Mechanical Properties ntawm Stainless Hlau Screws

Mechanical Properties ntawm Stainless Hlau Screws
Cov cuab yeej cuab tam ntawm txoj cai stainless hlau screws yog qhov tseem ceeb thaum koj xav xaiv qhov zoo tshaj plaws. Kuv ua tib zoo kawm cov lus qhia ntawm cov khoom siv no kom ntseeg tau tias cov ntsia hlau uas kuv xaiv yuav tsis cia kuv poob thaum nws tseem ceeb. Cia peb ua tib zoo saib nws cov khoom tseem ceeb: tensile lub zog, tawm lub zog, hardness, thiab corrosion kuj.

3.1 Tensile zog
3.1.1 Tensile Strength yog dab tsi?
Lub zog tensile hais txog qhov siab tshaj plaws tensile kev nyuaj siab uas cov khoom tuaj yeem tiv taus yam tsis muaj kev tawg. Qhov no yog hais txog lub zog rub tawm uas lub hau ntswj tuaj yeem tiv taus ua ntej tawg.

3.1.2 Qhov tseem ceeb ntawm Screws
Rau cov ntsia hlau, lawv lub zog tensile siab pab lawv dais cov khoom hnyav yam tsis muaj kev tawg. Yog tias koj tab tom tsim ib yam dab tsi uas yuav tsum tau hnyav, cov khoom siv no yuav ua tau raws li koj xav tau.

3.1.3 Tensile Lub zog ntawm cov qib stainless hlau sib txawv
Cia peb saib ntawm lub zog tensile ntawm qee cov qib stainless hlau siv los ua cov ntsia hlau:

Nws ua raws li cov duplex stainless hlau xws li 2205 muaj cov ntawv thov uas lawv muaj zog tensile siab dua austenitic stainless hlau. Kuv nyiam siv duplex lossis martensitic stainless hlau screws thaum kuv xav tau lub zog siab tshaj plaws.

3.2 Yield zog
3.2.1 To taub Yield Strength
Qhov kev ntxhov siab uas cov khoom pib deform mus tas li yog lub zog tawm los, uas yog lub ntsiab lus ntawm cov ntsia hlau khoov thiab tsis rov qab los.

3.2.2 Qhov tseem ceeb ntawm cov khoom muaj zog rau cov ntsia hlau
Vim lub zog muaj zog, lub hau ntswj tuaj yeem tiv taus ntau dua ua ntej nws pib deform. Qhov no yog qhov tseem ceeb rau cov ntawv thov uas cov ntsia hlau xav tau kom nws cov duab thaum muaj kev ntxhov siab.

3.2.3 Sib piv ntawm Yield Strength ntawm Txhua Qib
Ntawm no yog qhov sib piv ntawm yield zog:

Koj yuav pom tias lub zog tawm los ntawm duplex stainless hlau yog ntau dua. Thaum qhov kev pheej hmoo ntawm deformation siab dua, qib xws li 2205 yuav yog qhov kev xaiv zoo tshaj plaws.

3.3 Hardness
3.3.1 Defining hardness
Tsis yog - lub cim xeeb tsis hloov pauv yog yam ntxwv los ntawm kev tiv thaiv khawb thiab indentation, uas yog hardness. Lub hardness ntawm cov ntsia hlau txiav txim siab qhov℃ntawm hnav ntawm cov xov.

3.3.2 Cov nyhuv ntawm cov ntsia hlau ua haujlwm
Qhov nyuaj ntawm cov ntsia hlau, qhov hnav ntau dua - nws yog resistant, thiab yog li tsim nyog rau cov ntawv thov uas yuav tsum tau rov sib dhos thiab disassembly.

3.3.3 Hardness theem ntawm txhua qib
Cia peb saib ntawm Rockwell hardness (HRC) qhov tseem ceeb:

Cia peb saib ntawm Rockwell hardness (HRC) qhov tseem ceeb:

Austenitic 400 qib steel yog softer dua li martensitic 420 qib steel. Yog hais tias kuv xav tau ib tug hnav resistant ntsia hlau kuv yuav xav txog ib tug martensitic stainless hlau.

3.4 Corrosion tsis kam

3.4.1 corrosion kuj yog dab tsi?
Qhov ntawd yog lub tswv yim ntawm kev tiv thaiv corrosion, uas yog hais txog lub peev xwm ntawm cov khoom siv kom tsis txhob muaj kev puas tsuaj los ntawm oxidation lossis lwm yam tshuaj lom neeg. Nyob rau hauv lwm yam lus, yuav ua li cas resistant yog cov ntsia hlau rau xeb?

3.4.2 Lub luag haujlwm hauv lub neej ntawm cov ntsia hlau
Rau cov ntsia hlau uas xav tau kev tiv thaiv ib puag ncig hnyav, lawv xav tau kev tiv thaiv corrosion siab heev los tswj lawv txoj kev ncaj ncees lub sijhawm. Tsis muaj leej twg xav rusty screws ua tsis tiav hauv ib qhov project!

3.4.3 Ntau qib ntawm corrosion kuj
Qhov qeb duas ntawm cov qib sib txawv yog raws li hauv qab no:

Nov yog yuav ua li cas cov qhab nia sib txawv:

Austenitic thiab duplex stainless hlau muab kev tiv thaiv corrosion zoo dua. Rau thaj chaw marine thiab acidic, kuv nyiam xaiv qib 316 lossis 2205 duplex stainless hlau screws.

3.4.4 Cov yam ntxwv cuam tshuam rau Corrosion Resistance
Muaj ntau yam cuam tshuam rau corrosion kuj:

Tshuaj muaj pes tsawg leeg: Cov ntsiab lus xws li chromium thiab molybdenum txhim khu kev tiv thaiv.

Kev kho deg: Smoother nto txo ​​qhov kev pheej hmoo ntawm corrosion.

Ib puag ncig tej yam kev mob: raug cov tshuaj chlorides, acids, los yog cov hauv paus yuav ua rau muaj kev pheej hmoo ntawm corrosion.

Nws pab kuv xaiv cov kev xaiv zoo dua thaum xaiv cov ntsia hlau kom ua tiav kuv lub hom phiaj hauv qhov chaw nyuaj.
