Hasco’s plate program, especially in the P1 range, has now been supplemented by a pre-hardened steel, 1.2714HH. This pre-hardened EU tool steel is designed for dimensional stability and toughness. Hasco says that with a maximum hardness of 400 HB, it makes for optimum processing properties in machinability.

Benefits to users include excellent material properties for machining, welding, surface coating and use in injection molding tools, the company says. Other applications for the material include the efficient production of cavity inserts, cores and sliders. The steel is also designed for wear resistance and polishing and etching properties. It can be nitrided, coated at temperatures below 510°C and has good thermal conductivity. Performance is enhanced by the high-precision machining and surface quality as well as the plane-parallelism. The tolerances are geared to modern manufacturing techniques. Plates made from this steel are readily available from stock in the usual measurements. Special dimensions as well as P and K20 plates of 1.2714HH are available on request.
