Alloy Steel vs. Carbon Steel
Hauv cov hlau alloy, cov hlau alloy yog cov khoom siv tseem ceeb. Hauv carbon steel, carbon yog qhov tseem ceeb ntawm cov khoom. Alloy steels yog qhov nyuaj los tuav thaum ua haujlwm. Cov pa roj carbon steel yog yooj yim los tuav thaum ua haujlwm. Alloy steels yog kim heev vim qhov sib txawv proportions ntawm alloying ntsiab. Cov pa roj carbon steel tsis tshua kim vim tias nws tsuas muaj cov lej ntawm lwm cov ntsiab lus. Alloy steel feem ntau yog hais txog cov hlau vim nws muaj ntau yam sib txawv alloying ntsiab. Cov pa roj carbon steel kuj tseem tuaj yeem hu ua hlau vim tias nyob rau hauv cov hlau hlau no kuj sib xyaw nrog lwm cov khoom.
Muaj cov kab hlau rhuav tshem cov ntsiab lus hauv carbon hlau. Cov ntsiab lus alloying tuaj yeem yog sulfur, silicon, thiab lwm yam Carbon steel feem ntau muab faib ua ob hom: ib qho yog carbon steel siab, lwm yam yog cov hlau tsis muaj carbon. Yog tias cov pa roj carbon ntau hauv cov hlau, nws yuav nthuav tawm cov khoom sib txawv, xws li kev hloov pauv tsis zoo thiab cov ntsiab lus melting tsawg. Cov pa roj carbon steel tau hais tias yog cov hlau me me lossis cov hlau me me yog tias cov ntsiab lus carbon nyob nruab nrab ntawm {{0}}.05 feem pua thiab 0.25 feem pua.
Vim nws cov ntsiab lus tsis tshua muaj carbon, cov hlau yog siab hlau, uas corrodes thaum sab laug nyob rau hauv ib qho chaw ntub dej. Cov pa roj carbon steel nrog cov ntsiab lus siab carbon muaj txog {{{0}}}.6 feem pua rau 1.0 feem pua carbon compounds thiab txog 0.9 feem pua cov ntsiab lus alloying. High carbon steel yog ib qho nyuaj heev thiab tsis yooj yim rau siv.
Thiab cov cuab yeej vaj siv ntau dua yog 65Mn steel. Vim tias 65Mn steel lub zog. Hardness, elasticity thiab hardenability yog zoo dua li cov hlau zoo tib yam. Nws muaj qhov nyiam ntawm overheating rhiab heev thiab tempering brittleness, thiab nyiam ntawm kev tawg tsim hauv dej quenching. Lub machinability ntawm lub xeev annealed yog ncaj ncees, lub txias deformation plasticity yog tsawg, thiab cov weldability tsis zoo. Qhov decarbonization nyiam ntawm qhov chaw yog me dua li ntawm silicon steel.
Siv cov pa roj carbon steel 65MN tuaj yeem ua rau lub hardness mus txog 57HRC, tab sis kuj muaj qee yam elasticity, yooj yim los tsim ntau yam duab.
Piv txwv li, peb cov cuab yeej ua liaj ua teb Feem ntau lub taub hau yog ua los ntawm cov khoom siv carbon steel.Yog vim nws muaj qhov zoo hauv qab no:
Ntau cov ntaub ntawv raw, yooj yim rau kev yuav, tuaj yeem ua tau raws li cov khoom loj, thiab ua tau raws li lub peev xwm loj ntawm peb lub tuam txhab.
Kev ua haujlwm ruaj khov, tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm lub vaj cuab yeej kev lag luam hardness, thiab muaj zog stability, zoo hardness, tab sis kuj zoo toughness thiab ductility.
Vim nws qhov toughness thiab ductility, nyob rau hauv cov txheej txheem ua, nws yog yooj yim rau nias rau hauv peb cov duab nyiam.
