Cromax 280X hårdkrommet stempelstang

Sylindermateriale 
  • Cromax 280X is based on a low carbon, microalloyed steel combining high strength with excellent machinability and weldability
  • For 90 mm, yield and tensile strength are 20% higher than is normal for hard-chrome bars based on low-carbon weldable steel
  • In comparison with standard products based on grade 20MnV6, the superior properties profile of Cromax 280X offers a number of potential advantages in the design and manufacture of fluid-power cylinders, not the least of which is the possibility to downsize piston rods without loss of load-bearing capacity, thereby reducing not only weight but also cost
