AK-H13CrMoA Submerged Arc Welding Wire for 1%Cr-0.5%Mo Heat-Resistant Steel.
A pearlitic heat-resistant steel welding wire formulated for use with fluxes like SJ101 and HJ250 to produce weld metal with strong mechanical properties in high-temperature service environments.
Product Overview
AK-H13CrMoA is a 1%Cr-0.5%Mo pearlitic heat-resistant steel submerged arc welding wire designed for joining 1%Cr-0.5%Mo base metals such as 15CrMo and 12CrMo steels used in pipeline and structural applications.
When used with compatible fluxes like SJ101 or HJ250, it delivers weld metal with excellent mechanical properties, including high tensile strength and impact toughness at low temperatures, meeting the requirements of the EN ISO, AWS, and GB/T 12470 F55P2-H13CrMoA standards.
Application: With flux (such as SJ101, HJ250), it is used for welding 1%Cr-0.5%Mo pearlitic heat resistant steel, such as 15CrMo and 12CrMo steel of heat-resistant st eel pipeline structure.
Key Benefits
High Tensile Strength and Yield Stress.
The weld metal achieves a tensile strength of 550-700 MPa and a yield stress of at least 470 MPa, ensuring structural integrity under high-stress conditions.
Good Ductility and Toughness.
With elongation of at least 20% and impact energy of at least 27 J at minus 20 degrees C, the weld metal resists cracking and maintains performance in low-temperature environments.
Controlled Chemical Composition
The wire's composition—C 0.11-0.18%, Si 0.15-0.35%, Mn 0.40-0.70%, Cr 0.80-1.10%, Mo 0.40-0.60%, and impurities S and P ≤0.030%—ensures consistent metallurgical performance and compatibility with specified base metals.
Compatibility with Standard Fluxes.
It is recommended for use with fluxes such as SJ101 and HJ250, which are widely used in industrial welding of heat-resistant steel structures.
Where It Is Used
- Welding of 1%Cr-0.5%Mo pearlitic heat-resistant steel pipelines.
- Structural welding in power plant and petrochemical facilities.
- Repair and fabrication of 15CrMo and 12CrMo steel components exposed to elevated temperatures.
- Submerged arc welding in automated and semi-automated production lines.
Who It Is For
- Welding consumable distributors supplying heat-resistant steel welding solutions.
- Fabricators working with 15CrMo and 12CrMo steel in pipeline and pressure equipment.
- Maintenance teams in power and petrochemical industries requiring reliable weld metal performance.
Problems It Solves
- Matching filler metal chemistry to 1%Cr-0.5%Mo base metals to ensure weld metal properties meet code requirements, not just nominal composition.
- Achieving consistent mechanical properties in weld metal through controlled wire composition and flux pairing.
- Reducing the risk of weld failure in high-temperature service by using a wire with verified impact toughness at minus 20 degrees C.

How It Compares
AK-H13CrMoA is a 1%Cr-0.5%Mo submerged arc welding wire intended for heat-resistant steel applications. It differs from general-purpose mild steel wires by its specific alloying elements and mechanical property targets. It is not suitable for low-alloy or non-heat-resistant steels. When compared to other heat-resistant wires, its composition and performance are tailored to 15CrMo and 12CrMo base metals, ensuring compatibility and code compliance.
