Qhov loj me: Od 12.7 - 1422 hli, wt 1 - 45 hli, ntev:5 - 12 m
Hom: Seamless thiab Welded.
S44660 yog lub luag haujlwm super ferritic stainless hlau uas muab kev zam tshwj xeeb chloride thiab acid tiv taus ntawm ib feem ntawm cov hlau steel hlau. Nrog 30% chromium thiab 4% molybdenum, qhov no unserritic steel hlau seperforms 31-10 xyoo nyob rau hauv ib puag ncig ib puag ncig zoo li dej hiav txwv thiab tshuaj lom neeg.
Cov Ntsiab Lus Tseem Ceeb:
✔ Xoom Nickel{{0- Tshem tawm cov kev ntxhov siab ntawm kev ua txhaum kev phom sij
✔ Kev tsim tsa{{0- qhov zoo tagnrho rau high-} lub tshuab siab
✔ Nqi -}}}}{{0- 50}} siv dua li Super Duplex lwm txoj
✔ Yooj Yim Fabrication Yooj Yim- zoo heev weldability thiab machinability
Pro tswv yim:Thaum 316L tsis ua tiav tab sis duplex yog overkill - s44660 yog qhov sib npaug zoo meej!
