X2CrNi18-9 belongs rau tus qauv German austenitic stainless hlau, tus qauv siv: DIN 17440-1979
X2CrNi18-9 stainless hlau, tseem hu ua ultra-low carbon stainless hlau, yog ntau yam stainless hlau cov khoom siv dav siv hauv kev tsim cov khoom siv thiab cov khoom uas xav tau kev ua haujlwm zoo tag nrho (corrosion resistance and formability).
Austenitic stainless hlau hais txog stainless hlau nrog cov qauv austenitic ntawm chav tsev kub. Thaum cov hlau muaj li ntawm 18 feem pua Cr, 8 feem pua ~ 25 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 nto moo 18Cr-8Ni steel thiab siab Cr-Ni series steel tsim los ntawm kev nce Cr thiab Ni cov ntsiab lus thiab ntxiv Mo, Cu, Si, Nb, Ti, thiab lwm yam khoom. . Austenitic stainless hlau yog tsis-sib nqus thiab muaj siab toughness thiab plasticity, tab sis nws lub zog yog tsawg. Nws yog tsis yooj yim sua kom ntxiv dag zog rau nws los ntawm theem transformation. Nws tsuas tuaj yeem ntxiv dag zog los ntawm kev ua haujlwm txias. Yog tias S, Ca, Se, Te, thiab lwm yam ntxiv, nws muaj kev ua haujlwm zoo.
Stainless hlau tuaj yeem muab faib raws li microstructure tom qab kev kho cua sov:
1. Ferritic stainless hlau
Ferritic stainless hlau (400 series) muaj 15 feem pua rau 30 feem pua chromium thiab 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. Cov 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. Tus nqi ntawm ferritic stainless hlau tsis yog tsuas yog qis thiab ruaj khov tab sis kuj muaj ntau yam tshwj xeeb thiab qhov zoo. Nws tau raug pov thawj tias ferritic stainless hlau yog ib qho khoom siv zoo tshaj plaws hauv ntau daim ntawv thov teb uas tau xav tias tsuas yog austenitic stainless hlau (300 series).
2. Martensitic stainless hlau
Stainless 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 zoo yog Cr13 hom, xws li 2Cr13, 3Cr13, 4Cr13, thiab lwm yam. Tom qab quenching, hardness yog siab dua, thiab sib txawv tempering kub muaj sib txawv ua ke ntawm lub zog thiab toughness. Nws yog tsuas yog siv rau chav turbine hniav, tableware, thiab cov cuab yeej phais. Raws li qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg, martensitic stainless hlau tuaj yeem muab faib ua ob hom: martensitic chromium steel thiab martensitic chromium-nickel steel. Raws li cov qauv thiab kev siv zog, nws tuaj yeem muab faib ua martensitic stainless hlau, martensitic thiab semi-austenitic (los yog semi-martensitic) nag lossis daus-hardening stainless hlau, thiab maraging stainless hlau.
3. Austenitic stainless hlau
Austenitic stainless hlau hais txog stainless hlau nrog cov qauv austenitic ntawm chav tsev kub. Thaum cov hlau muaj li ntawm 18 feem pua Cr, 8 feem pua ~ 25 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 nto moo 18Cr-8Ni steel thiab siab Cr-Ni series steel tsim los ntawm kev nce Cr thiab Ni cov ntsiab lus thiab ntxiv Mo, Cu, Si, Nb, Ti, thiab lwm yam khoom. . Austenitic stainless hlau yog tsis-sib nqus thiab muaj siab toughness thiab plasticity, tab sis nws lub zog yog tsawg. Nws yog tsis yooj yim sua kom ntxiv dag zog rau nws los ntawm theem transformation. Nws tsuas tuaj yeem ntxiv dag zog los ntawm kev ua haujlwm txias. Yog tias S, Ca, Se, Te, thiab lwm yam ntxiv, nws muaj kev ua haujlwm zoo.
4. Cov dej nag-hardened stainless hlau
Precipitation hardening stainless hlau yog hais txog ib hom high-strength stainless hlau uas ntxiv ntau hom thiab ntau ntawm ntxiv dag zog rau cov tshuaj muaj pes tsawg leeg ntawm stainless hlau thiab precipitates ntau hom thiab ntau ntawm carbides, nitrides, carbonitrides thiab intermetallic tebchaw los ntawm cov nag lossis daus hardening txheej txheem. , uas tsis tsuas yog txhim kho lub zog ntawm cov hlau, tab sis kuj tswj kom txaus toughness. Nws yog hu ua PH hlau luv luv. Precipitation-hardening stainless hlau tuaj yeem muab faib ua peb hom raws li cov qauv metallographic ntawm matrix: martensitic, semi-austenitic, thiab austenitic.
