Isıya dayanıklı döküm çelikleri

Isıya dayanıklı döküm çelikleri, yumuşama ve ısıl bozunmaya direncin önemli olduğu yüksek sıcaklıklardaki kullanım için formüle edilmiş demir esaslı döküm alaşımlarıdır. Döküm şekillerinin ve ısıtma sırasında güvenilir mekanik performansın gerekli olduğu fırın bileşenlerinde, ısıl işlem ekipmanlarında ve diğer yüksek sıcaklık tesis parçalarında kullanılırlar.
