Muaj ntau hom stainless hlau. Ntawm no kuv yuav qhia koj txog kev faib cov hlau siv hauv stainless hlau yeeb nkab lub luj tshib thiab tees. Cov ntsiab lus yog raws li nram no:
1. Austenitic stainless hlau: Lub matrix feem ntau yog austenite qauv (theem) nrog lub ntsej muag-centered cubic qauv, uas tsis yog-magnetic, thiab feem ntau yog txias-ua hauj lwm (thiab tej zaum yuav ua rau magnetism) stainless hlau;
2. Austenite-ferrite (duplex) stainless hlau: Lub matrix muaj ob qho tib si austenite thiab ferrite theem (cov ntsiab lus ntawm cov theem qis yog feem ntau ntau dua 15%), yog hlau nplaum, thiab tuaj yeem Stainless hlau uas tuaj yeem ua kom tawv nqaij ua haujlwm txias;
3. Ferritic stainless hlau: Cov matrix feem ntau yog ferrite (theem) nrog lub cev-centered cubic crystal qauv, uas yog sib nqus thiab tsis tuaj yeem hardened los ntawm kev kho cua sov, tab sis kev ua haujlwm txias tuaj yeem ua rau nws zoo stainless hlau;
4. Martensitic stainless hlau: Lub matrix yog martensitic, uas yog sib nqus thiab tuaj yeem kho nws cov khoom siv los ntawm kev kho cua sov;
5. Precipitation hardening stainless hlau: Lub matrix yog austenite los yog martensitic, thiab tuaj yeem hardened (strengthened) los ntawm nag lossis daus hardening (tseem hu ua aging hardening).
Stainless hlau tee Los ntawm nws lub npe, peb tuaj yeem pom tias cov khoom siv ntawm lub luj tshib stainless hlau yuav tsum yog stainless hlau. Qhov sib txawv tseem ceeb ntawm stainless hlau luj tshib thiab carbon steel luj tshib yog cov khoom siv. Cov tshuaj muaj pes tsawg leeg uas nws muaj yuav ua rau lub luj tshib ntawm lub luj tshib los ntawm xeb thiab corroding rau lub sij hawm ntev. Lub luj tshib stainless hlau muaj ib txoj kab me me ntawm ob qho kawg ntawm txoj kab ncaj nraim thiab ntsug bifurcation kawg, uas yog siv rau kev sib txuas ntawm cov ceg me me. Lub luj tshib tau muab faib ua stainless hlau luj tshib, forged steel luj tshib, carbon steel, alloy steel, thiab lwm yam raws li lawv cov ntaub ntawv. Lub luj tshib fittings tuaj yeem muab faib ua square npoo thiab puag ncig.
