ASTM A240 Type 410 Stainless Steel Sheet Plate
ASTM A240 Type 410 Stainless Steel Sheet & Plate | 410 / UNS S41000 - SHH STEEL
As a professional stainless steel supplier, SHH STEEL is pleased to present ASTM A240 Type 410 Stainless Steel Sheet and Plate. Also known as SS410 or UNS S41000, this grade is a basic martensitic stainless steel containing 11.5–13.5% chromium.
Type 410 is hardenable by heat treatment and can achieve high strength and hardness while providing moderate corrosion resistance in mildly corrosive environments. It is magnetic in both the annealed and hardened conditions. SHH STEEL supplies ASTM A240 Type 410 in both sheet and plate forms, covering thicknesses from 0.5 mm to 100 mm, with widths up to 2000–2500 mm and lengths up to 12000 mm. Custom sizes and surface finishes are available.
The material is typically delivered in the annealed condition with full Mill Test Certificates (EN 10204 3.1). Heat treatment (hardening and tempering) can be performed according to customer requirements. Whether for thin sheet fabrication or heavy plate applications, SHH STEEL provides consistent quality for engineering, valve, pump and general industrial projects worldwide.

Mechanical Properties
In the annealed condition, ASTM A240 Type 410 provides good formability. Higher strength and hardness can be achieved by hardening and tempering.
| Property | Value (Annealed) | Test Method |
|---|---|---|
| Tensile Strength | ≥ 450 – 515 MPa | ASTM A370 |
| Yield Strength (0.2% Offset) | ≥ 205 – 290 MPa | ASTM A370 |
| Elongation in 50 mm | ≥ 20% | ASTM A370 |
| Hardness | ≤ 217 HB / ≤ 96 HRB | ASTM E10/E18 |
| Density | 7.65 – 7.75 g/cm³ | — |
After hardening and tempering, hardness can typically reach 38–45 HRC depending on the heat treatment parameters.
Delivery Conditions
SHH STEEL supplies ASTM A240 Type 410 primarily in the annealed condition. Detailed capabilities by surface finish are as follows:
2B Finish (Cold-rolled, annealed, pickled and skin-passed)
- Typical thickness range: 0.5 mm – 6.0 mm
- Maximum width: up to 1500–2000 mm depending on thickness
- Preferred for applications requiring a smooth surface and good formability.
No.1 Finish (Hot-rolled, annealed and pickled)
- Typical thickness range: 3.0 mm – 100 mm
- Maximum width: up to 2000–2500 mm
- Standard finish for heavy plates used in engineering components and structural applications.
Other Finishes
- BA (Bright Annealed) and HL (Hairline) available on request in limited thickness ranges.
Protective PVC film can be applied on one or both sides. Precision cutting (plasma, laser or waterjet) and closer dimensional tolerances are available upon request. Hardening and tempering heat treatment can be arranged according to customer specifications.
Tolerances
Dimensional tolerances for ASTM A240 Type 410 sheet and plate follow ASTM A480/A480M.
- Thickness tolerances vary by product form and thickness.
- Width tolerance is typically +6 mm / 0 mm.
- Length tolerance for cut-to-length material is normally +10 mm / 0 mm.
- Flatness is controlled according to ASTM A480; improved flatness can be supplied for precision fabrication.
- Edge conditions include mill edge, slit edge, sheared edge or plasma/laser cut edge according to customer preference.
Tighter tolerances can be arranged for special projects.
Weldability
ASTM A240 Type 410 can be welded, but requires care due to its martensitic nature. Preheating (typically 150–250°C) and post-weld heat treatment (tempering) are often recommended to avoid cracking and restore ductility.
Matching or similar filler metals (e.g., ER410) or austenitic fillers (such as ER309L) may be used depending on the application. Controlled heat input and proper interpass temperature management are important. Welding procedures should be qualified according to the specific service requirements.
