AISI 301 Stainless Steel Disk
Available Configurations
Properties common to all products in this list
Key Features
AISI 301 Stainless Steel Disk (UNS S30100) is a metastable austenitic stainless steel noted for its high tensile strength, adequate corrosion resistance, and pronounced strain-induced martensitic transformation response under mechanical deformation:
TRIP Effect Enhances Hardness & Wear Resistance
With 16-18% chromium and 6-8% nickel, the TRIP (transformation-induced plasticity) effect enhances hardness and wear resistance as the material deforms, providing a self-strengthening response under service loading.
Simultaneous Toughness & Work-Hardened Strength
AISI 301 Disk is well suited to applications where simultaneous toughness and work-hardened strength are required — a combination not readily available in stable austenitic or conventional martensitic alloy systems.
Adequate Corrosion Resistance
Adequate corrosion resistance supports reliable performance in transportation systems and mechanical assemblies exposed to moderately aggressive service environments.
High Tensile Strength Under Deformation
High tensile strength, amplified by the strain-induced transformation response under deformation, suits AISI 301 Disk to high-wear mechanical assemblies and spring-loaded interfaces subject to sustained mechanical loading.
Self-Reinforcing Wear Resistance
The TRIP effect's self-reinforcing wear resistance under deformation provides a performance advantage in resilient clamping disks and structural interfaces in vibration-prone systems where surface wear is a primary failure mode.
Industrial Applications
AISI 301 Stainless Steel Disk is used across transportation, mechanical assembly, and vibration-control sectors where the TRIP effect's self-strengthening response under deformation provides performance advantages:
- ✦ Resilient Clamping Disks
- Used as resilient clamping disks where high tensile strength combined with the TRIP effect's hardness enhancement under deformation provides reliable, self-reinforcing clamping performance under sustained mechanical load.
- ✦ Spring Washers
- Formed into spring washers, where the strain-induced martensitic transformation response delivers spring performance and wear resistance beyond that available from stable austenitic alloy systems.
- ✦ Structural Interfaces in Vibration-Prone Systems
- Used as structural interfaces in vibration-prone systems, where adequate corrosion resistance combined with the TRIP effect's self-reinforcing wear resistance under cyclic deformation supports long-term reliability.
- ✦ Transportation & High-Wear Mechanical Assemblies
- Applied in transportation systems and high-wear mechanical assemblies, where simultaneous toughness and work-hardened strength deliver performance where conventional stable austenitic disks would be insufficient.
- ✦ Fatigue & Crack Propagation Research
- Used to study fatigue resistance, crack propagation delay, and thermomechanical processing in metastable austenitic alloys, where the TRIP behavior of AISI 301 is of particular research interest.
