ER410NiMo falls under the classification of **AWS A5.9 / ASME SFA 5.9** as a stainless filler metal. It’s a martensitic/martensitic-ferritic stainless alloy that contains approximately **11.0‑12.5% Chromium (Cr)**, **4.0‑5.0% Nickel (Ni)**, and **0.4‑0.7% Molybdenum (Mo)**. Carbon content is kept to a maximum of ~0.06% to manage hardening and enhance toughness. Additionally, trace amounts of elements like manganese (Mn), silicon (Si), phosphorus (P), sulfur (S), and copper (Cu) are included (Mn ≤ 0.60%, Si ≤ 0.50%, P, S ≤ 0.03%, Cu up to ~0.75%).
When applied through MIG or TIG processes, ER410NiMo yields weld metal that boasts high strength and decent toughness. You can expect typical tensile strength values around **118,000 psi (≈ 810 MPa)**, with yield strengths hovering around **92,000 psi (≈ 635 MPa)**. Elongation is generally about **20%** in many instances. The hardness of the weld deposit tends to be on the higher side due to the martensitic phase, so it’s advisable to preheat and control interpass temperatures (at least ~300 °F / 150 °C) to prevent cracking. Also, post-weld heat treatment (PWHT) should not exceed ~ 1150 °F (≈ 620 °C), as higher temperatures could result in over-hardening or a reduction in toughness.
