  • Widely used in shafts, pumps, valve parts, and fasteners due to its wear resistance.
Faqs:
  • What are the main applications of 9Cr18 / 95Cr18 / 440C stainless steel round bars?
    These round bars are ideal for high-strength, wear-resistant components such as shafts, pumps, valve parts, fasteners, and springs due to their excellent corrosion resistance and durability.
  • What are the heat treatment specifications for 9Cr18 stainless steel?
    The heat treatment includes annealing at 800-920°C (slow cooling), quenching at 1000-1050°C (oil cooling), and tempering at 200-300°C (oil or air cooling) to achieve optimal hardness and performance.
  • How does 9Cr18 stainless steel compare to other grades like 440C?
    9Cr18 (95Cr18) is equivalent to 440C and offers similar properties, including high carbon and chromium content, making it suitable for high-strength, corrosion-resistant applications. It is also comparable to DIN 1.4125 and JIS SUS 440C.
