E307LT1-1 Stainless Steel Flux Cored Welding Wire
E307T1-1 stainless steel flux cored welding wire is an AWS A5.22-classified consumable for gas-shielded flux-cored arc welding. Its high-manganese austenitic weld metal is designed for selected difficult-to-weld materials, dissimilar-metal joints and applications requiring good resistance to weld cracking.
Key Features
- High-manganese austenitic weld metal.
- Designed for selected dissimilar-metal and difficult-to-weld applications.
- Suitable for certain high-strength steels and high-manganese steel applications, subject to procedure requirements.
- Can be considered for selected buffer-layer and repair applications.
- Available welding parameters and performance depend on the specific manufacturer's product.
Applications
E307T1-1 is a specialized stainless steel flux cored wire rather than a general-purpose filler for all stainless steel grades.
Typical application areas include:
- Selected high-manganese steel components.
- Certain dissimilar-metal joints between stainless steel and carbon or low-alloy steel.
- Selected high-strength steel fabrication and repair.
- Buffer layers before hardfacing where specified by the welding procedure.
- Industrial components exposed to impact, friction or work-hardening conditions, when the filler metal is approved for the application.
For critical structures, verify material compatibility, service conditions and the qualified welding procedure before use.
