Chemical Composition and Mechanical Properties of 410S Stainless Steel

410S (UNS S41008) is a low-carbon, non-hardening modification of 410 stainless steel with the following composition and properties:

Mechanical Properties:

Applications and Industries Using 410S Stainless Steel

410S is widely used in various industries due to its good oxidation resistance and moderate corrosion resistance:

1. Petroleum refining and petrochemical processing
2. Heat exchangers
3. Mining machinery
4. Thermal processing equipment
5. Gate valves and press plates
6. Food processing equipment

Manufacturing Process and Heat Treatment of 410S

The manufacturing process of 410S typically involves:

1. Melting raw materials in an electric arc or induction furnace
2. Continuous casting into slabs or billets
3. Hot rolling to reduce thickness
4. Cold rolling to achieve final dimensions
5. Annealing at 750-900°C for stress relief and improved ductility

410S primarily undergoes annealing as its main heat treatment process. It cannot be hardened through traditional heat treatment methods.

Corrosion and Oxidation Resistance of 410S

410S exhibits good oxidation resistance and moderate corrosion resistance:

• Can be used in continuous service up to 1300°F (705°C)
• Scaling becomes excessive above 1500°F (811°C) in intermittent service
• Offers good resistance to mild organic and mineral acids

Comparison of 410S with Other Stainless Steel Grades

410S offers improved weldability and formability compared to 410 due to its lower carbon content and non-hardening characteristics.

Formability and Welding Considerations for 410S Stainless Steel

Formability:

• Good formability through cold working methods
• Can be formed using bending, rolling, or stamping techniques

Welding:

• Excellent weldability by all standard methods
• No preheating or post-weld heat treatment typically required
• Cracking resistance when welded or exposed to elevated temperatures
