GB/T5310-2008Ityhubhu yentsimbi engenamthungo luhlobo lwetyhubhu yentsimbi ekumgangatho ophezulu. Ityhubhu yebhoyila yahlulwe yaba yityhubhu yebhoyila eqhelekileyo kunye netyhubhu yebhoyila enoxinzelelo oluphezulu ngokwendlela esebenza ngayo kubushushu obuphezulu. Ityhubhu yebhoyila enoxinzelelo oluphezulu isetyenziselwa kakhulu ukuvelisa iibhoyila zomphunga ezinoxinzelelo oluphezulu kunye nezo zingaphezulu koxinzelelo oluphezulu, iipayipi kunye nezinye intsimbi yesakhiwo sekhabhoni ekumgangatho ophezulu, intsimbi yesakhiwo se-alloy kunye nentsimbi engenamthungo enganyangekiyo enganyangekiyo. [1] Ezi tyhubhu zebhoyila zisebenza kubushushu obuphezulu kunye noxinzelelo, zivelisa igesi yeflue enobushushu obuphezulu kunye nomphunga wamanzi, ezinokuthi zichaphazeleke yi-oxidation kunye nokugqwala.

Inqanaba lentsimbi

(1) Intsimbi yesinyithi yekhabhoni esemgangathweni ophezulu 20G, 20MnG, 25MnG. 

(2) Isakhiwo se-alloy intsimbi 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, njl.njl. 

(3) Intsimbi ekwaziyo ukumelana nobushushu obugqithisileyo esetyenziswa rhoqo yi-1Cr18Ni9, ityhubhu yebhoyila eyi-1Cr18Ni11Nb ukongeza ekuqinisekiseni ukwakheka kweekhemikhali kunye neempawu zoomatshini, ukwenza uvavanyo loxinzelelo lwamanzi, ukwenza uvavanyo lokutsha, kunye noxinzelelo. Iityhubhu zentsimbi zihanjiswa zikwimeko yonyango lobushushu. 

Ukongeza, kufuneka ulwakhiwo oluncinci, ubungakanani bengqolowa kunye nomgangatho wokususa iikhabhoni kwiityhubhu zentsimbi ezigqityiweyo.

Ukongeza kwityhubhu yentsimbi engenamthungo yebhoyila yoxinzelelo oluphezuluGB/T5310-2008ezikhankanyiweyo apha ngasentla, iimveliso eziphambili zenkampani yethu zezi:
