410 Stainless Steel Sheet
410 stainless steel sheet is a martensitic alloy sheet celebrated for its high strength, excellent hardenability, and cost-effectiveness-distinguishing itself from austenitic grades like 316L. With a chromium content of 11.5-13.5% and moderate carbon (≤0.15%), it offers reliable corrosion resistance in mild environments while delivering superior mechanical strength after heat treatment. Its martensitic structure also grants inherent magnetic properties, making it a preferred choice for industrial, automotive, and hardware applications where strength, magnetism, and budget balance are key.
Core Traits of 410 Stainless Steel Sheet
High Strength & Hardenability
Through heat treatment (quenching and tempering), it achieves tensile strength up to 860 MPa-far exceeding austenitic grades like 316L-ideal for load-bearing or wear-resistant components.
01
Chromium-Enhanced Corrosion Resistance
The 11.5-13.5% chromium content forms a protective oxide layer, resisting rust and oxidation in dry to moderately humid environments (e.g., indoor industrial settings, non-salty outdoor areas).
02
Inherent Magnetic Property
As a martensitic alloy, it is strongly magnetic-suitable for applications requiring magnetic adsorption, such as sensor brackets, magnetic fasteners, and industrial fixtures.
03
Cost-Effective Performance
Offers a more budget-friendly alternative to 304 or 316L for non-severe corrosion scenarios, without compromising on strength or processability.
04
Good Fabricability
While harder than austenitic sheets, it retains decent ductility for cutting, bending, and stamping-adaptable to thin-gauge parts like automotive trim and hardware components.

Processing Guidelines for Sheet
- Heat Treatment
Quenching (heating to 920-980°C, water cooling) followed by tempering (200-700°C) enhances hardness and strength-critical for wear-resistant parts like cutting blades or valve components.
Annealing (heating to 815-900°C, slow cooling) softens the sheet for easier forming and machining, ideal for complex shapes.
- Welding & Forming
Weldable via TIG or MIG methods, but post-weld annealing is recommended to reduce brittleness and restore corrosion resistance in heat-affected zones.
Supports cold forming (bending, stamping) for thin gauges; avoid excessive deformation to prevent cracking-ideal for automotive trim or hardware brackets.
Typical Application Scenarios
- Automotive Industry
Exhaust shields, fuel tank caps, and door hinges-leveraging high strength and moderate corrosion resistance to withstand road conditions.
- Industrial Hardware
Fasteners (screws, bolts), cutting blades, and tool holders-benefiting from heat-treated hardness and wear resistance.
- Appliance Components
Oven door hinges, dryer drum parts, and small electric motor housings-using magnetic properties for assembly and moderate heat resistance.
- General Fabrication
Sensor brackets, magnetic signage, and light structural parts-balancing cost, strength, and magnetism for industrial use.
