- Coefficient of thermal expansion: ~10.0×10⁻⁶/°C (20–100°C)
Standards
431 stainless steel is specified under the following standards:
- ASTM A240/A240M: Covers plates, sheets, and strips, designated as 431.
- UNS: Unified Numbering System designation is S43100.
- EN 10088-2: European standard, classified as X5CrNi17-2 (material number: 1.4057).
Equivalent Grades
- USA: UNS S43100, ASTM 431
- Europe: EN 1.4057 (X5CrNi17-2)
- Japan: JIS SUS431
- China: GB 1Cr17Ni2
Applications
431 stainless steel is valued for its balance of strength and corrosion resistance, making it suitable for:
- Automotive industry: Components like valve stems, exhaust systems, and high-strength fasteners.
- Aerospace: Parts requiring high tensile strength and resistance to atmospheric corrosion, such as aircraft fittings.
- Oil and gas: Valves, pumps, and shafts for medium-corrosion environments.
- Medical equipment: Surgical instruments and orthopedic implants (due to biocompatibility and strength).
- General engineering: Gear shafts, bolts, and high-strength structural parts in mildly corrosive conditions.
Laser Cutting of 431 Stainless Steel Plate
Laser cutting is a highly effective method for processing 431 stainless steel, offering distinct advantages for both thin and medium-thickness plates.
-
Processing Range:
- Suitable for plate thicknesses typically up to 20mm, depending on laser power (e.g., 3–6 kW fiber lasers handle 1–15mm efficiently; higher-power lasers can cut thicker materials).
- Capable of cutting complex shapes, precision holes, slots, and custom profiles with minimal setup changes.
-
Key Advantages:
- High Precision: Narrow kerf width (0.1–0.3mm) and tight tolerances (±0.05mm), ideal for intricate designs.
- Minimal Heat-Affected Zone (HAZ): Reduces material distortion and preserves the mechanical properties (e.g., strength, corrosion resistance) of 431, unlike plasma or oxy-fuel cutting.
- Clean Edges: Produces burr-free, smooth edges, eliminating the need for post-processing (e.g., grinding).
- Efficiency: Faster cutting speeds for thin to medium plates compared to mechanical methods (e.g., sawing), with no tool wear.
- Versatility: Adaptable to various plate sizes and geometries, supporting both small-batch prototyping and large-scale production.
