RUD stainless steel chains

RUD offers the right chain for a wide range of applications. For applications with high demands on rust and acid resistance, RUD stainless steel chains offer a high degree of

flexibility for manual and motor-driven hoists. All rust and acid-resistant chains are designed and produced according to DIN 5684 part 1 and part 2.

Special features of the RUD stainless steel chains:

  • resistant to rust and acid
  • from 4 mm to 16 mm chain diameter
  • similar to DIN 5684 part 1
  • grade P: RPA and grade S: RSA
  • without heat treatment
