Stainless steel yeeb nkab fittings yog dav siv nyob rau hauv ntau industries, yog li dab tsi yog cov khoom ntawm stainless hlau yeeb fittings?
1. Qhov loj feem ntawm silicon hauv cam khwb cia hlau yog 0.2% -0.45%. Cov ntsiab lus no muaj me ntsis cuam tshuam rau cov khoom siv kho tshuab. Silicon yuav tsum muaj qee cov ntsiab lus los xyuas kom meej lub deoxidation ntawm hlau. Yog li ntawd, silicon yog ib qho txiaj ntsig zoo hauv cov hlau.
2. Kev ua haujlwm ntawm carbon steel feem ntau yog nyob ntawm cov ntsiab lus carbon. Raws li cov ntsiab lus carbon hauv steel nce, lub zog thiab hardness ntawm steel nce, thiab cov yas thiab toughness txo.
3. Sulfur yog ib qho teeb meem hauv cov hlau thiab feem ntau muaj nyob rau hauv daim ntawv hlau. Nws tsim ib qho eutectic nrog hlau thiab muaj qhov melting point ntawm 989 degrees, uas yog qis dua lub melting point ntawm stainless hlau. Thaum lub sij hawm solidification txheej txheem ntawm hlau, sulfides feem ntau precipitate ntawm grain ciam teb ntawm cov hlau. Vim lub zog qis thiab brittleness ntawm cov hlau, cov khoom siv ntawm cov hlau yog zoo heev
Txo thiab ua rau thermal brittleness ntawm qhov kub thiab txias. Yog hais tias cov hlau molten tsis deoxidized thiab muaj ntau FEC, cov sulfide yuav tsim ib tug ternary eutectic nrog hlau thiab Fe, nrog ib tug qis melting point (kwv yees li 940 degrees) thiab muaj kev puas tsuaj ntau dua. Sulfur kuj muaj kev cuam tshuam tsis zoo rau cov weldability ntawm steel. Yog li ntawd, sulfur yuav tsum tau muab tshem tawm kom ntau li ntau tau thaum lub sij hawm steelmaking txheej txheem
4. Phosphorus kuj yog ib qho teeb meem impurity hauv hlau. Zoo heev txhais tau tias qhov me dua qhov zoo, qhov loj feem yuav tsum tsawg dua 0.06%.
5. Cov feem ntau ntawm manganese nyob rau hauv cam khwb cia steel yeeb nkab fittings yog 0.5% rau 0.8%, thiab nws muaj nuj nqi yog deoxidation thiab desulfurization.
GNEE Steel Group yog Tuam Tshoj tus kws tshaj lij ib-nres muab cov saw hlau lag luam rau cov khoom siv hlau. Nws cov yeeb nkab stainless hlau ntau lawm tshuab tau mus txog lub ntiaj teb cov txheej txheem nruab nrab. Nws tau raug lees paub los ntawm ntau lub tuam txhab ua haujlwm thiab tau dhau los ua lub hnub qub lag luam hauv Asia.
