Qhov txawv ntawm cov hlau carbon thiab cov hlau tsis xeb yog dab tsi?

Cov hlau carbon, 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 me ntsis silicon, manganese, sulfur thiab phosphorus.

Cov hlau tsis xeb, tseem hu ua stainless acid-resistant steel, hais txog qhov tsis kam ntawm huab cua, pa dej, 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 tiv taus cov tshuaj corrosive media feem ntau hu ua stainless hlau, thiab cov hlau uas tiv taus cov tshuaj chemical media corrosion hu ua acid-resistant steel.

(1) Kev tiv thaiv corrosion thiab abrasion
Cov hlau tsis xeb yog ib qho hlau uas tiv taus xeb los ntawm cov xov xwm tsis muaj zog xws li cua, pa dej, dej thiab cov xov xwm tshuaj lom neeg xws li kua qaub, alkalis thiab ntsev. Thiab qhov kev ua haujlwm no feem ntau yog vim muaj cov khoom tsis xeb - chromium. Thaum cov ntsiab lus chromium ntau dua 12%, qhov chaw ntawm cov hlau tsis xeb yuav tsim ib txheej ntawm zaj duab xis oxidized, feem ntau hu ua zaj duab xis passivation, nrog rau txheej txheej ntawm zaj duab xis oxidized no yuav tsis yooj yim yaj rau hauv qee yam xov xwm, ua lub luag haujlwm zoo cais tawm, muaj zog tiv thaiv corrosion.

Cov hlau carbon yog hais txog cov hlau-carbon alloy uas muaj tsawg dua 2.11% carbon, tseem hu ua carbon steel, nws qhov nyuaj yog siab dua li cov hlau tsis xeb, tab sis qhov hnyav dua, qhov plasticity qis dua, yooj yim rau xeb.

 

(2) cov khoom sib txawv
Cov hlau tsis xeb yog luv rau cov hlau tsis xeb uas tiv taus kua qaub, uas tiv taus huab cua, pa dej, dej thiab lwm yam tsis muaj zog corrosive media lossis nrog cov hlau tsis xeb hu ua stainless hlau; thiab yuav tiv taus cov tshuaj lom neeg corrosive media (acids, alkalis, ntsev thiab lwm yam tshuaj impregnation) corrosion ntawm cov hlau hu ua acid-resistant steel.

Cov hlau carbon yog cov hlau sib xyaw ua ke uas muaj cov pa roj carbon ntawm 0.0218% txog 2.11%. Kuj tseem hu ua cov hlau carbon. Nws kuj muaj me ntsis silicon, manganese, sulfur, thiab phosphorus.

 

(3) Tus nqi
Lwm qhov tseem ceeb uas yuav tsum xav txog yog qhov sib txawv ntawm tus nqi ntawm cov hlau carbon thiab cov hlau tsis xeb. Txawm hais tias cov hlau sib txawv muaj tus nqi sib txawv, cov hlau tsis xeb feem ntau kim dua li cov hlau carbon, feem ntau yog vim muaj ntau yam khoom sib xyaw, xws li chromium, nickel, thiab manganese, rau cov hlau tsis xeb.

Piv rau cov hlau carbon, cov hlau stainless muaj ntau cov hlau sib xyaw ua ke thiab kim dua piv rau cov hlau carbon. Ntawm qhov tod tes, cov hlau carbon feem ntau muaj cov hlau thiab carbon pheej yig. Yog tias koj muaj nyiaj tsawg rau koj qhov project, cov hlau carbon yuav yog qhov kev xaiv zoo tshaj plaws.

 
Qhov twg nyuaj dua, hlau lossis carbon hlau?

Cov hlau carbon feem ntau nyuaj dua vim tias nws muaj cov pa roj carbon ntau dua, txawm hais tias qhov tsis zoo yog tias nws nyiam xeb.

Tau kawg qhov nyuaj yuav nyob ntawm qib, thiab koj yuav tsum nco ntsoov tias nws tsis yog qhov nyuaj siab dua uas zoo dua, vim tias cov khoom siv tawv dua txhais tau tias nws yooj yim tawg, thaum qhov nyuaj qis dua yuav ruaj khov dua thiab yuav tsis tawg.
