Steel rau qhov twg sulfur tau ntxiv rau hauv cov nyiaj tswj tom qab ua kom zoo. Cov sulfur yog ntxiv los txhim kho machinability.
Resulfurized steel txhais li cas?
Resulfurized steel tuav muaj tshuaj pleev ib ce ntawm Carbon, Maganese, Phosphorus, thiab Sulfur. Sulfur yog cov khoom ntxiv rau carbon steel. Thaum tshuaj xyuas AISI / SAE steel qib, qib ntawm cov hlau yog cov hlau resulfurized yog tias thawj ob tus lej yog 11.
Rephosphorized steel yog dab tsi?
Phosphorus hauv cov hlau tuaj yeem muaj txiaj ntsig zoo thiab muaj kev phom sij. … Vim yog cov khoom no, cov hlau rephosphorized high-strength yog dav siv rau cold-forming applicationsPhosphorus kuj tseem siv los ua ib qho ntxiv hauv cov hlau los txhim kho cov yam ntxwv ntawm kev ua haujlwm thiab atmospheric corrosion resistance.
Dab tsi yog Resulfurized carbon steel?
Cov tsis-resulfurized high-manganese carbon steels yog tsim los kom ntseeg tau tias kev ua haujlwm zoo dua. … SAE 1018 qhia tias tsis hloov cov pa roj carbon steel uas muaj 0.18% carbon. SAE 5130 qhia tias chromium alloy hlau muaj 1% ntawm chromium thiab 0.30% carbon.
Dab tsi yog cov hlau ua tau zoo tshaj plaws?
Qib 316 steel muaj qhov ntsuas qhov ua tau zoo ntawm 60, thaum 316B muaj qhov ntsuas qhov ua tau zoo ntawm 50. Qib 304 thiab 304L muaj qhov kev ntsuas tib yam ntawm 70 los ntawm American Iron thiab Steel Institute lossis AISI cov qauv. Rau kev sib piv, alloy 303 yog qhov yooj yim tshaj plaws machined stainless hlau.

Pre tin plated steel yog dab tsi?
Tinplate muaj cov nplooj ntawv hlau, coated nrog ib txheej nyias ntawm tin. Ua ntej qhov tshwm sim ntawm pheej yig milled steel lub nraub qaum hlau yog hlau. Thaum ib zaug siv dav dua, qhov tseem ceeb ntawm kev siv tinplate tam sim no yog kev tsim cov kaus poom .
Dab tsi yog steel tawv?
Lub sij hawm hardened steel feem ntau yog siv rau nruab nrab lossis siab carbon steel uas tau muab kev kho cua sov thiab ces quenching ua raws li tempering. Lub quenching tshwm sim nyob rau hauv lub tsim ntawm metastable martensite, cov feem ntawm uas yog txo mus rau qhov xav tau npaum li cas thaum tempering.
Annealed steel yog dab tsi?
Annealing steel lossis lwm yam hlau suav nrog cua sov rau qhov kub thiab txias ntawm tus nqi teev. Ua li no tshem tawm impurities hauv cov nplej, ua rau cov hlau ductility thiab txo nws cov hardness . annealed steel siv rau dab tsi? Annealing yog txheej txheem kev kho cua sov uas hloov cov microstructure ntawm cov khoom los hloov nws cov khoom siv hluav taws xob lossis hluav taws xob.
Av nplaum tempered steel yog dab tsi?
Av nplaum tempering yog daim duab kos duab nrog rau kev tshawb fawb. … Lub hauv paus ntsiab lus tom qab av nplaum tempering yog ua tiav ob qho tib si hardness thiab yooj, uas sib npaug zog. Ib qho nyuaj txiav ntug, thiab ib tug saj zawg zog qaum.
Cov kua compressed steel yog dab tsi?
Cov kua dej yog tsim los ntawm tus kws tshaj lij Askiv zoo, Sir Joseph Whitworth. Nws siv nws rau nws rab phom (uas suav nrog cov phom loj) thaum xyoo 1880s. Nws tau raug hu ua "kua" vim nws tau compressed rau hauv cov duab thaum nyob rau hauv ib qho kub heev, malleable lub xeev… Thaum pib nws tej zaum tsis muaj zog dua Damascus steel .
