E309LT1-1 Stainless Steel Flux Cored Welding Wire Made In China
Core Function: To create a high-alloy, austenitic weld deposit that can tolerate significant dilution from dissimilar or lower-alloy base metals without forming martensitic structures or cracking. It serves as a "buffer" or "transition" alloy.
Primary Applications:
Dissimilar Metal Welding (DMW):
Stainless Steel (304, 304L, 316, etc.) to Mild or Low-Alloy Steel (e.g., joining a stainless pipe to a carbon steel flange).
Joining 304L to 409 or 410 stainless (ferritic/martensitic grades).
Cladding & Overlay (Hardfacing):
Applying a corrosion-resistant stainless layer onto carbon steel rolls, vessels, or machinery parts.
Welding Higher Alloy Steels:
Repair or fabrication of 309/309S stainless steel components.
Welding 321 & 347 stainless for certain applications, though these grades ideally use Nb-stabilized fillers.
High-Temperature Service:
Components exposed to cyclic heating and cooling where oxidation resistance is critical.
Material Compatibility (Typical Base Metals):
Primary for: 304/304L/308 to Carbon Steel joints.
Also used for: 309/309S base metal, 316 to carbon steel, and for overlays on carbon steel.

Q1: Can I have a sample for testing?
A: Yes, we can support free sample.
Q2: Can I add my logo on the boxes/cartons?
A: Yes, OEM and ODM are available from us,for the MOQ for OEM/ODM talk with us please.
Q3: What are the benefits of being a distributor?
A: Special discount Marketing protection.
Q4: Do you have inspection procedures for welding wires and welding electrode?
A: 100% self-inspection before packing. We provide Quality Certification for every order.
Q5: Can we mix itmes in one 20FT container?
A: Yes,welding wire and welding electrode can mix them in one container.
Q6: Can I have a visit to your factory before the order?
A: Sure, welcome your visit of factory, or we can have a online meeting for factory inspection.
Q7: What is the lead time for samples and mass production?
A: Samples can be ready within 3-5 working days. For mass production, it usually takes 15-25 working days, depending on the order quantity and customization requirements.
Q8: What payment terms do you accept?
A: We accept T/T (30% deposit in advance, 70% balance against B/L copy), L/C at sight, and Western Union for small orders. Other terms can be negotiated for long-term cooperation.
