E308LT1-1 Flux Cored Welding Wire For 304/304L Stainless Steel
Products Description
E308LT1-1 is a gas-shielded flux cored welding wire designed for 304 and 304L austenitic stainless steels. It provides a stable arc, low spatter, and smooth metal transfer. The weld metal offers good corrosion resistance and mechanical properties, while the rutile-based flux ensures easy slag removal. We supply this wire directly from our factory, offering competitive pricing, full quality traceability (MTC provided), and flexible spool sizes (1kg, 5kg, 15kg) to meet your project needs.
Key Features
1. Superior Crack Resistance: Specially formulated to effectively prevent solidification cracking in 304/304L stainless steel welds.
2. Excellent Fluidity and Arc Stability: Ensures smooth metal transfer and adequate penetration with minimal spatter.
3. Aesthetic Weld Appearance: Produces clean, uniform welds with a smooth, ripple-free surface and easy slag removal.
4. All-Position Welding: Highly versatile, supporting flat, horizontal, vertical, and overhead welding positions (FCAW-G).
5. Factory-Direct Pricing: Eliminates middlemen to maximize cost savings while ensuring compliance with AWS/ISO quality standards.
6. Global Shipping: Offers fast, reliable worldwide delivery using robust, moisture-proof packaging to ensure the welding wire arrives in perfect condition.

Typical Applications
- Food and Beverage Processing: Used for dairy storage tanks, brewing vessels, and food-grade piping; low carbon content prevents chromium carbide precipitation, ensuring compliance with strict hygiene standards and providing excellent corrosion resistance.
- Chemical and Petrochemical Industries: Used for storage tanks, reactors, and heat exchangers handling mildly corrosive media at moderate temperatures.
- Construction and Structural Fabrication: Used for handrails, decorative panels, and structural frameworks; produces aesthetically pleasing welds with minimal post-weld grinding required.
- Pressure Vessels and Marine Components: Suitable for applications requiring reliable impact toughness and resistance to atmospheric corrosion (or mild chloride corrosion).
- General Manufacturing and Maintenance: Used for the high-speed, all-position welding and repair of 304/304L stainless steel mechanical parts, automotive exhaust system components, and transport containers.
FAQ
Q1: What are the main advantages of E308LT1-1 compared to solid ER308LSi MIG wire?
A: E308LT1-1 offers higher deposition rates, deeper penetration, and greater tolerance for minor surface scale or rust. Its flux-cored composition also provides more stable arc characteristics (greater operational latitude) during all-position welding, although post-weld slag removal is required.
Q2: Does this wire require a shielding gas, or is it self-shielding?
A: E308LT1-1 falls under the "T1-1" classification, meaning it is a gas-shielded flux-cored wire (FCAW-G). It requires an external shielding gas (typically 75–80% Argon / 20–25% CO2) to protect the weld pool from atmospheric contamination.
Q3: How should the wire spools be stored to maintain quality?
A: Store in a dry, well-ventilated environment at room temperature. Keep the vacuum-sealed packaging intact until use. If the packaging is damaged or the wire has been exposed to high humidity, bake the spool at 150°C for 1–2 hours before use to prevent porosity.
Q4: Do you provide quality certification for bulk orders?
A: Yes. Every batch is manufactured under a strict ISO 9001 quality control system. We provide a detailed EN 10204 3.1 Material Test Certificate (MTC) with every shipment, listing the actual chemical composition and mechanical property test results.
