Umgangatho weSizwe waseTshayina we-GB/T 222-2025: "Intsimbi kunye ne-Alloys - Ukuphambuka okuvumelekileyo kwi-Chemical Composition of Finished Products" iya kusebenza ngomhla we-1 kaDisemba, i-2025.

I-GB/T 222-2025 "I-Steel kunye ne-Alloys - Ukuphambuka okuvumelekileyo kwi-Chemical Composition of Finished Products" iya kuqala ukusebenza ngoDisemba 1, 2025, ithathe indawo yemigangatho yangaphambili ye-GB / T 222-2006 kunye ne-GB / T 25829-2010.

Umxholo ongundoqo woMgangatho
1. Umda: Ugubungela ukutenxa okuvumelekileyo kwimichiza yeemveliso ezigqityiweyo (kubandakanywa neebhilidi) zentsimbi engekho i-alloy, i-low-alloy steel, i-alloy steel,yenziwe ngentsimbi eshayinayo, intsimbi ekwaziyo ukumelana nobushushu, i-alloys enganyangekiyo kwi-corrosion, kunye ne-alloys enobushushu obuphezulu.

 
2. IiNguquko eziNxibeleleyo kwezobuGcisa:
Ulwahlulo olongezelelweyo lokuphambuka kwesulfure okuvumelekileyo kwintsimbi engekho i-alloy kunye nentsimbi ephantsi.
Ulwahlulo olongezelelweyo lokutenxa okuvumelekileyo kwisulfure, i-aluminiyam, initrogen, kunye nekhalsiyam kwiintsimbi zealloy.
Ukongezwa kokutenxa okuvumelekileyo kokwakheka kweekhemikhali kwi-alloys enganyangekiyo kwi-corrosion kunye ne-alloys yobushushu obuphezulu.

3. Ukuphunyezwa kweShedyuli
Umhla wokupapashwa: Agasti 29, 2025
Umhla wokuphunyezwa: 1 Disemba 2025
