Mechanical properties:
– Higher tensile strength and hardness: The 416S21 steel grade has increased tensile strength and hardness due to its martensitic structure, which makes it more resistant to wear and abrasion.
– Improved toughness: The steel grade has improved toughness, making it more durable and less prone to cracking or fracturing under stress.
Technical properties:
– Enhanced machinability: The 416S21 steel grade has good machinability, allowing for easier and more efficient fabrication of components.
– Better heat treatment response: This steel grade responds well to heat treatment, which further improves its mechanical properties and corrosion resistance.
Chemical composition:
– Increased chromium and sulfur content: The 416S21 steel grade has a higher chromium content, which enhances its corrosion resistance. Additionally, the sulfur content improves machinability without sacrificing corrosion resistance.
– Controlled carbon content: The carbon content is carefully controlled to maintain a balance between hardness and toughness, contributing to the steel grade’s overall durability.
In summary, the 416S21 steel grade improves corrosion resistance and durability through its enhanced mechanical properties, improved technical properties, and carefully controlled chemical composition. These features make it a suitable choice for applications requiring resistance to corrosion and wear, such as in the manufacture of components for the automotive and aerospace industries, as well as in the production of tools and machinery.
