Stainless Steel Grades

Stainless steels like SUS304, 304L, 316, and their variants are renowned for their high resistance to corrosion, making them ideal for environments exposed to moisture, chemicals, or varying temperatures. 304 and 304L stainless steels are commonly used in general applications, while 316 and 316L, with added molybdenum, offer enhanced resistance to chlorides and acids, suitable for marine and chemical environments.

Maintenance Tips

Regularly clean stainless steel components to avoid surface contamination that can lead to rust. A simple wipe-down with a mild detergent and water is often sufficient, followed by a rinse and drying. Avoid contact with chlorides or harsh chemicals that can cause pitting or staining, especially in grades like 316.

Industry Applications
  • Medical and Pharmaceutical: Used in surgical instruments, implants, and sanitary tubing
  • Food Processing: 304 and 316 stainless steels for food-grade equipment
  • Chemical Processing: 316L and 316Ti for harsh chemical environments
  • Marine: 316 and 316L for saltwater corrosion resistance
  • Automotive and Aerospace: 410 and 420 grades for high-strength applications
