Tso lus
1.4436 stainless hlau, feem ntau hu ua 316 lossis UNS S31600, yog tus qauv molybdenum- alloyed austenitic stainless hlau. Qhov sib ntxiv ntawm molybdenum ho txhim kho nws cov kev tiv thaiv corrosion, tshwj xeeb tshaj yog tiv thaiv chlorides thiab cov khoom siv tshuaj, ua rau nws muaj ntau yam khoom siv rau cov ntawv thov kev ua haujlwm zoo dua corrosion piv rau 304. Nws yog dav siv nyob rau hauv marine ib puag ncig, tshuaj ua lag luam, khoom siv tshuaj, thiab kev lag luam khoom noj.
Qhov no molybdenum- qib kev txhim kho yog tus qauv thoob plaws txhua lub tshuab loj thoob ntiaj teb.

Cov yam ntxwv tseem ceeb thiab kev siv ntawm 1.4436 / 316
Superior Corrosion Resistance:Cov ntsiab lus molybdenum muab kev tiv thaiv zoo dua rau pitting thiab crevice corrosion hauv chloride-muaj ib puag ncig piv rau 304.
Zoo Acid Resistance:Muab kev txhim kho kev tiv thaiv rau ntau cov kua qaub, suav nrog sulfuric, phosphoric, thiab acetic acids, ua rau nws tsim nyog rau kev siv tshuaj lom neeg.
Zoo heev Formability thiab Weldability:Tuav cov txheej txheem zoo thiab vuam cov yam ntxwv ntawm austenitic stainless hlau, txawm hais tias kev ruaj khov yuav raug txiav txim siab rau qhov hnyav welded seem.
Cov ntawv thov tseem ceeb:
Marine & Coastal:Nkoj fittings, underwater Cheebtsam, thiab architectural cladding nyob rau hauv ntsev -laden atmospheres.
Kev ua tshuaj lom neeg:Tank, kav dej, li qub, thiab twj tso kua mis los tuav cov tshuaj corrosive.
Pharmaceutical & Khoom noj khoom haus:Cov cuab yeej xav tau kev huv siab thiab ua haujlwm rau cov neeg ua kom tsis muaj menyuam.
Cov cuab yeej kho mob:Cov cuab yeej phais thiab cov khoom cog hauv cov xwm txheej tshwj xeeb.
Architectural:High -kawg lub tsev facades thiab cov khoom siv nyob rau hauv corrosive ib puag ncig.
Dab tsi yog qhov zoo ntawm 316 (1.4436) tshaj 304 (1.4301) stainless hlau?
Qhov txiaj ntsig tseem ceeb yog qhov sib ntxiv ntawm 2-2.5% molybdenum, uas ua rau muaj kev txhim kho zoo heev rau qhov chaw corrosion, tshwj xeeb tshaj yog pitting thiab crevice corrosion, nyob rau hauv chloride- muaj ib puag ncig. Qhov no ua rau 316 qhov kev xaiv zoo tshaj plaws rau cov ntawv thov nyob rau hauv ib puag ncig marine, chemical processing nroj tsuag tuav cov tshuaj chlorides, thiab nyob qhov twg yuav raug rau ntsev, brine, los yog halogen compounds. Thaum 304 yog qhov tsim nyog rau kev siv lub hom phiaj dav dav, 316 muab kev pabcuam txuas ntxiv rau hauv cov xwm txheej hnyav dua.
316 piv rau 316L thiab 316Ti li cas?
316 (1.4436) yog tus qauv qib nrog carbon mus txog 0.07%. 316L (1.4404) yog qhov qis-carbon variant nrog siab tshaj 0.03% carbon, muab kev tiv thaiv zoo rau kev hnov mob thaum vuam thiab nyiam rau qhov hnyav welded seem {{7}5}Ti (1. titanium-stabilized version, muab cov txiaj ntsig zoo sib xws rau 316L tab sis nrog titanium ntxiv rau stabilization. Qhov kev xaiv nyob ntawm daim ntawv thov: 316 yog tsim rau kev siv dav dav, 316L rau cov qauv welded, thiab 316Ti rau cov ntawv thov uas yuav tsum tau muaj kev ruaj khov thiab siab - kev pabcuam kub.
