Duplex steel hais txog tsev neeg ntawm stainless cov hlau uas muaj ob-theem-nruab nrab Crystal crystal crystal crystal crystal crystal crystal) ntu. Qhov qauv no tau ua tiav ob theem yog ua tiav los ntawm kev sib xyaw tshwj xeeb uas suav nrog cov khoom chromium, npib tsib xee, molybdenum, thiab nitrogen.
Cov hlau dulex uas nquag muaj tshaj plaws rau cov neeg tsis muaj S3XXX, qhov twg "sawv ntsug rau kev sib tw tsis muaj pes tsawg, thiab cov lej qhia meej meej tagnrho cov muaj pes tsawg leeg. Qhov ob-theem microstructure imparts muaj kev sib txuam ntawm cov khoom siv uas xav tau, ua rau cov roj av dulex haum rau ntau yam kev siv. Qee cov ntsiab lus tseem ceeb ntawm cov hlau duplex suav nrog:
1.Corrosion Restance: steel hlau muaj zoo heev corrosion tsis kam, tshwj xeeb hauv qhov chaw hnyav muaj cov chlorides. Qhov no ua rau nws haum rau kev siv tshuaj lom neeg siv tshuaj, roj thiab roj av, thiab cov ntawv thov marrine.
2.High lub zog: piv rau ustenitic stainless hlau, tus hlau ob lub zog muaj zog, ua rau nws haum rau qhov chaw uas yuav tsum muaj zog dua.
3.Cov tawv thiab ductility: Chav yas ua kom zoo ua kom zoo thiab kev du ncauj, txawm tias tsis tshua muaj cua txias. Qhov kev sib xyaw no ntawm cov khoom yog qhov tseem ceeb hauv cov ntawv thov uas cov khoom siv yuav raug rau sib txawv ntawm cov thauj khoom thiab ntsuas kub.
4.Thov ua kom xeb tawm tsam: Chav ua kom pom kev ua kom ntxhov siab, ib hom corrosion uas tuaj yeem tshwm sim nyob rau hauv kev sib xyaw ua ke ntawm lub tensile kev ntxhov siab thiab ib puag ncig muaj xeb.
5.Com-zoo: Thaum lub taub hau yas yuav kim dua li cov pa roj tsis tshua muaj nqi, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas yog lub zog yog qhov tseem ceeb.
Koom haum RuleX stainless hlau muaj pes tsawgDuplex 2205 (uns unst s32205)Thiab Duplex 2507 (uns unic s32750). Cov kawm qib no tau siv dav hauv kev lag luam xws li kev ua yeeb yam, roj thiab roj kev tshawb nrhiav, tawm thiab cov pulp thiab cov ntawv tsim khoom.
