Kev siv cov ntaub ntawv kuj tseem ceeb heev rauTsis-Qauv Ntsia Hlau, thiab tusKev Cai Ntsia Hlaucov ntaub ntawv uas yuav siv rau hauv cov ntawv thov sib txawv yog qhov sib txawv, xws li cov qauv kev ua tau zoo ntawm cov khoom sib txawv, thiab lwm yam, raws li covkev hloov tshuabKev tsim tshuaj tshwj xeeb suav nrog cov hlau carbon, hlau Stainless, tooj liab peb yam khoom.
1.Why Xaiv cov roj carbon hlau, hlau hlau, tooj liab?
Carbon Steel: Peb paub qhov txawv ntawm cov hlau tsis tshua muaj carbon, nruab nrab cov hlau thiab cov roj carbon hlau, thiab cov hlau sib nkaws hauv cov pa roj carbon hauv carbon.
(1) Cov roj carbon tsawg C% Cur0.25% feem ntau hu ua A3 steel nyob hauv Suav teb. Cov teb chaws txawv teb chaws tseem yog hu rau 1008, 1015, 1018, 1022, thiab lwm yam xws li 4.8 qib bolts, 4 qib neeg ceev thiabCov screws me meCov. (Nco tseg: 1022 cov khoom siv yog siv rau cov ntsia hlau ntsia.)
(2) Nruab Nrab Carbon Hlau 0.25%
(3) Cov pa roj carbon hlau siab c%> 0.45%. Tam sim no, nws yog qhov tsis siv hauv kev ua lag luam
(4) Alloy Steel: ntxiv cov khoom siv alloy rau qee cov khoom siv tshwj xeeb ntawm cov hlau: xws li 35, 40 chromium molybdenum, scm435, 10b38. Panvo Screws tsuas yog siv scm435 chrome alloy steel, thiab lub ntsiab lus tseem ceeb yog C, Si, MN, P, S, thiab MO.
Carbon Hlau Ntsia HlauMuaj lub zog siab thiab hardness, hnav tsis kam, muaj zog muaj zog, thiab cov nqi lag luam qis. Cov khoom no ua rau cov pa roj carbon hlau ib qho zoo tagnrho rau kev tsim cov khoom ntawm cov txheem.
Tus Hlau Stainless: Qib Kawm Qib: 45, 50, 60, 70, 80
Lub hauv paus tseem ceeb yog Austenite (18% cr, 8% ni), uas muaj cov cua sov tsis kam, zoo corrosion thiab zoo weldability. A1, A2, A4 Martensitic thiab 13% CR muaj kev tsis zoo corrosion tsis kam, siab lub zog thiab kev coj zoo. C1, C2, C4 Ferritic Stainless Hlau. 18% kev chim siab yog qhov zoo dua, thiab cov xeb tsis kam yog muaj zog dua li ntawm martensite. Ntawm tam sim no, cov ntaub ntawv txawv teb hauv kev ua lag luam yog xov xwm Nyiv. Raws li qib, nws tsuas yog muab faib ua Sus302, Sus304, thiab sus316.
Stainless hlau ntsia hlauMuaj kev tiv thaiv corrosion zoo tshaj plaws, tuaj yeem khaws cia rau hauv cov kev mob zoo rau ib puag ncig hnyav, thiab tsis yooj yim rau xeb. Ib qho ntxiv, Stainless Hlau muaj cov yam ntxwv ntawm lub zog siab, zoo nkauj zoo, thiab kev ua tau yooj yim.
Tooj liab: cov siv siv yog tooj dag ... Zinc-coper alloy. H62, H65 thiab H68 tooj liab tsuas yog siv ua cov txheem txheem hauv khw.
Tooj Ntsaws HlauMuaj hluav taws xob zoo, thermal conductivity, corrosion tsis kam thiab ua cov khoom, thiab tuaj yeem welded thiab brazed. Cov khoom siv tau ua rau tooj liab muaj txiaj ntsig hauv lub hwj huam kis, lub cev muaj zog
2 Dab tsi yog qhov sib txawv ntawm cov hlau uas tsis muaj roj thiab cov hlau?
Stainless hlau thiab cov hlau nplaum tseem siv cov ntaub ntawv hlau, thiab ntau tus neeg tsis paub dab tsi txawv ntawm cov hlau uas tsis muaj roj thiab roj carbon hlau.
Dab tsi yog qhov sib txawv ntawm cov hlau uas tsis muaj roj thiab cov hlau? Nyob ntawm lub hom phiaj thiab kev ua tau zoo, feem ntau yog cov sib txawv hauv qab no:
(1) Stainless hlau muaj kev txom nyem thermal conductivity thiab qis elongation vim nws cov txom nyem thermal conductivity thiab elongation, yog li cov kev quab yuam uas yuav tsum tau loj;
(2) piv nrog cov hlau ua hlau, hlau stainless, phaj muaj lub zog muaj zog los thim rov qab thaum khoov;
(3) piv nrog cov hlau hlau, vim qhov qis qis ntawm cov hlau stainless hlau thaum khoov, txwv tsis pub muaj cov kab nrib pleb;
(4) vim lub siab tawv ntawm stainless hlau phaj thiab cov txiaj ntsig tseem ceeb ntawm kev kho cua txias ntawm ntau dua 60hrc yuav tsum tau xaiv, thiab nws cov npoo roughness yuav tsum tau
Ntawm Yuhuang,Tuam Tshoj Ntsia Hlau Chaw Tsim TshuajPeb paub tiasZoo Ntsia HlauCov ntaub ntawv raw yog lub hauv paus rau kev tsim cov khoom zoo. Yog li ntawd, txhuatswjyog ua los ntawm high-zog alloy steel, stainless hlau, stession cov ntaub ntawv uas tau ua tib zoo ua kom paub tseeb tias muaj kev ruaj khov thiab txhim khu kev ua haujlwm ruaj khov thiab txhim khu kev ua haujlwm nyob hauv ib puag ncig. Xaiv Yuhuang screws, koj xaiv impeccable zoo kwv yees.
