Hom 630 steel phaj yog hom 630 martensitic stainless hlau uas siv niobium. Hom 630 steel phaj yuav tsum tsis txhob siv ntawm qhov kub siab tshaj 300 degrees celsius thiab rau kev pabcuam cryogenic. Nws pom daim ntawv thov hauv cov rooj vag li qub thiab kev ua haujlwm ntawm cov khib nyiab nuclear. Hom 630 steel daim hlau raws li tau hais, ua rau lub zog siab tshaj plaws thaum tshav kub kho hauv 900 Fahrenheit. Nws yog magnetic thiab yooj yim welded rau fabrication. Nws txhawb kev laus kev kho mob Ie Conditions H900, H1025, thiab H1150D. Tus txheej txheem asme sa 693 hom 630 Kub Rolled Phaj muaj qhov ceev ntawm 7.75 g / cm3 thiab muaj peev xwm kub ntawm 460 J / kg Celsius.
