GSF
Characteristics
Nickel-chrome–molybdenum-vanadium steel GSF from the production of German steelworks KIND&Co heat-treated to the value of 1.350 Mpa. The steel has higher toughness and higher hardness during the heat than the classic steel W. Nr. 1.2714 while the resistance to the hot abrasion remained the same. Due to the already carried out heat treatment the production cycle of die can be shortened and the higher effectiveness of production can be reached.
Suitability
The steel GSF is appropriate for the production of forge tools, especially the dies under forging drop hammers.
