Packing Details of 308LT1-1 Flux Cored Welding Wire

The wire is supplied in 15 kg vacuum-sealed packs, layer wound on high-strength plastic spools. Vacuum packing prevents moisture absorption, ensuring stable wire feeding, consistent arc performance, and long shelf life.
