Chain Parameter
SCIC Grade 70 (G70) maunyolo onyamula katundu amapangidwa molingana ndi miyezo ya NACM. Maulalo amaketani amapangidwa bwino / kuyang'aniridwa kuwotcherera & machiritso a kutentha amawonetsetsa kuti maunyolo amakanika kuphatikiza mphamvu yopukutira, mphamvu yotsimikizira, kuswa mphamvu, elongation & kuuma. Kuyang'ana kwathunthu ndi kuyezetsa kumayikidwa pa chain batch.
Unyolo wa G70 Transport uli ndi zabwino zake zaukhondo, zopepuka, zamphamvu komanso zodalirika, motero ndizoyenera kugwiritsa ntchito zomangira zonyamula katundu ndi mafakitale onyamula ndi kutumiza.
Titha kupereka maunyolo ndi ndowe zogwirira ndi zinthu zina, malinga ndi utali wamakasitomala.
