Dab tsi yog 2507 stainless hlau?
Tso lus
2507 stainless hlau nyob rau txoj haujlwm tseem ceeb hauv kev ua lag luam thoob ntiaj teb, tshwj xeeb tshaj yog hauv cov roj av engineering, roj thiab fais fab kev lag luam. Vim tias tus nqi loj tus nqi hloov ntawm cov tseem ceeb ntawm cov ntsiab xws li chromium, npib tsib xee thiab molybdenum, tus nqi ntawm 2507 stainless hlau kuj tseem yuav cuam tshuam los ntawm cov yam ntxwv. Nyob rau hauv xyoo tsis ntev los no, nrog rau kev nce kev lag luam kev thov rau kev ua haujlwm siab stainless hlau, tus nqi ntawm dupless steel hlau tau qhia ib yam upward qauv.
Kab lus no yuav qhia tau raws li kev nthuav dav ntawm lub cev thiab tshuaj tsis zoo, ua cov khoom siv thiab kev ceev faj ntawm cov hlau 2507, thiab muab cov ntaub ntawv cov ntaub ntawv tsim nyog.
Tus qauv duplex ntawm 2507 stainless hlau muaj txog li 50% thiab 50% ferrite, uas ua rau muaj lub zog siab thaum muaj kev cuam tshuam corrosion.

Zauv khoom ntawm 2507 stainless hlau
Kev Kho Cua Sov Cov Khoom Cua
Kev kho cua sov ntawm 2507 stainless hlau yuav tsum tau nqa tawm ntawm {{1} degree kom tsis txhob muaj kev kub ntxhov ntawm {2}} degree. Tom qab kev kho cua sov, zam kom tsis txhob nyob ntawm qhov kub ntev ntev kom ntseeg tau tias cov khoom siv tshuab zoo tshaj plaws thiab corrosion tsis kam.
Kev sib sau ua tau zoo
2507 stainless hlau muaj kev ua tau zoo txias, tab sis vim nws lub zog siab dua, muaj zog dua thaum lub sijhawm ua tiav. Cov kev sib sau kub yuav tsum tau nqa tawm ntawm 950-1100 degree, thiab zam kev nyob hauv thaj tsam ntawm {2} degree los tiv thaiv kev tsim ntawm σ theem.
Vuam Performance
2507 Stainless hlau muaj kev ua haujlwm zoo vuam, thiab cov qauv vuam muaj xws li Tig lub sij hawm siv hluav taws xob, Mig vuam, Mig vuam, Mig vuam, laser vuam ib tiam thiab xyuas kom cov vuam ib qho kev tswj hwm kom haum.
