SUPERPLAST 300 ®

Characteristics

The steel is developed for the purpose of more qualitative classical qualities of steels – W.Nr. 1.2378, 12311 and 1.2312. Due to the highly clear structure it reaches excellent workability (of about 15% better than by 1.2738), polishability, corrodibility and it increases the quality of surface and mechanical properties of produced injection and pressing parts. Higher heat conductivity SP300® (P) increases the productivity of the tool. Easy weldability and easier repairs and alterations of the mold design.

Suitability

Heat-treated steel to the firmness from 290 to 320 HB is used for big molds for plastics injection and big frames of molds.

Tool steel meets the requirements of various kinds of tools, e.g. for machining, hot- and cold-working, measuring instruments and die-casting moulds. We also offer high-speed steel.

Tool steel meets the requirements of various kinds of tools, e.g. for machining, hot- and cold-working, measuring instruments and die-casting moulds. These tool materials conform to great quality demands of steel, like temper, strength, toughness, resistance to tempering, hardening capacity, dimensional stability, etc. The range of tool steel in our store includes products from renowned manufacturers. We also supply high - speed steel.

Special tool steel is suitable for the manufacture of moulds, dies and pressing tools. This steel has better end-use properties than common classic steel, therefore it can help saving considerable amounts of money in manufacture.

This patented Swedish steel is distinguished by its high range of use. It is suitable for the manufacture of tools and moulds as well as machinery parts. This material can replace many kinds of classic tool and structural steel.

We supply these grades of steel: St52.3, C45, 16MnCr5, 42CrMo4
