TQ1
Characteristics
TQ 1 is an unalloyed Cr-Mo-V steel with very high toughness, firmness during the heat and resistance to the hot abrasion (higher than by other classic steels 1.2343, 1.2344, 1.2367). TQ 1 is produced only by ESU technology due to which the material has a high cleanness and a low content of trace elements. It is delivered in the soft-annealed state of max. 220 HB.
Suitability
TQ 1 is appropriate for using in the following applications during a very high stress: pressure casting, extrusion, stamping, hot working. It is very appropriate for highly polished parts of molds (e.g. production of headlights etc.) due to ESU properties.
