ALLOY meej
| chaw ua uas tsis tau haus | Kwv yees li cas | lus piav |
| Ceev | 7.7 ~ 7.8 g / cm * | Qhov no stainless hlau yog nruab nrab - ntom thiab hnyav hnyav. |
| Melting taw tes | 1480 ~ 1530 degree | Lub siab melting taw tes ua rau nws haum rau high- kub ua, tab sis yuav tsum paub txog kev pheej hmoo ntawm kev pheej hmoo ntawm kev tawg. |
| Thermal conductivity | 21.2 W / (MISK K3 (100 ~ 500 DEGREE) | Nws zoo heev thermal conductivity ua nws haum rau cua sov dissipation hauv high - kub cov khoom kub. |
| Linear nthuav cov coefficient | 9.9~11.7x10-6/K | Nws txoj kev nthuav dav thermal los nthuav tawm ua rau nws haum rau ib puag ncig nrog loj hloov hluav taws xob. |
| Resiveivity | {{0 {}} hli3 / m (20 degree) | Nws qhov hluav taws xob tsawg ua rau nws tsis zoo rau qhov siab - hype conductivity. |
| Elastic modulus | 200 GPA (20℃degree) | Nws lub siab rigidity ua rau nws haum rau high {{0} Log cov txheej txheem. |
| Cov Khoom Sib Nqus | Ferromagnetic | Nws tuaj yeem siv rau hauv cov khoom siv hluav taws xob lossis cov ntawv thov uas xav tau kev sib nqus kev nyiam. |
Kev txheeb ze ntawm cov khoom siv neeg kho tshuab
Hardness thiab lub zog:
- Annealed lub xeev hardness tsawg dua los yog sib npaug rau 200 HB;
- Quenched thiab tempered hardness loj dua los yog sib npaug rau 170 HB;
- Tensile lub zog loj dua los yog sib npaug rau 590 MPa.
Thaum tshav kub kub tiv:
- Oxidation tiv taus txog 800 degree;
- Pom zoo cov kev pabcuam txuas ntxiv mus tsawg dua lossis sib npaug li 704 degree.
Applrication
Qib 403 Stainless Hlau Hloov Bar muab cov hardness siab, thiab muaj kev cuam tshuam kub ntau ntxiv raws li nws cov kev siv tshuab thiab kub- kev siv kub. Txawm li cas los xij, nws tsawg corrosion tsis kam yuav tsum tau sau tseg. Thaum xaiv cov khoom siv no, xav txog cov kev ua haujlwm tshwj xeeb los txiav txim siab txog kev kho kom haum cua sov (anealed / quenched thiab tempered) thiab nto tas.
NEEG KHO TSHUAB RAUG SECTOR
1. High -} Kev ntxhov siab tseem ceeb
Cov Kev Siv Raug:Turbine hniav, bearings, zog, bolts / neeg rau, cov khoom sib xyaw.
Qhov Zoo:
- Hardness ncav cuag HRC 20-45 tom qab quenching, tensile lub zog ntau dua los yog sib luag rau 590 MPa, haum rau nrog nrog cuam tshuam cov khoom.
- Cov oxidation zoo ua tsis kam rau hauv qab 800 degree, haum rau high- kub tshuab ib puag ncig.
Kev Kawm Txog Cov Ntaub Ntawv:Lub dav hlau lub cav tawg, Industrial iav reducer zog.
2. Tej cov cuab yeej thiab pwm
- Siv tau hom:Cov cuab yeej ntoo ntoo, ntaus pob zeb tuag, tsim cov pwm hauv cov khoom lag luam qis - corrosion ib puag ncig.
- Txwv tsis pub:Zam kev muaj zog acid / alkali ib puag ncig (pom zoo 304 lossis 420 stainless hlau).
Muaj Khoom Thiab Zog Sua
1. Cov khoom siv petrochemical
- Cov Ntawv Thov:Li qub, piping fittings, tank linings (tsis -} muaj zog corrosive media).
- Qhov Zoo:Tiv taus hydrogen sulfide kev nyuaj siab corrosion, haum rau cov roj thiab roj tshuab cov khoom siv.
- Txwv tsis pub:Zam kev sib cuag nrog cov tshuaj sulfuric acid, hydrochloric acid, thiab lwm yam.
2. Zog thiab Aerospace
- Cov xwm txheej:Kev kub hnyiab rau lub cev qhuav, cov cua sov ua kom haum, hluav taws xob cav qhov chaw.
- Cov yam ntxwv tseem ceeb:Tiv taus siab - kub oxidation (tsawg dua los yog sib npaug ntawm 704℃kev siv), thermal conductivity ntawm 21.2 w / (may) pab txhawb tshav kub.
Automotive Thiab Tsheb Thauj
1. Cov Khoom Siv Hluav Taws Xob
- Cov Ntawv Thov:Tso cov kab mob tso tawm, cov roj Tank nkhaus, satinronizer rings.
- Qhov Zoo:Tiv taus corrosion me me los ntawm cav tso pa tawm, cov khoom sib nqus uas pab txhawb kev sib dhos.
2. Rail tsheb thauj mus los
- Cov Ntawv Thov:High - Ceev RAIR RAIL KEV RAIL (CHRIAL BOLTS (Mild Acid Los nag ib puag ncig).
- Cov ntaub ntawv txheeb xyuas:Shanghai Metro Project siv 403 stainless hlau bolts pom tias tsis muaj corrosion tom qab 5 xyoos.
Kev Tsim Kho Thiab Kho Kom Zoo Nkauj
1. Kho Kom Zoo Nkauj
- Cov Ntawv Thov:Railings, qhov rooj / qhov rai thav duab pob txha pob ntseg.
- Nto Kho:Txhuam / polished tiav ua tiav tau zoo tshaj qib RA0.8μm, resistant rau hauv nroog atmospheric corrosion.
