Txheej txheem cej luam ntawm Cov Yeeb Nkab Hlau
Nws tau muaj ntau tshaj li 70 xyoo txij li kev tsim cov yeeb nkab hlau yeeb nkab hauv xyoo 1940. Nrog nws lub zog siab, siab elongation, corrosion tsis kam, tsis kam ua rau poob siab, kev tsim kho yooj yim thiab ntau lwm yam zoo, cov yeeb nkab hlau yog qhov kev xaiv zoo tshaj plaws hauv lub ntiaj teb niaj hnub no rau kev xa dej thiab roj kom nyab xeeb. Ductile hlau, tseem hu ua nodular hlau los yog spheroidal graphite hlau, yog tus cwj pwm los ntawm lub xub ntiag ntawm spheroidal graphite nyob rau hauv lub resulting castings.

Cov yam ntxwv ntawm cov kav hlau kav hlau
Cov kav dej kav dej muaj nyob rau hauv ntau txoj kab uas hla ntawm 80 hli mus rau 2000 hli thiab tsim nyog rau ob qho tib si kev xa dej thiab kev xa tawm (raws li BS EN 545) thiab cov kav dej phwj tuaj (raws li BS EN 598). Cov kav hlau kav dej yog qhov yooj yim rau kev sib koom ua ke, tuaj yeem muab tso rau hauv txhua qhov huab cua thiab feem ntau tsis tas yuav xaiv cov khoom siv rov qab. Nws qhov kev nyab xeeb siab thiab muaj peev xwm ua kom haum rau hauv av txav ua rau nws yog cov khoom siv zoo tshaj plaws rau kev siv ntau yam.

Daim ntawv thov Iron
Ductile hlau muaj zog thiab ductility ntau dua li cov hlau grey. Cov khoom no tso cai rau nws siv tau zoo hauv ntau hom kev lag luam, nrog rau cov yeeb nkab, cov khoom siv tsheb, lub log, lub thawv iav, lub twj tso kua mis, lub tshuab thav duab rau kev lag luam cua, thiab ntau ntxiv. Vim tias nws tsis tawg zoo li cov hlau grey, cov hlau nplaum kuj muaj kev nyab xeeb siv rau hauv kev tiv thaiv kev tiv thaiv, xws li bollards.
