P460NH Matsayin Jirgin Karfe Plate

P460NH, wanda ake kira don samun ƙaramin ƙarfin amfanin gona na 460 MPa, babban ingancin jirgin ruwa ne na ƙarfe don amfani da tukunyar jirgi da ƙirƙira jirgin ruwa. Yana da wani al'ada lafiya hatsi karfe da kyau weldability halaye.

Sauran nau'ikan maki sun haɗa da…
NL1 - yana da kyau don amfani a cikin ƙananan yanayin zafi
NL2 - yana da kyau don amfani a cikin ƙananan yanayin zafi

Hakanan ana amfani da P460NH a aikace-aikacen iskar gas mai tsami inda karfe zai zama HIC Gwajin don auna abubuwan da ke haifar da fashewar hydrogen.
