Ferritic SS 410

Ferritic SS 410

Ferritic SS 410 is a type of stainless steel known for its unique blend of properties, offering a combination of corrosion resistance, high-temperature strength, and good hardenability. Unlike other stainless steels, Ferritic SS 410 contains a relatively low carbon content, making it highly resistant to oxidation and scaling in high-temperature environments. The material also exhibits a body-centered tetragonal (BCT) crystal structure, which is characteristic of martensitic stainless steels. Stainless steel 410 has superior hardenability due to the presence of elements like nickel, cobalt, and copper. These elements help stabilize the austenitic phase, making it easier for the material to undergo martensitic transformation. As a result, Ferritic SS 410 is widely used in applications where both strength and corrosion resistance are required, such as in the automotive, aerospace, and chemical industries. Despite its many advantages, stainless steel 410 is not as corrosion-resistant as austenitic stainless steels, so it is best suited for environments with moderate corrosion exposure. Overall, Ferritic SS 410 is a versatile material offering a balanced performance in various industrial applications.

Is SS 410 magnetic?

Yes, SS 410 is magnetic in both the annealed and hardened conditions.

Physical properties of stainless steel 410

Grade Density (g/cm3) Elastic Modulus (GPa) Mean Co-eff of Thermal Expansion (μm/m/°C) Thermal Conductivity (W/m.K) Specific Heat ( J/Kg.K) Electrical Resistivity (μΩ.m)
SS 410 7.8 200 0-100°C 0-315°C 0-538°C at 100°C at 500°C 0-100°C 570

At temperatures ranging from 815 °C to 900 °C, Ferritic SS 410 can be completely annealed, but slow furnace cooling followed by air-cooling is essential to achieve optimal properties. For process annealing of stainless steel 410, temperatures between 650 °C and 760 °C are typically used, again followed by air-cooling.

Ferritic SS 410 exhibits good scaling resistance at temperatures up to a maximum of 650 °C, making it suitable for high-temperature applications. However, the mechanical properties of SS 410 may degrade when exposed to temperatures between 400 °C and 580 °C, leading to reduced strength and hardness.

To enhance the mechanical characteristics and hardness of stainless steel 410, it can undergo hardening at temperatures between 925 °C and 1010 °C, with air or oil quenching as the preferred methods. After hardening, tempering is recommended to further improve the material's toughness and hardness. However, it is not advisable to perform tempering at temperatures ranging from 400 °C to 580 °C, as this can negatively affect the material’s properties.

Ferritic SS 410 is widely used in a variety of industries, including automotive, aerospace, and manufacturing, due to its excellent strength and moderate corrosion resistance. When carefully heat-treated, Ferritic SS 410 offers an optimal balance of toughness, wear resistance, and structural integrity for demanding applications.

Ferritic SS 410 can be welded using all conventional welding techniques, including fusion and resistance methods. However, preheating the material to temperatures between 150 °C and 260 °C is essential before welding to reduce the risk of cracking. After welding, annealing treatment is recommended to relieve stresses and ensure optimal mechanical properties. Ferritic SS 410 is known for its good weldability, making it a popular choice for a variety of industrial applications that require strong, durable joints.

The unique properties of SS 410 are primarily due to its composition, which includes 11.5% to 13.5% chromium and 0.12% carbon. This composition enhances its mechanical strength and corrosion resistance, offering a low-cost alternative for industries where these properties are critical. Ferritic SS 410 is widely used in applications such as oil and natural gas extraction, turbine blades, compressors, and various mechanical components like rods, valves, shafts, and bearings.
