Metal & Flux Cored Wire
E410NiMoT1-1/-4 Stainless Steel Flux Cored Welding Wire
E410NiMoT1-1/-4 is a 410NiMo flux cored welding wire for 13Cr-4Ni martensitic stainless steel and ASTM CA6NM. Its Cr-Ni-Mo weld-metal system is suited to hydro turbine components, pumps, valves and repair welding where high strength and controlled heat treatment are required. It is designed for FCAW-G applications using CO₂ or Ar/CO₂ shielding gas.
E410NiMo for CA6NM Hydro Turbine Repair
E410NiMoT1-1/-4 is particularly suited to welding and repair of 13Cr-4Ni martensitic stainless steel, including CA6NM commonly used in hydroelectric equipment.
The wire is suitable for components exposed to water, mechanical loading and abrasive service, including:
- Hydro turbine components
- Hydraulic turbine repair
- CA6NM repair welding
- Pump components
- Valve components
- Shafts and heavy-section stainless parts
- 13Cr-4Ni stainless steel fabrication
For critical components, filler-metal selection and heat treatment should follow the qualified WPS and component specification.
E410NiMoT1-1 vs E410NiMoT1-4
Both classifications belong to the same E410NiMo weld-metal family. The main difference is the shielding gas.
Classification | Shielding Gas |
|---|---|
E410NiMoT1-1 | 100% CO₂ |
E410NiMoT1-4 | Typically 75–80% Ar + 20–25% CO₂ |
The exact gas composition should follow the manufacturer's technical data and qualified welding procedure.

Typical Weld Metal Composition
Element | AWS Reference (%) |
|---|---|
C | ≤0.06 |
Mn | ≤1.00 |
Si | ≤1.00 |
P | ≤0.04 |
S | ≤0.03 |
Cr | 11.0–12.5 |
Ni | 4.0–5.0 |
Mo | 0.40–0.70 |
Actual deposited weld-metal chemistry may vary with shielding gas, manufacturer and welding procedure.
Mechanical Properties
AWS Classification Requirements
Property | Requirement |
|---|---|
Tensile Strength | ≥760 MPa |
Elongation | ≥15% |
Commercial products may achieve tensile strengths around 890–900 MPa and elongation around 16–21%, depending on shielding gas and heat-treatment condition.
Actual properties should be confirmed from the manufacturer's test certificate.
Welding & Heat Treatment
E410NiMoT1-1/-4 is used with controlled heat input and appropriate preheat and interpass conditions.
For CA6NM and heavy-section hydro turbine components, controlled preheat and PWHT may be required depending on base material, thickness and the qualified welding procedure.
As a manufacturer reference, 1.6 mm wire may be used at approximately 160–220 A. Final current, voltage, preheat, interpass temperature and PWHT should follow the manufacturer's datasheet and qualified WPS.
