Cov khoom siv lub cev ntawm cov hlau sib xyaw ua ke yog dab tsi?

Alloy hlau puag ncig baryog ib yam khoom siv tau ntau yam thiab ruaj khov uas siv dav hauv ntau yam lag luam vim nws cov khoom zoo heev. Muaj ntau hom hlau puag ncig uas paub txog lawv lub zog, kev ruaj khov thiab kev tiv taus kev hnav, ua rau lawv zoo tagnrho rau ntau yam kev siv.
Ib qho ntawm cov khoom tseem ceeb ntawm cov hlau alloy carbon bar yog nws lub zog tensile siab. Qhov no txhais tau tias nws tuaj yeem tiv taus lub zog lossis kev ntxhov siab tsis tawg lossis deforming. Qhov no ua rau nws yog qhov kev xaiv zoo heev rau cov ntawv thov uas lub zog thiab kev ua haujlwm ntev yog qhov tseem ceeb, xws li kev tsim kho vaj tse, choj thiab lwm yam qauv.
Lwm yam khoom tseem ceeb ntawm cov hlaucarbon steel puag ncig pas nrig / baryog nws qhov kev siv tshuab zoo heev. Qhov no txhais tau tias nws tuaj yeem yooj yim ua kom zoo li daim duab, txiav thiab tsim ua ntau yam duab thiab qhov ntau thiab tsawg yam tsis poob nws lub zog lossis kev ncaj ncees. Qhov no ua rau nws yog qhov kev xaiv nrov rau kev tsim cov khoom thiab cov khoom uas xav tau qhov ntev meej thiab kev kam rau siab.
Ntxiv mus, alloy en8 steel round bar muaj qhov weldability zoo, uas tso cai rau nws kom yooj yim welded rau lwm yam khoom siv yam tsis cuam tshuam rau nws lub zog lossis kev ua haujlwm ntawm cov qauv. Qhov no ua rau nws yog qhov kev xaiv ntau yam rau kev tsim cov qauv thiab cov khoom uas xav tau kev vuam, xws li hauv kev tsim kho thiab kev lag luam tsheb.

Tsis tas li ntawd xwb, cov hlau alloy puag ncig muaj kev tiv thaiv xeb zoo heev, ua rau nws tsim nyog siv rau hauv qhov chaw nyuaj nrog cov dej noo, tshuaj lom neeg lossis qhov kub thiab txias heev. Cov yam ntxwv no ua kom cov khoom siv ruaj khov thiab txhim khu kev qha dhau sijhawm, txawm tias nyob hauv cov xwm txheej nyuaj.
Zuag qhia tag nrho, cov khoom siv lub cev ntawmalloy puag ncig cam khwb cia hlau tuav, suav nrog lub zog tensile siab, ua haujlwm tau zoo, weldability thiab corrosion tsis kam, ua rau nws yog thawj qhov kev xaiv rau ntau yam kev siv hauv kev lag luam. Txawm siv rau hauv kev tsim kho, kev tsim khoom lossis kev tsim kho, alloy steel round bar muab lub zog thiab kev ntseeg siab uas xav tau los ua tiav txoj haujlwm.
