Stainless Hlau Poob Wax Castingmaterial Classification

Nyob rau hauv layman cov ntsiab lus, stainless hlau yog hlau uas tsis yooj yim rau xeb. Qhov tseeb, qee cov hlau stainless muaj ob qho tib si xeb thiab acid tsis kam (corrosion resistance). Cov xeb thiab corrosion kuj ntawm cov hlau tsis muaj hlau yog vim muaj cov chromium-nplua nuj oxide zaj duab xis (passivation zaj duab xis) ntawm nws nto. Qhov no xeb kuj thiab corrosion kuj yog txheeb ze. Kev ntsuam xyuas qhia tau hais tias qhov kev tiv thaiv corrosion ntawm hlau hauv cov xov xwm tsis muaj zog xws li huab cua thiab dej thiab hauv oxidizing media xws li nitric acid nce ntxiv nrog rau qhov nce ntawm cov dej chromium hauv cov hlau. Thaum cov ntsiab lus chromium nce mus txog ib feem pua, qhov corrosion kuj ntawm hlau tshwm sim. Kev hloov pauv, uas yog, los ntawm yooj yim rau xeb kom tsis yooj yim rau xeb, los ntawm corrosion-resistant mus corrosion-resistant. Muaj ntau txoj hauv kev los faib cov hlau tsis huv. Raws li cov qauv ntawm chav tsev kub, muaj martensitic, austenitic, ferritic thiab duplex stainless hlau; Raws li cov tshuaj muaj pes tsawg leeg, nws tuaj yeem muab faib ua chromium stainless hlau thiab chromium-nickel stainless hlau. Loj loj; Raws li kev siv, muaj nitric acid-resistant stainless hlau, sulfuric acid-resistant stainless hlau, seawater-resistant stainless hlau, thiab lwm yam., raws li hom corrosion kuj, nws yuav muab faib ua pitting-resistant Intergranular corrosion-resistant. stainless hlau, thiab lwm yam; Raws li cov yam ntxwv ua haujlwm, nws tuaj yeem muab faib ua cov hlau tsis muaj hlau nplaum, cov hlau tsis muaj hlau tsis muaj hlau, tsis tshua muaj hlau stainless hlau, siab zog stainless hlau thiab lwm yam. Vim nws zoo heev corrosion kuj, formability, compatibility thiab toughness nyob rau hauv ib tug dav kub ntau yam, stainless hlau tau lug siv nyob rau hauv hnyav kev lag luam, lub teeb kev lag luam, niaj hnub kev lag luam thiab lub tsev kho kom zoo nkauj industries. Daim ntawv thov.

1. Austenitic stainless hlau

Stainless hlau nrog austenitic qauv ntawm qhov kub thiab txias. Thaum hlau muaj li ntawm 18 feem pua ​​​​Cr, 8 feem pua ​​~ 10 feem pua ​​Ni, thiab li ntawm 0.1 feem pua ​​C, nws muaj ib tug ruaj khov austenite qauv. Austenitic chromium-nickel stainless hlau suav nrog cov paub zoo 18Cr-8Ni hlau thiab siab Cr-Ni series hlau tsim los ntawm kev nce cov ntsiab lus ntawm Cr thiab Ni thiab ntxiv Mo, Cu, Si, Nb, Ti thiab lwm yam ntawm lub hauv paus no. Austenitic stainless hlau yog cov hlau tsis muaj hlau nplaum thiab muaj qhov toughness thiab plasticity, tab sis nws lub zog tsawg, nws tsis tuaj yeem ntxiv dag zog rau nws los ntawm kev hloov pauv theem, thiab nws tsuas tuaj yeem ntxiv dag zog los ntawm kev ua haujlwm txias. Xws li ntxiv S, Ca, Se, Te thiab lwm yam, nws muaj kev ua haujlwm zoo. Ntxiv rau qhov kev tiv thaiv corrosion ntawm oxidizing acid nruab nrab, hom hlau no tuaj yeem tiv thaiv corrosion ntawm sulfuric acid, phosphoric acid, formic acid, acetic acid, urea, thiab lwm yam yog tias nws muaj cov ntsiab lus xws li Mo thiab Cu. Yog tias cov pa roj carbon ntsiab lus hauv hom hlau no tsawg dua 0.03 feem pua ​​lossis muaj Ti thiab Ni, nws qhov kev tiv thaiv rau intergranular corrosion tuaj yeem txhim kho tau zoo. High-silicon austenitic stainless hlau nrog concentrated nitric acid muaj corrosion kuj zoo. Vim nws cov khoom siv dav thiab zoo, austenitic stainless hlau tau siv dav hauv txhua qhov chaw ntawm lub neej.

2. Ferritic stainless hlau

Stainless hlau tsuas yog tsim los ntawm ferrite nyob rau hauv lub xeev siv. Cov ntsiab lus chromium nyob nruab nrab ntawm 11 feem pua ​​​​thiab 30 feem pua ​​​​, thiab nws muaj lub cev-centered cubic crystal qauv. Hom hlau no feem ntau tsis muaj nickel, thiab qee zaum muaj me me ntawm Mo, Ti, Nb thiab lwm yam. Hom hlau no muaj cov yam ntxwv ntawm cov thermal conductivity loj, me me expansion coefficient, zoo oxidation tsis kam, thiab zoo heev kev nyuaj siab corrosion kuj. , Qhov chaw corroded los ntawm dej vapor, dej thiab oxidizing acid. Hom hlau no muaj qhov tsis zoo xws li cov yas tsis zoo, txo qis tom qab vuam plasticity thiab corrosion kuj, uas txwv nws daim ntawv thov. Kev siv cov cuab yeej siv hluav taws xob tawm ntawm lub cub tawg (AOD lossis VOD) tuaj yeem txo cov ntsiab lus sib txawv xws li carbon thiab nitrogen, yog li ua rau hom hlau no tau siv dav.

3. Austenite-ferritic duplex stainless hlau

Nws yog stainless hlau nrog austenite thiab ferrite qauv txhua tus accounting txog ib nrab. Hauv cov ntsiab lus C tsawg, cov ntsiab lus Cr yog 18 feem pua ​​~ 28 feem pua, thiab Ni cov ntsiab lus yog 3 feem pua ​​~ 10 feem pua. Qee cov hlau kuj muaj Mo, Cu, Si, Nb, Ti, N thiab lwm yam alloying. Hom hlau no muaj cov yam ntxwv ntawm ob qho tib si austenitic thiab ferritic stainless hlau. Piv nrog rau ferrite, nws muaj ntau dua plasticity thiab toughness, tsis muaj chav kub brittleness, thiab ho txhim kho intergranular corrosion kuj thiab vuam kev ua tau zoo. Muaj 475 degree brittleness thiab siab thermal conductivity ntawm ferritic stainless hlau, thiab nws muaj cov yam ntxwv ntawm superplasticity. Piv nrog austenitic stainless hlau, nws muaj lub zog siab thiab txhim kho kev ua haujlwm zoo rau intergranular corrosion thiab chloride stress corrosion. Duplex stainless hlau muaj zoo heev pitting corrosion kuj thiab kuj yog ib tug nickel-txuag stainless hlau.

4. Martensitic stainless hlau

Cov hlau tsis muaj hlau uas nws cov khoom siv kho tshuab tuaj yeem hloov kho los ntawm kev kho cua sov, nyob rau hauv layman cov ntsiab lus, yog ib hom hardenable stainless hlau. Cov qib raug yog Cr13 hom, xws li 2Cr13, 3Cr13, 4Cr13 thiab lwm yam. High hardness tom qab quenching, sib txawv tempering kub muaj sib txawv zog thiab toughness ua ke, feem ntau yog siv rau chav turbine hniav, tableware, phais instruments. Raws li qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg, martensitic stainless hlau tuaj yeem muab faib ua martensitic ferrochromium thiab martensitic ferronickel. Raws li cov qauv sib txawv thiab ntxiv dag zog, nws tuaj yeem muab faib ua martensitic stainless hlau, martensite thiab semi-austenite (los yog semi-martensite) nag lossis daus hardening stainless hlau thiab maraging stainless hlau.
