Characteristics of steel
Martensitic stainless steel resistant to corrosion. Steel displays the best corrosion resistance in hardened condition with a surface polished to give a mirror finisih. Properties: Magnetizable steelm good mechanical resistance and toughness, excellent for manufacturing of components that have to resist to aggressive plastics, good tool machinability thanks to its sulphur content, suitable for working in wet atmosphere and moisture, suitable for polishing, wear and corrosion proof, and very stable dimensionally during heat treatment.
Suitability of steel use
All kinds of cutting tools – dies and die-blocks in the plastics industry such as PVC, knives, shears, surgical instruments, moulds for plastics production, as well as for surgical instruments and measuring gauges.
