Soğuk ekstrüzyon çelikleri
Soğuk ekstrüzyon çelikleri, soğuk şekillendirme ve ekstrüzyon yoluyla bileşenlere dönüştürülmek üzere tasarlanmış mühendislik malzemeleridir. Önemli plastik deformasyon için gerekli sünekliği, soğuk şekillendirilmiş bağlantı elemanları, otomotiv parçaları ve diğer hassas bileşenler için gereken mukavemet ve toklukla birleştirirler.
