440c Chitsulo Chosapanga Dzira Chosapanga Dzira
Kufotokozera Kwachidule:
UNS S44000 Flat Bars, SS 440 Flat Bars, Wogulitsa, Wopanga ndi Wotumiza Zinthu ku China.
Zitsulo zosapanga dzimbiri ndi zitsulo zokhala ndi aloyi ambiri zomwe zimakhala ndi kukana dzimbiri kwambiri poyerekeza ndi zitsulo zina chifukwa cha kukhalapo kwa chromium yambiri. Kutengera kapangidwe kake ka kristalo, zimagawidwa m'mitundu itatu monga zitsulo za ferritic, austenitic, ndi martensitic. Gulu lina la zitsulo zosapanga dzimbiri ndi zitsulo zolimba ndi mvula. Ndi kuphatikiza kwa zitsulo za martensitic ndi austenitic. Chitsulo chosapanga dzimbiri cha Giredi 440C ndi chitsulo chosapanga dzimbiri cha giredi 440C. Chili ndi mphamvu zambiri, kukana dzimbiri pang'ono, komanso kuuma bwino komanso kukana kuvala. Giredi 440C imatha kupeza, pambuyo pa kutentha, mphamvu yayikulu kwambiri, kuuma ndi kukana kuvala kwa zitsulo zonse zosapanga dzimbiri. Kuchuluka kwa kaboni komwe kali nako ndiko komwe kumayambitsa makhalidwe awa, zomwe zimapangitsa 440C kukhala yoyenera kwambiri ntchito monga mipira ndi zigawo za valve.

| 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,
Mapulogalamu:
Kugwiritsa ntchito komwe kumafuna kukana dzimbiri pang'ono komanso mphamvu zambiri zamakanika ndikwabwino kwambiri pa Alloy 440. Zitsanzo za kugwiritsa ntchito komwe kumagwiritsa ntchito Alloy 440 nthawi zambiri ndi izi:
- Ma bereji a zinthu zozungulira
- Mipando ya mavavu
- Masamba a mpeni apamwamba kwambiri
- Zida zopangira opaleshoni
- Ma Chisel
