440 steel - insimbi. Steel 440: iimpawu

Steel ebizwa inamehlo zentsimbi kunye carbon. Iindidi zezinto zokufunda ayixhomekekanga ngokusebenzisa umlinganiselo ngeekhomponenti ezingundoqo, yaye ngokwesiseko ukungcola kunye nezongezelelo yokunikwa imveliso iimpawu kunye neempawu ezahlukeneyo.

Iintlobo ensimbi, ngokungqinelana nomgaqo-nkqubo amaxabiso lungohlulwa lube nomnye, cheap, ethandwayo yaye kubize. Konke kuxhomekeke injongo iingxaki eziphathekayo imveliso yawo. Ngaphezu koko, akukho ingxubevange elungileyo okanye embi ngokukodwa, njengoko izinto esebenzayo liquka oluntsonkothileyo iimpawu ezidibana iimeko ezithile. Ngokukhethekileyo, kunokuthi kubonwe ukuba siqwalasela, umzekelo, 440 ngentsimbi.

izakhi steel

steel loMgangatho kufanele kuhambisane ngaxeshanye ukunxiba ukuxhathisa, ubulukhuni, luthambe, ductility, ubulukhuni, unyamezelo kunye nokukwazi umhlwa bukhali. Ukuziqhelisa, phantse zonke ezi mihlaba zichasene omnye komnye. Enye yezona iinkalo ziphambili ingxubevange, linoxanduva ngenxa yokuqaqadeka nokoma, le carbon. Kuba iikhompawundi enesiqulatho eziphakamileyo oko kuquka abo apho xi olunikeziwe element yemichiza mkhulu kwe-0.5%. Nxiba impahla bokuxhathisa kwaye olungaka ephantsi umhlwa olunikwa chrome ngentsimbi. Ukuba inqanaba mkhulu kwe-13%, oku iimveliso steel stainless.

ubukhulu Iinkozo, amandla, ukuqina unika ingxubevange lwe manganese. Lusetyenziswa inyathelo yacaca kunye kaloliwe. Oku njalo-ebizwa ngokuba intsimbi abulawe.

Ukuba imveliso kulo mbandela khange zaqina ndikwabuthathaka ukanti abanganyangekiyo bubushushu, a ephindeneyo molybdenum longeziwe. Kulo mzekelo, ingxubevange kuthiwa air-bungacinywa.

Kuyanceda ukunciphisa ingozi nokumelana kwaye unika nobulukhuni nickel. Nqaba Property ibonelela lesilicon eziphathekayo. Tungsten kunye vanadium ingxubevange unika amandla ixesha elide.

Features grade steel 440

440 inxulumene izinto insimbi. Oku kusetyenziswa ikakhulu ngenxa nokuveliswa nezitshetshe, izakhiwo zokwakha. Olona phawu olwahlula le intsila iyamelana umhlwa kunye namandla eliphezulu. Kwakhona kolu ngcelele ukugqithisela ukumelana neemeko zokusingqongileyo, amanzi, ukutya, asidi buthathaka kunye alkalis.

Steel grade 440 iquka zenyathi 440A, 440B, 440C, kwaye 440A series - ezinye lithambile yaye 440C - nzima. Nangona kunjalo, le ethile le ubu 440C kunye nokumelana asezantsi noko ukuba nomhlwa ngokunxulumene 440A kunye 440B. Kubonakala ukuba umhlwa kunokwenzeka kwi qha elide ngamanzi okanye imidiya ndlongondlongo. Nangona iipropati ezongeziweyo, mhlwa zothintelo, unika le intsila ngenxa kumphezulu kakuhle egudisiweyo.

Akuyi Kucetyiswa ukuba usebenzise 440 sentsimbi kubushushu ngaphezu nolophu ngexesha abahambahambayo, ekubeni kule meko iimpawu mechanical ye ingxubevange ezilahlekileyo.

Le khemikhali Ukubunjwa ngentsimbi 440

Steel 440, iimpawu zazo zixhomekeke ngqo kwi ekwakhiweni imichiza, ngokutsho series, iqulathe izinto eziqulathwe kule theyibhile ingezantsi.

Njengoko le theyibhile ibonisa, isiqulatho liphantsi carbon ka 440A series, enyangweni - 440C, oko kukuthi, i-brand yakutshanje womelele ngakumbi onke, kwaye leyo, ukumelana kakhulu umhlwa. Nangona zonke uthotho uphawu umgangatho noko ophezulu kunye transfer umthwalo elungileyo.

Iimpawu zomzimba kunye nonyango thermal ngentsimbi stainless 440

Steel 440 parameters Iimpawu zomzimba ngenxa series A, B no C has oku kulandelayo:

• izinto mninzi - 7650 kg / cu. m;
• modulus - 200 uTsvangirai;
• conductivity thermal - 242 W / m kbp;.
• umthamo ethile ubushushu - 460 J / kg.kb;.
• electric resistivity - 600.

Ukuqina ngensimbi 440 yahluka phakathi kweeyunithi 56-58.

I-avareji Ukwandiswa lomlingani thermal, nto leyo ngee / m / C isidanga mm kwi 440A series - 10.1; 440B - 10.3; 440C - 11.7.

unyango nokuvutha kwale nto udlula la manyathelo alandelayo:

• annealing;
• icima;
• iholide.

Annealing lwenzeka kwi lobushushu + 850-900 degrees Celsius, elandelwa unciphiso rhoqo ukuya _600. Ukupholisa kwenzeka ngokusebenzisa indlela moya. Emva koko - Inkqubo damped annealing kwi izidanga 735-785 nokupholisa ezikweni.

Tempering oluqhutywa phaya + 1010-1065 degrees Celsius. Icima - ukusebenzisa ioli efudumeleyo okanye nomoya.

Ikhefu udlula e + 150-370 degrees, khon 'ukuze impahla unikwa nobulukhuni kuyimfuneko. Phakathi iintlobo izinto ezifana nesinyithi 440, iimpawu amanyathelo lomatshini ngeyona kwibanga 440C. Le ingxubevange yeyona eninzi kakhulu kwaye athembekile. Le ichaza umgangatho iimveliso esemgangathweni.

Izicelo Steel 440

440 steel stainless ikakhulu isetyenziselwa ukwenziwa izigalo.. Uqasha ingxubevange onikwa ekwakheni iimveliso ofunwa okanye kusitsha.

Sheets kweemveliso ezigqityiweyo ziveliswa kunye okusuka mm-4 ukuya ku-50. 440 steel ayifuni zokufudumeza ezongezelelweyo kunye nonyango nobushushu obuninzi welding yakhe. ingxubevange lula kwaye zithembeke ekuveliseni iibheringi, amaqhekeza ipipi ezifakwe.

440A brand kuvelisa nezitshetshe nzima ngakumbi, kuquka kwamanzi, ukuzingela. Yabe thotho 440C kufuneka iipropati ukusika egqwesileyo kwaye baziswa omhle ekuloleni, ngoko oku sobhedu isetyenziselwa ukuvelisa izixhobo ahlabayo elite.

Kufuneka wazi xa uthenga imela enombhalo "440" asetyenziswa intsila engabizi - 440A. Kwimeko iikhompawundi abizayo 440B kunye nabenzi 440C kusoloko sinikele ingqalelo kuyo.

enye brand

Kukho intaphane yemiyinge ezizezinye, leyo kufakwe le ingxubevange. Umzekelo, uthotho lwe 440A / B anazo iimpawu ezongezelelweyo aphucula nokumelana. Steel 440F uye workability ephakamileyo kwindawo amandla efanayo. Enasilela ngayo iimpawu zabo yebanga yobulukhuni 420. 416 manqaku enzelwe workability eliphezulu kodwa nokuthembeka asezantsi.

Ukuba wenza iimela ukusuka 440A brand kunye analogs yayo, ezi mveliso alungele ukusetyenziswa yonke imihla. Nangona, kubalulekile ukuba uthathe ingqalelo umgangatho icima. ukuzabalaza kakuhle kwinkqubo kule nkampani Kor. Inkampani "Randall" ikakhulu uvelisa iincakuba zentsimbi 440B.
