Chitsulo Chosapanga Dzimbiri 309 Chopanda Msoko
Kufotokozera Kwachidule:
Chitsulo Chosapanga Dziwe 309 ndi chitsulo chosapanga dzimbiri cha austenitic chomwe chimateteza kutentha chomwe chili ndi chromium yambiri ndi nickel.
Kuyesa kwa Hydrostatic Pipe Yopanda Chitsulo:
Chitsulo Chosapanga Dzimbiri 309 chimadziwika ndi kukana kutentha kwambiri, zomwe zimapangitsa kuti chigwiritsidwe ntchito komwe kutentha kwambiri kumakhala kofala. Chitsulochi chimapereka kukana bwino dzimbiri, makamaka m'malo omwe kutentha kumakhala kochepa. Kuchuluka kwa chromium ndi nickel kumathandizira kuti chitsulocho chisagwire dzimbiri komanso mphamvu ya kutentha kwambiri. Mawu akuti "opanda msoko" amatanthauza kuti chubucho chimapangidwa popanda misoko yolumikizidwa. Machubu opanda msoko nthawi zambiri amakondedwa m'mapulogalamu amphamvu komanso otentha kwambiri chifukwa cha kapangidwe kawo kofanana. Machubu Opanda Msoko 309 a Chitsulo Chosapanga Dzimbiri amapeza ntchito m'mafakitale osiyanasiyana, kuphatikizapo ndege, kukonza mankhwala, kukonza kutentha, ndi zina zambiri, komwe kutentha kwakukulu ndi malo owononga kumakumana.

Ma phukusi a SAKY STEEL:
1. Kulongedza katundu ndikofunikira kwambiri makamaka pankhani yotumiza katundu kunja kwa dziko komwe katundu amadutsa m'njira zosiyanasiyana kuti akafike komwe akupita, choncho timaika chidwi chathu chachikulu pa kulongedza katundu.
2. Saky Steel amanyamula katundu wathu m'njira zosiyanasiyana kutengera zinthuzo. Timanyamula katundu wathu m'njira zosiyanasiyana, monga,
