Kev siv cov ntaub ntawv tseem ceeb heev rautsis yog tus qauv ntsia hlau, thiab covkev cai ntsia hlaucov ntaub ntawv uas yuav siv tau nyob rau hauv ntau daim ntawv thov yog txawv, xws li cov qauv kev ua tau zoo ntawm cov ntaub ntawv sib txawv, thiab lwm yam, raws li covkhw muag khoom tam sim noManufactur mas muaj xws li carbon steel, stainless hlau, tooj liab peb cov ntaub ntawv.
1.Vim li cas thiaj xaiv carbon steel, stainless hlau, tooj liab?
Carbon steel: Peb paub qhov txawv ntawm cov pa roj carbon tsawg, nruab nrab carbon steel thiab siab carbon steel, thiab alloy steel los ntawm tus nqi ntawm cov pa roj carbon steel.
(1) Tsawg carbon steel C% ≤0.25% feem ntau hu ua A3 steel hauv Suav teb. Lub teb chaws txawv teb chaws yog lub hauv paus hu ua 1008, 1015, 1018, 1022, thiab lwm yam. Nws yog tsuas yog siv rau cov khoom uas tsis muaj hardness yuav tsum tau xws li 4.8 qib bolts, 4 qib ceev thiabme me screws. (Ceeb Toom: 1022 cov khoom siv feem ntau yog siv rau cov ntsia hlau.)
(2) Nruab nrab carbon steel 0.25%
(3) High-carbon steel C%> 0.45%. Tam sim no, nws yeej tsis siv nyob rau hauv kev ua lag luam
(4) Alloy steel: ntxiv cov ntsiab lus alloying rau cov pa roj carbon zoo tib yam kom nce qee cov khoom tshwj xeeb ntawm cov hlau: xws li 35, 40 chromium molybdenum, SCM435, 10B38. Panvo screws feem ntau siv SCM435 chrome alloy steel, thiab cov khoom tseem ceeb yog C, Si, Mn, P, S, Cr, thiab Mo.
Carbon steel ntsia hlaumuaj zog thiab hardness, zoo hnav tsis kam, muaj zog plasticity, thiab tus nqi tsim khoom tsawg. Cov khoom no ua rau cov pa roj carbon steel yog cov khoom siv zoo tshaj plaws rau kev tsim cov khoom txheem.
Stainless hlau: kev kawm qib: 45, 50, 60, 70, 80
Cov khoom tseem ceeb yog austenite (18% Cr, 8% Ni), uas muaj cov cua sov zoo, zoo corrosion kuj thiab zoo weldability. A1, A2, A4 martensitic thiab 13% Cr muaj tsis zoo corrosion kuj, siab zog thiab zoo hnav tsis kam. C1, C2, C4 ferritic stainless hlau. 18% Cr chim siab yog zoo dua, thiab corrosion kuj muaj zog dua li ntawm martensite. Tam sim no, cov khoom siv hauv kev lag luam yog cov khoom lag luam Nyij Pooj. Raws li qib, nws feem ntau muab faib ua SUS302, SUS304, thiab SUS316.
Stainless hlau ntsia hlaumuaj kev tiv thaiv corrosion zoo heev, tuaj yeem khaws cia rau hauv qhov chaw zoo rau lub sijhawm ntev hauv qhov chaw hnyav, thiab tsis yooj yim rau xeb. Tsis tas li ntawd, stainless hlau muaj cov yam ntxwv ntawm lub zog siab, zoo nkauj zoo nkauj, thiab ua haujlwm yooj yim.
Copper: Cov khoom siv feem ntau yog tooj dag... Zinc-tooj liab alloy. H62, H65 thiab H68 tooj liab yog siv los ua tus qauv hauv kev ua lag luam.
tooj liab ntsia hlauNws muaj cov khoom siv hluav taws xob zoo, thermal conductivity, corrosion kuj thiab kev ua haujlwm, thiab tuaj yeem welded thiab brazed. Cov khoom no ua rau tooj liab muaj txiaj ntsig hauv kev xa hluav taws xob, lub cev muaj zog
2 Dab tsi yog qhov txawv ntawm stainless hlau thiab carbon hlau?
Stainless hlau thiab carbon hlau kuj yog cov ntaub ntawv hlau, thiab ntau tus neeg tsis paub tias qhov txawv ntawm stainless hlau thiab carbon hlau yuav ua li cas.
Dab tsi yog qhov txawv ntawm stainless hlau thiab carbon hlau? Nyob ntawm lub hom phiaj thiab kev ua tau zoo, feem ntau muaj qhov sib txawv hauv qab no:
(1) Stainless hlau tsis zoo thermal conductivity thiab qis elongation vim nws tsis zoo thermal conductivity thiab elongation, yog li qhov yuav tsum tau deformation quab yuam yog loj;
(2) Piv nrog carbon steel, stainless hlau phaj muaj ib tug muaj zog nyiam rebound thaum khoov;
(3) Piv nrog carbon steel, vim qhov qis elongation ntawm stainless hlau phaj, qhov khoov lub kaum sab xis R ntawm lub workpiece yuav tsum ntau dua li cov pa roj carbon steel thaum khoov, txwv tsis pub muaj qhov ua rau tawg;
(4) Vim lub siab hardness ntawm stainless hlau phaj thiab qhov tseem ceeb ntawm kev ua hauj lwm txias hardening, thaum xaiv compression dabtsi yog khoov cov cuab yeej, cov cuab yeej steel nrog kub kho hardness ntawm ntau tshaj 60HRC yuav tsum tau xaiv, thiab nws nto roughness yuav tsum tau.
Hauv Yuhuang,Tuam Tshoj ntsia hlau manufacturerspeb paub tiashigh-zoo ntsia hlauraw cov ntaub ntawv yog lub hauv paus rau tsim cov khoom zoo heev. Yog li ntawd, txhua tusntsia hlauyog ua los ntawm high-strength alloy steel, stainless hlau thiab lwm yam ntaub ntawv siab heev uas tau ua tib zoo tshuaj xyuas kom paub tseeb tias nws tsis tsuas yog muaj zog load-bearing muaj peev xwm thiab corrosion kuj, tab sis kuj muaj ib tug ruaj khov thiab txhim khu kev qha kev ua hauj lwm nyob rau hauv huab ib puag ncig. Xaiv Yuhuang screws, koj xaiv impeccable zoo guarantee.
