# Oceli pro protlačování za studena

Oceli pro protlačování za studena jsou konstrukční materiály určené k výrobě součástí tvářením za studena a protlačováním. Kombinují tažnost potřebnou pro značnou plastickou deformaci s pevností a houževnatostí vyžadovanou u spojovacích součástí tvářených za studena, automobilových dílů a dalších přesných součástí.
