Mpiringidzo wa Chitsulo Chosapanga Dzimbiri wa ASTM A638 660
Kufotokozera Kwachidule:
660A ikutanthauza mkhalidwe weniweni wa A286 alloy (UNS S66286), yomwe ndi chitsulo chosapanga dzimbiri champhamvu kwambiri, kutentha kwambiri, komanso chosagwira dzimbiri.
660A Chitsulo Chosapanga Dzimbiri:
ASTM A453 Giredi 660 ndi chitsulo chosapanga dzimbiri cholimba chomwe chimagwiritsidwa ntchito kwambiri pomangirira ndi kuyika zinthu zomangira kutentha kwambiri. Chitsulo chosapanga dzimbiri cha A286 cha 660A chimayikidwa mu yankho, zomwe zimapangitsa kuti chikhale cholimba, cholimba bwino, komanso cholimba kwambiri. Izi zimapangitsa kuti chigwiritsidwe ntchito molimbika m'magawo a ndege, magalimoto, ndi mafakitale komwe zipangizo ziyenera kugwira ntchito modalirika pansi pa mikhalidwe yovuta komanso yotentha kwambiri. Chimalimbana bwino ndi okosijeni ndi dzimbiri m'malo otentha kwambiri. Chimalimbana bwino ndi mikhalidwe yosiyanasiyana yowononga, kuphatikizapo madzi a m'nyanja, ma acid ofatsa, ndi alkali.

Kugwiritsa ntchito mipiringidzo ya Giredi 660 mu Kalasi A/B/C/D:
ASTM A453/A453M imafotokoza za ma bolting otentha kwambiri okhala ndi ma coefficients okulitsa ofanana ndi chitsulo chosapanga dzimbiri cha austenitic. Chimodzi mwa ma grade omwe amagwiritsidwa ntchito kwambiri ndi ma bolti a Giredi 660. Timapanga ma stud bolting,mabotolo a hex, mabotolo okulitsa,ndodo zolumikizidwa, ndi zina zambiri malinga ndi A453 Giredi 660 mu Makalasi A, B, C, ndi D, omwe cholinga chake ndi ntchito zapadera zauinjiniya.
Chifukwa Chiyani Sankhani Ife?
•Mukhoza kupeza zinthu zabwino kwambiri malinga ndi zomwe mukufuna pamtengo wotsika kwambiri.
•Timaperekanso mitengo yotumizira katundu (Reworks, FOB, CFR, CIF, ndi yotsika mtengo). Tikukulimbikitsani kuti mugule katundu woti mutumize katunduyo, zomwe zingakuthandizeni kukhala ndi ndalama zochepa.
•Zipangizo zomwe timapereka ndi zotsimikizika kwathunthu, kuyambira pa satifiketi yoyesera zinthu zopangira mpaka chiganizo chomaliza. (Malipoti adzawonetsedwa pakufunika)
•Tikutsimikizira kuti tipereka yankho mkati mwa maola 24 (nthawi zambiri mu ola lomwelo)
•Perekani lipoti la SGS TUV.
•Tadzipereka kwathunthu kwa makasitomala athu. Ngati sizingatheke kukwaniritsa zofunikira zanu mutafufuza njira zonse, sitidzakusokeretsani polonjeza zinthu zabodza zomwe zingapangitse ubale wabwino ndi makasitomala.
•Perekani chithandizo chokhazikika.
Kulongedza:
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,
