Nástrojová oceľ pre prácu za studena

Keďže požiadavky na nástroje rastú, výber správnej nástrojovej ocele na konkrétny účel sa stáva čoraz dôležitejší. Čo patrí medzi tieto požiadavky? Nástroj musí byť dostatočne odolný voči opotrebovaniu. Nástroj musí fungovať spoľahlivo a nesmie zlyhať kvôli predčasnému vyštiepeniu hrany, trhline alebo plastickej deformácii. Optimálnu hospodárnosť výroby nástrojov – najnižšie možné náklady na nástroj (vrátane údržby) prepočítané na vyrobený diel – je možné dosiahnuť len pri použití nástrojovej ocele vhodnej na konkrétny účel.
