AK-E316LT1-1 Rutile Flux-Cored Wire for All-Position Stainless Steel Welding.
A flux-cored wire for welding SUS316L and similar stainless steels with stable performance, consistent mechanical properties, and strong resistance to heat and corrosion.
Product Overview
AK-E316LT1-1 is a rutile-type flux-cored wire for manual and semi-automatic gas-shielded metal arc welding of stainless steels. It is designed for all-position welding and delivers consistent mechanical properties in the deposited metal.
The wire is suitable for welding SUS316L steel and is commonly used in applications requiring high resistance to heat and corrosion, such as urea equipment, fertilizer systems, synthetic fiber plants, petrochemical storage tanks, and critical structural components.
Application: Suitable for SUS316L steel, mostly used for welding urea, fertilizer, synthetic fiber, petrochemical or important structures of storage equipment, etc.
Key Benefits
All-Position Welding Capability
AK-E316LT1-1 can be used in flat, horizontal, vertical, and overhead positions, allowing a single wire to cover multiple joint orientations without changing consumables.
Stable Welding Performance
The rutile flux formulation ensures a stable arc and consistent weld pool behavior, reducing spatter and improving weld bead appearance across the recommended current ranges.
Excellent Heat and Corrosion Resistance.
The deposited metal exhibits strong resistance to heat and corrosion, meeting the requirements for service in aggressive environments such as chemical processing and storage equipment.
Consistent Mechanical Properties
The mechanical properties of the deposited metal are stable and repeatable, supporting reliable weld performance in critical applications.
Where It Is Used
- Welding of SUS316L stainless steel in chemical and petrochemical plants.
- Fabrication and repair of urea and fertilizer equipment.
- Construction of synthetic fiber production systems.
- Welding of storage tanks and pressure vessels in corrosive service.
- Critical structural joints in industrial plants requiring high corrosion resistance.
Who It Is For
- Welding consumable distributors supplying flux-cored wires for stainless steel applications.
- Petrochemical and chemical plant fabricators working with SUS316L and similar grades.
- Maintenance teams responsible for repairing corrosion-resistant equipment in harsh environments.
- Fabricators of storage and processing equipment requiring consistent weld quality.
Problems It Solves
- Matching filler metal chemistry to SUS316L base metal to ensure the weld metal meets the required corrosion and heat resistance standards.
- Achieving consistent mechanical properties in the deposited metal across multiple welds and operators.
- Using a single wire that performs reliably in all welding positions without requalification or parameter changes.

How It Compares
AK-E316LT1-1 is a rutile-type flux-cored wire suitable for all-position welding of SUS316L. It provides good arc stability and clean weld beads. Compared to basic flux-cored wires, it has higher spatter and lower hydrogen content, but offers easier handling and better deposition efficiency. It is not intended for use where ultra-low hydrogen levels are required. For applications demanding maximum corrosion resistance in highly aggressive environments, a higher alloyed or low-carbon variant may be considered.
