ASME SA240 410 Stainless Steel Plate | SA240 Type 410

As a professional stainless steel plate supplier and China Mill-Direct Supply / Mill Direct Exporter, SHH STEEL is pleased to present ASME SA240 410 Stainless Steel Plate, also known as SA240 Type 410.

ASME SA240 Type 410 is a basic martensitic stainless steel containing approximately 11.5–13.5% chromium. Unlike the austenitic 300-series grades, Type 410 can be hardened and tempered by heat treatment to achieve a wide range of mechanical properties, from relatively soft and ductile to high strength and hardness. In the annealed condition it offers moderate corrosion resistance — significantly better than carbon steel or low-alloy steels, but lower than austenitic grades such as 304 or 316.

Type 410 is magnetic in all conditions and is widely used for applications requiring a combination of strength, hardness, wear resistance and moderate corrosion resistance, such as cutlery, valve components, pump parts, shafts, turbine blades, fasteners and petrochemical equipment.

SHH STEEL supplies ASME SA240 410 as true Mill Direct Supply, sourcing directly from major Chinese stainless steel mills. This model delivers competitive mill pricing, consistent quality, full heat traceability and shorter lead times. We offer a practical dimensional range and can supply material in the annealed condition or with specific heat-treatment conditions according to customer requirements.

Heat Analysis (Ladle Analysis) according to ASME SA240 Type 410:

Product Analysis (typical permissible variations):

The 12% chromium content provides the basic stainless character and moderate corrosion resistance, while the carbon level allows the steel to be hardened by quenching and tempering.

Annealed Condition (typical)

Hardened & Tempered Condition Type 410 can be heat treated to achieve a wide range of strength and hardness levels. Typical tempered properties can reach tensile strengths of 700–1000 MPa or higher depending on the tempering temperature, with corresponding increases in hardness and reductions in ductility.

Physical Properties

• Density: approximately 7.70–7.75 g/cm³
• Magnetic: Magnetic in all conditions
• Melting Range: approximately 1480–1530°C

ASME SA240 410 is selected when heat-treatable strength and moderate corrosion resistance are required. For improved weldability with similar corrosion performance, astm a240 type 410s stainless steel sheet plate is often preferred. For higher hardness, Type 420 is considered. When superior corrosion resistance is needed, austenitic grades such as astm a240 type 304 stainless steel sheet plate or astm a240 type 316l stainless steel sheet plate should be used.

ASME SA240 Type 410 offers moderate corrosion resistance in atmospheric, fresh-water and mild chemical environments. It performs better than carbon steels and many low-alloy steels, but is significantly less resistant than austenitic grades (304/316) in chloride or strongly corrosive media.

In the hardened and tempered condition, corrosion resistance is generally lower than in the fully annealed condition. The grade is not recommended for continuous exposure to seawater or strongly acidic chloride environments.

ASME SA240 Type 410 has limited weldability compared with austenitic stainless steels. Preheating (typically 200–300°C) and post-weld heat treatment (tempering or annealing) are usually required to avoid cracking and to restore toughness and corrosion resistance.

Matching or slightly higher-alloy filler metals (E410 / ER410) are commonly used. Welding of thick sections requires careful procedure control. For applications involving significant welding, the lower-carbon Type 410S is often preferred.

Heat treatment is a key advantage of Type 410 and allows a wide range of mechanical properties.

Annealing

• Temperature: 815 – 900°C
• Cooling: Furnace cool or air cool

Hardening

• Austenitizing temperature: 925 – 1010°C
• Quenching: Oil or air (depending on section size)

Tempering

• Temperature range: 200 – 700°C (selected according to required strength/hardness/toughness balance)
• Holding time: typically 1–2 hours per 25 mm of thickness, followed by air cooling

Proper control of hardening and tempering cycles is essential to achieve the desired combination of strength, hardness and toughness.

SHH STEEL regularly supplies ASME SA240 410 in No.1 and 2B finishes, and can provide other finishes according to project requirements.

Dimensional tolerances for ASME SA240 410 Stainless Steel Plate conform to ASME SA240 and the general requirements of ASTM A480.
