Stainless Steel Welding Wire GJ-ER410

Copper-Free Solid Wire
(13Cr martensitic stainless)

  • AWS A5.9 ER410
  • EN ISO 14343-A-G 13

Product description

GJ-ER410 is a 13% chromium martensitic stainless steel solid wire strictly complying with AWS A5.9 ER410. It produces a martensitic weld metal with high hardness and wear resistance, designed for welding 410 stainless steel and for surfacing applications requiring abrasion resistance.

Key Advantages

  • 01GUJIN

    High Hardness & Wear Resistance: 13Cr martensitic weld metal achieves 35-40 HRC in the as-welded condition, providing excellent abrasion resistance.

  • 02GUJIN

    Tunable Properties: Hardness can be adjusted via post-weld heat treatment (22-28 HRC after tempering at 650-750C) for improved toughness.

  • 03GUJIN

    Good Corrosion Resistance: 11.5-13.5% chromium provides moderate corrosion resistance for mild atmospheric and aqueous environments.

Application Guide

  • With Ar+2%O2 shielding: For welding 410/420 stainless in turbine blades, valve seats, pump components, and cutlery.

  • With 100% Ar (TIG): For repair welding of martensitic stainless castings and for hardfacing of carbon steel components requiring wear resistance.

  • For surfacing: Suitable for single-layer surfacing of carbon steel to provide corrosion and abrasion-resistant surfaces in mild environments.

FAQ

How do you prevent the agglomerated flux from absorbing moisture during long-distance sea freight?

Moisture control is critical for submerged‑arc welding fluxes. Our standard packaging is 25‑kilogram multi‑layer kraft paper bags lined with heavy‑duty moisture‑proof plastic bags. For extreme environments or ultra‑low hydrogen requirements (such as H5 grade), we can also provide custom heavy‑duty aluminium foil vacuum packaging. All goods are stacked on wooden pallets and tightly wrapped with multiple layers of industrial shrink film to ensure 100% dryness upon arrival at the port.

We are fabricating API 5L X70 pipes. Can we use standard neutral fluxes like GJ-301?

No. For High-Grade Oil & Gas pipeline fabrication (such as API X60 to X70), standard neutral fluxes like 301 or active fluxes like 501 are not suitable, as they cannot guarantee the required extreme low-temperature impact toughness. You must use our dedicated pipeline-grade Fluoride-Basic agglomerated flux, GJ-101Q (or GJ-101G), combined with Mo/Ni-alloyed wires (e.g., EA2 or S3Ni1Mo).This combination ensures zero loss of alloying elements and guarantees impact values of ≥27J(or much higher) at -40°C to -50°C.

What is your minimum order quantity (MOQ) and typical delivery time for a 20ft container?

Our standard MOQ for international orders is normally 5 tons per item. For a full 20‑foot FCL container, the loading capacity is usually 24 tons subject to container space constraints, and it can reach 27 tons without pallets. A 40HQ high‑cube container can hold a maximum of 28 tons. Backed by our robust production capacity, we can finish production, quality inspection and packaging within 7‑10 days upon receiving the deposit, and deliver the goods to major Chinese ports such as Qingdao Port or Tianjin Port.

Our workshop wants to save time and energy. Is there a way to use the agglomerated flux directly without the re-baking process?

Yes! We fully understand that re-baking costs time and electricity. For customers who want to skip this step, we highly recommend selecting our Heavy-Duty Aluminum Foil Vacuum Packaging. The flux is vacuum-sealed immediately after high-temperature manufacturing. When you open the bag in your workshop, the flux is in a 100% factory-dry state and can be poured directly into the welding hopper for immediate use.

Our steel plates have light rust and mill scale, and we cannot perfectly sandblast all of them before welding. Which flux can prevent porosity in this situation?

For structural steel with surface impurities like rust, oil, or mill scale, standard neutral or high-basic fluxes will likely cause porosity. You need our GJ-501A (Aluminate-Rutile Active Flux). It features a highly active deoxidizing slag system that offers exceptional tolerance to surface contaminants. This allows you to achieve flawless, X-ray quality welds at high speeds without rigorous pre-weld grinding, significantly boosting your shop floor efficiency.
