K A32 Steel Phaj

 

 

Mechanical Properties

 

Yield zog

 

Thaum lub sij hawm nruab nrab - kub laus ntawm 150 - 250 degree, cov hlau alloy nyob rau hauv KA32 steel yuav precipitate ntawm tus nqi tsim nyog los tsim precipitates. Cov precipitates no tuaj yeem cuam tshuam qhov kev txav ntawm dislocations. Piv txwv li, nyob ib ncig ntawm 200 degree rau li 15 teev ntawm kev laus, raws li cov precipitates tsim thiab loj hlob, dislocations yuav tsum tau bypass cov precipitates thaum lub sij hawm txav, uas yuav tsum tau ntau zog thiab yog li no ho nce cov khoom yield zog. Piv nrog rau KA32 steel yam tsis muaj kev laus kev kho mob, lub zog tawm los yuav nce li ntawm 30% - 50%. Qhov no ua rau cov hlau zoo dua tuaj yeem tiv taus cov yas deformation thaum raug rau sab nraud quab yuam thiab txhim kho kev ruaj ntseg ntawm cov qauv.

 

Tensile zog

 

Thaum lub sij hawm nruab nrab - qhov kub thiab txias txheej txheem, ntxiv rau kev txhim kho lub zog tawm los, lub zog tensile kuj yuav txhim kho. Vim muaj cov precipitates, cov khoom tuaj yeem tiv taus lub zog tensile ntau dua hauv kev sim tensile. Cov precipitates tuaj yeem ua raws li lub zog txhawb zog thiab tiv thaiv kev tsim thiab nthuav tawm ntawm micro - tawg hauv cov khoom. Tom qab kev laus hauv qhov kub thiab txias, lub zog tensile yuav nce li ntawm 20% - 40%. Piv txwv li, KA32 steel cov khoom siv hauv kev tsim cov nkoj, tom qab nruab nrab - kub kev kho mob, tuaj yeem tiv taus cov kev cuam tshuam sab nraud ntau dua xws li cua thiab nthwv dej thiab txo qhov kev pheej hmoo ntawm kev puas tsuaj.

 

 

 

Lub cev muaj zog

 

Kev hloov ceev

 

Thaum lub sij hawm kev laus ntawm 150 - 250 degree , vim lub rearrangement ntawm atoms thiab tsim precipitates, qhov ceev ntawm KA32 steel yuav hloov me ntsis. Feem ntau hais lus, qhov ceev ntawm cov precipitates txawv ntawm cov khoom siv matrix. Thaum cov precipitates tsim, tag nrho qhov ntom ntawm cov khoom yuav nce los yog txo me ntsis, tab sis qhov kev hloov no yog me ntsis, feem ntau tsawg dua ib - txhiab. Hauv feem ntau cov ntawv thov, qhov kev hloov ceev no muaj kev cuam tshuam me ntsis ntawm kev siv cov khoom siv. Piv txwv li, hauv kev tsim vaj tsev lossis cov khoom siv tshuab, qhov kev hloov pauv me ntsis no yuav tsis muaj qhov cuam tshuam tsis zoo rau lawv qhov kev ua tau zoo.

Coefficient ntawm Thermal Expansion Hloov

 

Nruab nrab - kub laus yuav hloov cov coefficient ntawm thermal expansion ntawm KA32 steel. Lub thermal expansion yam ntxwv ntawm cov tshiab - tsim precipitates thiab cov matrix yog txawv, uas yuav ua rau ib tug hloov nyob rau hauv expansion tus cwj pwm ntawm cov khoom thaum nws yog rhuab. Tom qab kev laus nyob rau hauv lub caij ntuj no kub, lub coefficient ntawm thermal expansion yuav txo tau li ntawm 10% - 20%. Rau qee qhov kev siv nrog cov kev xav tau siab rau qhov tseeb qhov tseeb, xws li cov khoom siv precision, qhov kev hloov pauv ntawm cov coefficient ntawm thermal expansion yuav tsum tau txiav txim siab kom tsis txhob muaj kev cuam tshuam rau qhov tseeb ntawm qhov chaw hauv qhov kub thiab txias - hloov ib puag ncig.

 

Corrosion Resistance

 

Nruab nrab - kub laus tuaj yeem txhim kho corrosion kuj ntawm KA32 steel. Thaum lub sij hawm cov txheej txheem kev laus, ib tug tuab oxide zaj duab xis yuav raug tsim nyob rau saum npoo ntawm cov hlau los yog cov hlau alloy tej zaum yuav enriched rau saum npoo. Piv txwv li, tom qab kev laus ntawm 180 degree rau 18 teev, qee cov ntsiab lus hlau (xws li chromium, npib tsib xee, thiab lwm yam) yuav diffuse rau saum npoo los tsim cov yeeb yaj kiab tiv thaiv, tiv thaiv kev sib cuag ntawm cov xov xwm corrosive (xws li dej hiav txwv, acidic daws, thiab lwm yam) nrog steel matrix. Nyob rau tib lub sijhawm, cov khoom sib xyaw ua ke sib xyaw ua ke tuaj yeem txo cov kab xeb hauv cov khoom siv thiab txhim kho cov khoom siv corrosion kuj. Qhov no tseem ceeb heev rau KA32 steel qauv siv nyob rau hauv hnyav ib puag ncig xws li marine ib puag ncig.
