Company Profile


	Hot-work tool steels
	Cost-effectiveness and productivity are the essence of production. Short service lives or long downtimes come dear to the company. Consequently, it is advisable to use high-quality hot work tool steels for the tools for chip less forming of work pieces made of ferrous and non-ferrous metals and their alloys – for die-casting, extrusion, drop forging, and also for tube and glass manufacturing. No matter whether the heated material is to be shaped by high pressure or cast in a given shape S.K.International supplies hot work tool steel for long service lives.
