Stainless Steel 410 is a type of stainless steel that is part of the martensitic steel. This category of stainless steel is characterized by its high hardness and strength, which comes from its high carbon content and the heat treatment processes it undergoes. Stainless Steel 410 contains a higher amount of chromium compared to other stainless steels, which provides it with good corrosion resistance.

• Chromium (Cr): 11.5% – 13.5%
• Carbon (C): Up to 0.15% – 0.20%
• Manganese (Mn): 1.0% max
• Silicon (Si): 1.0% max
• Nickel (Ni): 0.75% max
• Phosphorus (P): 0.04% max
• Sulfur (S): 0.03% max

• Tensile Strength: 480 – 700 MPa
• Yield Strength: 275 – 450 MPa
• Elongation: 15 – 20% (in 50 mm)
• Hardness: Can be hardened to 45 HRC (Rockwell Hardness Scale)

Stainless steel 410 has good corrosion resistance against atmospheric conditions and mild acids. It performs well in environments where it is exposed to air and water but can be prone to corrosion in more severe conditions.

SS 410 can be hardened by heat treatment to increase its hardness and strength. It can be heat treated at temperatures between 815°C to 900°C (1500°F to 1650°F), followed by quenching and tempering.

Stainless Steel 410 is magnetic due to its martensitic structure, which differentiates it from austenitic stainless steels like 304 or 316, which are typically non-magnetic.

Good machinability, especially in the hardened state. It can be readily machined and welded, though special techniques might be needed for welding due to its high carbon content.

• Cutlery: Knives and kitchen utensils.
• Industrial Equipment: Pumps, valves, shafts, and bearings.
• Automotive Parts: Exhaust systems and engine components.
• Tools and Hardware: Hand tools and fasteners.
• Aerospace: Aircraft parts.
• Marine: Marine hardware (in less severe conditions).
• Medical Instruments: Surgical tools.
• Consumer Products:: Fittings and fixtures.
• Industrial Processing: Heat exchangers.
• Military: Certain armament components.

• Corrosion Resistance: Provides good protection in mildly corrosive environments, normal atmospheric conditions, non-salt water, and most chemicals and solvents.
• High Strength and Hardness: Offers relatively high tensile strength and hardness compared to other stainless-steel grades.
• Wear Resistance: Due to its hardness, it excels in wear resistance, making it ideal for applications with high abrasion.
• Heat Resistance: Maintains mechanical properties at moderately elevated temperatures, providing reliable performance in heat-exposed applications.
• Machinability: While moderately machinable, good results can be achieved with appropriate tools and techniques.
• Cost-Effective: Lower alloy content makes it relatively inexpensive compared to most other stainless-steel grades.
• Heat Treatment Adaptability: Responds well to heat treatment, allowing for customization of mechanical properties to suit specific applications.

Stainless steel bright bars made from SS 410 material are known for their excellent mechanical properties and resistant to corrosion. These SS bright bars provide good hardness and moderate corrosion resistance.

These bright bars are produced by cold drawing or precision rolling of the steel, which provides a smooth, shiny finish, and tight dimensional tolerances. These SS 410 bright bars are often used in applications where precise dimensions and high surface quality are required.

Applications:

• Shafts, bolts, and screws
• Automotive components subjected to high stress and wear
• Industrial equipment parts requiring a combination of hardness and corrosion resistance
