GTCS®-450 / GTCS®-470

GTCS® steel grades feature very low thermal conductivity at comparable levels of ceramic isolation materials, combined with the mechanical properties of steels. GTCS® are typically used in hot forming applications in order to reduce cooling in certain tool areas through reduced heat extraction by GTCS®, or to produce tool segments with graduated properties.

Delivery Condition:

  • Annealed or pre-hardened - for detailed information please contact ROVALMA

Typical Working Hardness:

  • The working hardness range after application of the proper heat treatment for GTCS®-450 is typically 38-40 HRc achieving higher toughness levels than GTCS®-470, which can be hardened up to 50 HRc.
