S30C - Carbon Steel: Cov ncauj lus kom ntxaws

S30C, ib hom carbon steel, tuav qhov tseem ceeb hauv ntau yam kev lag luam vim nws cov khoom tshwj xeeb thiab cov yam ntxwv.

Hais txog cov tshuaj muaj pes tsawg leeg, S30C muaj cov pa roj carbon tsawg, feem ntau nyob ib ncig ntawm 0.27% txog 0.33%. Cov ntsiab lus carbon no muab cov hlau zoo sib npaug ntawm lub zog thiab ductility. Nws kuj tseem suav nrog lwm cov ntsiab lus alloying xws li manganese, silicon, thiab cov kab ntawm leej faj thiab phosphorus hauv cov nqi tswj. Cov ntsiab lus no pab txhawb rau cov hlau tag nrho cov khoom siv kho tshuab thiab metallurgical, txhim kho nws cov txheej txheem thiab kev ua haujlwm.

Hais txog cov khoom siv kho tshuab, S30C nthuav tawm lub zog tensile zoo, tso cai rau nws tuaj yeem tiv taus qhov tseem ceeb ntawm rub lossis ncab quab yuam yam tsis tau tawg yooj yim. Nws kuj muaj qhov tsim nyog theem ntawm cov khoom muaj zog, qhia txog kev ntxhov siab uas cov khoom yuav pib deform plastically. Cov hlau qhia tau hais tias zoo ductility, uas txhais tau hais tias nws tuaj yeem deformed lossis khoov rau qee yam tsis muaj kev tawg, ua rau nws tsim nyog rau ntau yam kev tsim khoom xws li forging, dov, thiab machining. Nws qhov toughness kuj tseem ceeb, ua kom nws nqus tau lub zog thiab tiv thaiv kev cuam tshuam tam sim ntawd.

Hauv kev tsim khoom lag luam, S30C tau siv dav hauv kev tsim cov khoom xws li shafts, gears, thiab bolts. Nws cov machinability yog qhov zoo, uas txhais tau hais tias nws tuaj yeem txiav tau yooj yim, drilled, thiab zoo li tus rau hauv cov ntawv xav tau siv cov cuab yeej machining. Cov cuab yeej no pab txo cov sij hawm tsim khoom thiab cov nqi. Tsis tas li ntawd, nws tuaj yeem raug kho cua sov los txhim kho nws cov khoom siv kho tshuab. Piv txwv li, los ntawm cov txheej txheem quenching thiab tempering, hardness thiab lub zog ntawm S30C tuaj yeem hloov kho kom tau raws li cov kev thov tshwj xeeb.
S30C carbon steel kuj paub txog nws cov weldability zoo. Txawm li cas los xij, cov txheej txheem vuam kom raug thiab cov txheej txheem yuav tsum tau ua kom ntseeg tau tias kev ncaj ncees ntawm cov pob qij txha welded. Nws yog ib qho tseem ceeb uas yuav tau xav txog yam xws li preheating thiab tom qab vuam cua sov kho kom tsis txhob tawg thiab ua kom pom cov khoom siv kho kom zoo hauv thaj chaw welded.
Zuag qhia tag nrho, S30C - carbon steel yog ntau yam khoom siv thiab txhim khu kev qha uas muaj kev sib xyaw ua ke uas ua rau nws tsim nyog rau ntau yam kev siv hauv engineering thiab kev lag luam. Nws muaj peev xwm ua tiav, kho cua sov, thiab welded, nrog rau nws cov khoom siv tau zoo, ua rau nws yog qhov kev xaiv tseem ceeb rau ntau tus neeg tsim khoom thiab cov chaw tsim khoom. Txawm hais tias nyob rau hauv lub tsheb, tshuab, lossis lwm yam haujlwm, S30C tseem ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom zoo thiab ruaj khov.
