Chitsulo cha AISI D2 1.2379 Chida
Kufotokozera Kwachidule:
D2 ndi chitsulo cha chitsulo chokhala ndi kaboni wambiri, chomwe chimadziwika ndi kukana kwake kuwonongeka komanso kulimba kwake. Nthawi zambiri chimagwiritsidwa ntchito popanga zinthu monga blanking dies, kupanga dies, ndi zida zodulira.
Chitsulo cha Chida cha 1.2379:
Chitsulo cha D2, chomwe chimapezeka mu mipiringidzo yozungulira ndi mbale, ndi chabwino kwambiri popanga zinyalala zogwirira ntchito zozizira zokhala ndi magawo akuluakulu, mawonekedwe ovuta, komanso zofunikira kwambiri kuti zisamawonongeke komanso zisawonongeke. Chimadziwikanso kuti DIN 1.2379 ndi JIS SKD11 chitsulo, chimagwera m'gulu la zinyalala zogwirira ntchito zozizira zokhala ndi kaboni yambiri, zokhala ndi chromium yambiri. Chitsulochi chimagwiritsidwa ntchito kwambiri padziko lonse lapansi chifukwa cha kulimba kwake kwapadera komanso kukana kwambiri kutentha kwambiri. Pambuyo pozimitsa ndi kupukuta, chitsulo cha D2 chimakhala ndi mphamvu zabwino kwambiri zotsutsana ndi dzimbiri, ndipo kusintha kochepa kumachitika panthawi yokonza kutentha.

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,
