Stainless hlau
Thaum cov pa roj carbon hlau yooj yim alloyed nrog qhov tsawg kawg nkaus ntawm 10.5% Chromium (Cr) los txhim kho corrosion kuj, cov khoom tshwm sim yog stainless hlau. Nws kuj tseem yuav muaj lwm cov ntsiab lus xws li Nickel (Ni), Molybdenum (Mo), Titanium (Ti), thiab Nitrogen (N) txhawm rau txhim kho cov khoom xws li toughness, lub zog, kub tsis kam, durability thiab weldability.
Stainless hlau yog categorized raws li nws metallurgical qauv rau hauv austenitic stainless hlau, ferritic stainless hlau, martensitic stainless hlau, duplex stainless hlau, thiab nag lossis daus hardened stainless hlau. Txhua tus qauv nthuav tawm ib ntug ntawm lwm tus. Piv txwv li, cov qauv austenitic muaj qhov zoo tshaj plaws corrosion kuj thiab formability, tab sis ferritic muaj kev tiv thaiv zoo dua rau feem ntau kev ntxhov siab corrosion cracking (SCC) thiab yog tus nqi ntau dua, ces cov qauv duplex muab lub zog siab thiab kev ntxhov siab corrosion cracking kuj los ntawm kev sib txuas cov qauv ntawm ob lub qub, cov qauv martensitic tuaj yeem raug kho kom sov kom ua tiav lub zog siab dua thiab ua kom tawv tawv ntawm cov hlau tsis muaj zog, thiab preci. thiab martensitic los ntawm nag lossis daus hardening. Qhov no versatility ua rau stainless hlau tseem ceeb nyob rau hauv kev lag luam uas durability thiab corrosion kuj tseem ceeb heev.
Cov pa roj carbon (C) nce hardness tab sis tuaj yeem txo qhov kev tiv thaiv corrosion thaum siv ntau dua. Chromium (Cr) tsim ib txheej oxide passive rau ntawm qhov chaw, muab kev tiv thaiv corrosion. Nickel (Ni) stabilizes cov qauv austenitic, txhim kho toughness. Molybdenum (Mo) txhim khu kev tiv thaiv rau crevice corrosion, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig chloride. Nitrogen (N) boosts lub zog thiab stabilizes austenitic theem.
Cov qib tshwj xeeb thiab cov qib sib npaug thoob ntiaj teb peb siv tau teev tseg hauv qab no. Thov nco ntsoov tias cov tseem ceeb tshuaj muaj pes tsawg leeg tau teev tseg raws li GB / T steel designations. Rau cov hlau tsis muaj steel, peb tsuas yog muab ze rau -net- zoo li cov peev txheej castings thiab MIM rau cov khoom siv siab- precision, nrog cov txheej txheem kev kho cua sov tom qab (kev daws teeb meem / kev daws teeb meem annealing + aging) thiab CNC machining kom ua tiav qhov yuav tsum tau muaj corrosion thiab mechanical zog rau ntau yam kev siv.
