Cov pa roj carbon steel, tseem hu ua carbon steel, hais txog hlau thiab carbon alloys uas muaj tsawg dua 2% carbon, carbon steel ntxiv rau carbon feem ntau muaj ib tug me me ntawm silicon, manganese, sulfur thiab phosphorus.
Stainless hlau, tseem hu ua stainless acid-resistant steel, hais txog qhov tsis kam ntawm huab cua, chav, dej thiab lwm yam tsis muaj zog corrosive media thiab acids, alkalis, ntsev thiab lwm yam tshuaj impregnating media corrosion steel. Hauv kev xyaum, cov hlau uas tsis muaj zog corrosive media feem ntau hu ua stainless hlau, thiab cov hlau uas tiv taus tshuaj lom neeg corrosion yog hu ua acid-resistant steel.
(1) Corrosion thiab abrasion tsis kam
Stainless hlau yog ib qho hlau uas tiv taus corrosion los ntawm cov xov xwm tsis muaj zog xws li huab cua, chav, dej thiab tshuaj lom neeg tawm tsam xws li acids, alkalis thiab ntsev. Thiab qhov kev ua haujlwm no feem ntau yog vim qhov sib ntxiv ntawm cov khoom tsis muaj hlau - chromium. Thaum cov ntsiab lus chromium ntau dua 12%, qhov saum npoo ntawm stainless hlau yuav tsim ib txheej ntawm oxidized zaj duab xis, feem ntau hu ua passivation zaj duab xis, nrog rau txheej ntawm oxidized zaj duab xis no yuav tsis yooj yim rau yaj nyob rau hauv tej yam xov xwm, plays ib tug zoo cais lub luag hauj lwm, muaj zog corrosion kuj.
Carbon steel hais txog cov hlau-carbon alloy uas muaj tsawg dua 2.11% carbon, tseem hu ua carbon steel, nws hardness ntau dua stainless hlau, tab sis qhov hnyav yog ntau dua, plasticity qis dua, yooj yim rau xeb.
(2) sib txawv compositions
Stainless hlau yog luv rau stainless acid-resistant steel, resistant rau huab cua, chav, dej thiab lwm yam tsis muaj zog corrosive media los yog nrog stainless hlau yog hu ua stainless hlau; thiab yuav tiv taus cov tshuaj corrosive media (acids, alkalis, ntsev thiab lwm yam tshuaj impregnation) corrosion ntawm cov hlau yog hu ua acid-resistant steel.
Cov pa roj carbon steel yog cov hlau-carbon alloy nrog cov ntsiab lus carbon ntawm 0.0218% txog 2.11%. Kuj hu ua carbon steel. Nws kuj feem ntau muaj me me ntawm silicon, manganese, sulfur, thiab phosphorus.
(3) Nqi
Lwm qhov kev txiav txim siab tseem ceeb yog tus nqi sib txawv ntawm carbon steel thiab stainless hlau. Txawm hais tias cov hlau sib txawv muaj cov nqi sib txawv, cov hlau tsis muaj steel feem ntau kim dua cov hlau, feem ntau yog vim qhov sib ntxiv ntawm ntau yam alloying ntsiab, xws li chromium, nickel, thiab manganese, rau stainless hlau.
Piv nrog rau carbon steel, stainless hlau muaj ntau ntawm lwm yam alloys sib xyaw thiab yog kim dua piv rau carbon steel. Ntawm qhov tod tes, carbon steel feem ntau muaj cov khoom pheej yig ntawm cov hlau thiab carbon. Yog tias koj nyob ntawm pob nyiaj nruj rau koj qhov project, ces carbon steel yuav yog qhov kev xaiv zoo tshaj plaws.
Qhov twg yog qhov nyuaj, steel lossis carbon steel?
Cov pa roj carbon steel feem ntau nyuaj vim tias nws muaj cov pa roj carbon ntau dua, txawm tias qhov downside yog tias nws nyiam xeb.
Tau kawg, qhov tseeb hardness yuav nyob ntawm qib, thiab koj yuav tsum nco ntsoov tias nws tsis yog qhov siab dua qhov hardness zoo dua, vim tias cov khoom siv tawv dua txhais tau tias nws yooj yim dua rau kev tawg, qhov qis dua hardness ntau dua thiab tsis tshua tawg.
