Grade 410, martensitic stainless steel

410 Stainless Steel Coil and Sheet

A corrosion- and heat-resistant martensitic stainless steel with about 12% chromium. Heat treatment gives it a wide range of mechanical properties, with high hardness and strength for wear-prone uses such as cutlery, kitchen utensils and hand tools.

Why choose 410 stainless steel?

Hardness and strength, raised further by heat treatment.

High hardness and strength

Hard and strong as supplied, for tools, valves and mechanical parts.

Hardenable

Heat treatment raises its hardness and strength further.

Magnetic

Martensitic, so it is magnetic, unlike austenitic grades such as 304. Widely used for kitchen appliances and equipment.

Corrosion, heat and the shop floor.

How 410 behaves in service and in fabrication.

Corrosion resistance

Good in mild environments. 410S, with less carbon, is slightly better.

Heat resistance

Withstands service temperatures up to about 650 °C.

Machining

Machines well when annealed: drilling, milling, turning and tapping. Machinability falls as hardness rises; use sharp tools and suitable speeds.

Welding

Possible with care: preheat to 150–260 °C (300–500 °F), then post-weld heat treat to relieve stress and restore ductility. SMAW, TIG and MIG all work.

Hot working

870–1200 °C (1600–2200 °F), by forging, hot rolling or extrusion.

Annealing

About 760–870 °C (1400–1600 °F), then slow, controlled cooling, to soften it and improve machinability and formability.

Hardening

Heat to 925–1010 °C (1700–1850 °F) and quench in oil or air.

Tempering

About 150–370 °C (300–700 °F) to adjust hardness and improve toughness.

410 or another grade?

How 410 compares with 304, 416 and 410S.

410 vs 304

410 is martensitic: stronger and harder, with lower corrosion resistance. 304 is austenitic: better corrosion resistance, toughness and weldability. 410 suits tools and valves; 304 suits kitchenware, food equipment and architecture.

304

410 vs 416

Both are martensitic. 416 has added sulfur for much better machinability, so it suits screws and precision-machined fittings; 410 suits hard, strong parts such as knives and mechanical components.
