S45C Poob Wax Peev Casting

Khoom Taw Qhia

S45C steel yog ib hom carbon structural steel uas nws cov tshuaj muaj pes tsawg leeg muaj xws li 0.42%-0.48% carbon, 0.6%-0.9% manganese, Tsawg dua lossis sib npaug rau 0.03% silicon, Tsawg dua lossis sib npaug rau 0.035% phosphorus, thiab Tsawg dua lossis sib npaug rau 0.035% sulfur.

Hauv cov hlau, carbon yog ib qho tseem ceeb, uas tuaj yeem cuam tshuam qhov ntim thiab lub cev ntawm cov hlau. Hauv S45C steel, cov ntsiab lus carbon yog 0.42%-0.48%, uas txhais tau hais tias nws yog cov pa roj carbon siab. High carbon steel muaj cov yam ntxwv ntawm siab hardness, siab zog, thiab zoo hnav tsis kam, tab sis tsis tshua muaj elastic modulus thiab cuam tshuam toughness.

Nws yog lwm lub ntsiab lus tseem ceeb, nrog rau cov ntsiab lus ntawm 0.6%-0.9% hauv S45C steel. Germanium tuaj yeem txhim kho lub zog, hardness, thiab hnav tsis kam ntawm cov hlau, thaum tseem txhim kho corrosion kuj. Qhov sib ntxiv ntawm manganese kuj tseem tuaj yeem txhim kho kev ua haujlwm thiab vuam kev ua haujlwm ntawm cov hlau, txo cov quab yuam, thiab txhim kho kev ua haujlwm ntawm kev ua haujlwm txias.

Cov ntsiab lus ntawm cov ntsiab lus xws li silicon, phosphorus, thiab sulfur yog tsawg, thiab tsuas yog cov lej muaj nyob hauv cov tshuaj muaj pes tsawg leeg. Silicon tuaj yeem txhim kho lub machinability thiab hardness ntawm hlau, tab sis ntau dhau ntawm silicon tuaj yeem ua rau brittleness thiab tsis muaj zog ntawm cov hlau. Ob leeg phosphorus thiab sulfur tuaj yeem cuam tshuam rau cov khoom siv kho tshuab thiab weldability ntawm steel. Yog tias cov ntsiab lus siab dhau lawm, nws yuav txo qhov toughness thiab cuam tshuam ntawm cov hlau.

S45C steel yog tag nrho cov hlau zoo li qub tsim los ntawm lub tshuab hluav taws xob, qhib lub siab, lossis cov pa ntshiab oxygen converter steelmaking txoj kev. Cov hlau muaj cov qauv zoo li metallographic thiab tsis muaj qhov tsis xws luag.

Cov ntsiab lus carbon ntawm cov hlau no yog siab dua 0.4%, thiab nws muaj kev hnav zoo heev, tab sis nws cov ductility raug txo, thiab nws yooj yim rau deform thiab tawg tom qab quenching. Yog li ntawd, kev kho cua sov yog ib qho tseem ceeb heev, thiab nws yuav tsum tau txias sai sai tom qab tempering kom tsis txhob temper brittleness. Qhov kev ua tau zoo ntawm hom carbon hlau no tuaj yeem txhim kho los ntawm spheroidizing cov hlau.

Yam ntxwv

Nws yog ib qho nruab nrab-carbon high-zoo steel nrog ntau zog. Vim nws tsis zoo hardenability, nws yog feem ntau siv nyob rau hauv ib tug normalized xeev. Thaum cov txheej txheem kev ua haujlwm siab dua, quenching thiab tempering kho yog siv. Qhov txias deformation plasticity yog nruab nrab, thiab lub machinability ntawm annealing thiab normalizing yog zoo dua li ntawm quenching thiab tempering. Nws yog siv los tsim cov khoom uas muaj lub zog siab, xws li lub zog, ncej, piston pins, thiab lwm yam, nrog rau cov khoom siv, forgings, stamping qhov chaw, bolts, ceev, thiab cov yeeb nkab txuas uas tsis muaj kev ntxhov siab loj.

Siv

S45C poob ciab peev yog dav siv hauv kev tsim khoom thiab cov hlau no muaj cov khoom siv zoo heev. Txawm li cas los xij, qhov no yog nruab nrab-carbon steel nrog kev ua haujlwm tsis zoo. No. 45 steel tuaj yeem hardened rau HRC42 ~ 46. Yog li ntawd, yog hais tias deg hardness yuav tsum tau thiab lub superior mechanical zog ntawm 45 # steel yog xav tau, qhov saum npoo ntawm 45 # steel yog feem ntau carburized thiab quenched, thiaj li hais tias qhov yuav tsum tau deg hardness yuav tau.

Muab cov xwm txheej hardness: 137 ~ 170HBS, 167 ~ 229HBS, 201 ~ 269HBS

Feem ntau hais lus, cov tshuaj muaj pes tsawg leeg ntawm S45C steel ua tau raws li cov qauv ntawm cov hlau dav dav, thiab nws cov ntsiab lus siab carbon thiab manganese muab nws cov yam ntxwv ntawm siab hardness, siab zog, thiab hnav tsis kam. Txawm li cas los xij, nws qhov tsis zoo yog tias nws yooj yim rau harden thaum lub sij hawm ua thermal, yog li tsim nyog preheating thiab annealing yuav tsum tau.
