Mechanical Properties:
– High tensile strength and hardness: 416S21 steel grade has a tensile strength of 700-850 MPa and a hardness of 160-270 HB, making it suitable for high-stress environments where strength and hardness are crucial.
Technical Properties:
– Good machinability: This steel grade has excellent machinability, making it easy to work with during fabrication and manufacturing processes in high-stress environments.
– Resistance to corrosion and oxidation: 416S21 steel grade has good resistance to corrosion and oxidation, which is essential for maintaining structural integrity in harsh environments.
Chemical Composition:
– High levels of chromium and carbon: The high chromium content (12-14%) in 416S21 steel provides it with excellent corrosion resistance, while the carbon content (0.15% max) contributes to its high strength and hardness.
– Addition of sulfur: The sulfur content in 416S21 steel grade improves its machinability, making it easier to machine and fabricate for high-stress applications.
Overall, the combination of these mechanical, technical, and chemical properties makes 416S21 steel grade the ultimate choice for high-stress environments, where strength, hardness, machinability, and corrosion resistance are essential.
