In terms of mechanical properties, 416S21 has a higher machinability compared to other stainless steel grades. This is due to the addition of sulfur, which improves the steel’s machinability without compromising its other properties.
In terms of technical properties, 416S21 has good corrosion resistance and can be hardened by heat treatment. This makes it suitable for applications where corrosion resistance and high strength are required, such as in the manufacturing of valves, pump shafts, and gears.
In terms of chemical composition, 416S21 contains a relatively high amount of sulfur, which contributes to its improved machinability. It also contains chromium, which provides its corrosion resistance, and molybdenum, which enhances its resistance to pitting and crevice corrosion.
Overall, 416S21 steel distinguishes itself from other stainless steel grades with its improved machinability, good corrosion resistance, and ability to be hardened by heat treatment.
