Steel muaj zog dua hlau (yield thiab qhov kawg tensile zog) thiab tawv dua ntau hom hlau ib yam nkaus (feem ntau ntsuas raws li tawg toughness). Cov hom hlau feem ntau muaj qhov sib ntxiv ntawm tsawg dua. 5% carbon los ntawm qhov hnyav. … Lwm cov ntsiab lus uas feem ntau pom hauv cov hlau yog manganese, silicon, phosphorus, thiab sulfur.

Dab tsi yog hlau muaj zog tshaj?

Tungsten muaj lub zog tensile siab tshaj plaws ntawm cov hlau ntshiab - txog li 500,000 psi ntawm chav tsev kub. Txawm tias qhov kub siab tshaj 1,500 ° C, nws muaj lub zog tensile siab tshaj plaws. Txawm li cas los xij, tungsten hlau yog nkig, ua rau nws siv tsawg dua hauv nws lub xeev ntshiab.

Puas yog hlau ruaj dua hlau?

Feem ntau, vim nws cov khoom muaj zog ntxiv, steel yog siv ntau dua li hlau hauv kev lag luam loj xws li kev tsim kho. Nws yog ntau ruaj thiab yuav tsis xeb li yooj yim, thiab kuj muaj zog dua thiab compression zog.

Yuav muaj zog npaum li cas piv rau steel?

Thaum muaj tsis muaj qhov sib txawv loj thaum nws los txog lub zog tensile, cov hlau nplaum muaj lub zog ntau dua (40 ksi). Cam khwb cia hlau, ntawm qhov tod tes, tsuas tuaj yeem ncav cuag 36 ksi yield zog. Raws li lub zog ntawm ductile hlau nce ductility txo. Ductile hlau muaj superior shock absorption rau steel.

Puas yog hlau yog hlau uas muaj zog tshaj?

Iron - Ib qho ntawm cov khoom siv hlau, thiab mus rau hlau rau cov cuab yeej thiab riam phom tsim thoob plaws lub hnub nyoog, hlau ua tiav cov npe ntawm cov hlau uas muaj zog tshaj plaws hauv ntiaj teb cam khwb cia hlau Cov qhab nia kwv yees li 5 ntawm Mohs nplai, thiab nws cov txiaj ntsig thiab lub zog tensile yog li 246 thiab 414 Mpa feem.
