AISI 410 Stainless Steel Foil/Sheet
Available Configurations
Properties common to all products in this list
Key Features
AISI 410 Stainless Steel Foil (UNS S41000) is a martensitic chromium stainless steel foil with 11.5-13.5% chromium and a carbon content of up to 0.15 wt%, delivering high hardness and wear resistance after heat treatment alongside moderate corrosion resistance in mildly corrosive, dry, or atmospheric environments:
High Hardness & Wear Resistance After Heat Treatment
AISI 410 Foil delivers high hardness and wear resistance after heat treatment, with quenching and tempering raising hardness substantially from the soft, formable annealed condition.
Soft Enough for Precision Forming in the Annealed Condition
In the annealed condition AISI 410 Foil is soft enough for precision forming and rolling, allowing complex geometries to be produced before quench-and-temper treatment locks in the final hardness.
Moderate Corrosion Resistance
Moderate corrosion resistance in mildly corrosive, dry, or atmospheric environments supports use of AISI 410 Foil in applications where wear resistance is the primary requirement and environmental exposure is limited.
Elevated-Temperature Oxidation Resistance
Elevated-temperature capability and resistance to oxidation in low-sulfur, non-halide environments support applications in aerospace, chemical processing, and automotive exhaust systems.
Dimensional Stability in Thin Section
AISI 410 Foil maintains dimensional stability in thin section, making it useful for applications requiring wear resistance and consistent geometry such as precision shims and instrumentation substrates.
Industrial Applications
AISI 410 Stainless Steel Foil is used across aerospace, chemical processing, and automotive sectors where wear resistance and dimensional stability are required in thin section:
- ✦ Precision Shims & Wear-Resistant Formed Components
- Used as precision shims and wear-resistant formed components in mechanical assemblies, where high hardness after heat treatment combined with dimensional stability in thin section ensures reliable, repeatable performance.
- ✦ Catalyst Carriers in Emission Control Systems
- Formed into catalyst carriers for emission control systems, where elevated-temperature capability and resistance to oxidation in low-sulfur, non-halide environments support reliable long-term operation.
- ✦ Precision Substrates in Instrumentation
- Used as precision substrates in instrumentation, where dimensional stability in thin section combined with wear resistance after heat treatment supports consistent instrument performance.
- ✦ Aerospace & Automotive Exhaust System Components
- Applied in aerospace, chemical processing, and automotive exhaust systems, where elevated-temperature capability and resistance to oxidation in low-sulfur, non-halide environments meet demanding service conditions.
- ✦ Phase Transformation & Heat Treatment Research
- Supports investigations into phase transformations, quench-and-temper heat treatment effects, and the balance between hardness and ductility in martensitic stainless alloys.
