Characteristics of 416 Stainless Steel
- Ultimate Machinability: Its sulfur-enhanced composition delivers superior free-cutting performance, enabling faster machining speeds, smoother finishes, and extended tool life, making it ideal for automatic screw machine applications.
- Hardenable for Strength: This martensitic grade can be heat-treated to achieve high strength and hardness, making it ideal for parts that require both durability and machinability.
- Cost-Effective for Mass Production: Due to its exceptional machinability, production costs for complex parts can be significantly reduced.
- Moderate Corrosion Resistance: In its hardened and polished condition, it offers fair resistance to corrosion from mild atmospheres, freshwater, and some neutral salts.
- Not Recommended for Welding: The high sulfur content causes hot cracking, making welding unsuitable for this material.
- Magnetic in All Conditions: Ferromagnetic in both annealed and hardened states, it attracts magnets with great strength.
- Ideal for Intricate Parts: It is the standard material for producing a wide variety of complex, high-precision machined components.
- Limited Formability: Ideal for machining, but not suitable for bending or cold forming, especially in non-annealed states.
