These include:

  • general carbon steels
    (S235JR, S355J2, P265GH, C.22.8, 16Mo3, etc.)
  • heat-treatable steels, case-hardening steels
    (C.35, C.45, 16MNCR5, 42CrMoS4, etc.)
  • rust and acid resistant steels
    (1.4301, 1.4404, 1.4462, 1.4539, 1.4541, 1.4571, etc.)

    (aluminium, copper, copper nickel alloys, etc.)
  • Other special alloys

We only use materials that suit the application and function of your products.
