Fastcool 10®

FASTCOOL®-10 is a new grade of the high thermal conductivity steel family. It has been designed to be the most cost-effective solution in applications requiring exceptionally high thermal conductivities combined with good mechanical properties, with thicknesses available in excess of 1000 mm. FASTCOOL®-10 brings significant advantages to injection moulding due to its high thermal conductivity (double that of conventional steels), high polishability, high potential for cycle-time reduction, increased quality of the finished product through the elimination of haloes/weft and moulding marks. In addition, the use of advanced casting technology combined with the careful selection of high-quality plastics ensures a very low level of impurities, which, together with the very fine and homogenous microstructure, allows for excellent polishing, excellent photoetching and extreme homogeneity. The material was created specifically for application in mould heating and cooling technologies.

FASTCOOL®-10 is supplied in a pre-hardened state with an average hardness of 300 ± 30 HB and as it does not require any further hardening processes, it offers great opportunities for reducing production costs.

Polishability

Unique microstructure offers a high degree of polishability Levels of polishability comparable to special steels for plastic injection – mirror polishing better than MESH 3000 is possible

Welding

It must be remembered that high thermal conductivity and hardness must be maintained when welding:

The use of FASTCOOL® welding material is recommended If welding was carried out at cooling points, the entire workpiece must be hardened twice to restore the thermal properties of the welded part.

Machinability

FASTCOOL®-10 can be machined by conventional methods, using HSS tools or EDM technology. The machining parameters are comparable to those used for machining hot-rolled steels of similar hardness.
