Lub cev muaj zog ntawm 1.4028
Qhov ceev yog 7.76 kg / dm³ thiab melting point yog 1365 degree. Ntawm qhov sib txawv ntawm qhov kub thiab txias, nws lub cev muaj zog xws li thermal conductivity thiab lub peev xwm kub tshwj xeeb kuj txawv. Hais txog cov khoom siv kho tshuab, 1.4028 muaj qhov sib txawv tensile lub zog thiab elongation nyob rau hauv ntau lub xeev xa khoom.

Tsis tas li ntawd, cov txheej txheem kev kho cua sov ntawm 1.4028 suav nrog cua sov rau 800 ~ 900 degree thiab tom qab ntawd cua txias lossis txias txias kom tau txais qhov xav tau hardness thiab mechanical zog. 1.4028 yog dav siv nyob rau hauv kev tsim khoom ntawm high-strength qhov chaw, hnav qhov chaw uas dais high-siv siab loads thiab ua hauj lwm nyob rau hauv corrosive xov xwm tej yam kev mob, xws li cov cuab yeej thiab springs ua hauj lwm hauv qab no 300 degree, shafts, bolts, li qub, bearings, thiab lwm yam. hauv qab 400 degree.
