Ngomhla zingama-31 kuZibandlela, 2021, i-ultra-low-low steel plate 9Ni steel plate ye-LNG (igesi yemvelo ewuketshezi) ekhiqizwe i-Hyundai Steel yaphumelela ekuhlolweni kwesitifiketi se-KOGAS (Korea Natural Gas Corporation).Ubukhulu bepuleti yensimbi ye-9Ni buyi-6 mm kuya ku-45 mm, futhi ububanzi obukhulu bungamamitha angu-4.5, okuyiwona obanzi kakhulu emhlabeni.Ukugunyazwa kwalesi sitifiketi kuthuthukisa futhi ukuncintisana kwemakethe ye-Hyundai Steel eNingizimu Korea.
Kubikwa ukuthi ukuze kuphumelele lesi sitifiketi, iHyundai Steel kanye nomkhiqizi wezinto zokushisela iHyundai General Metals Co., Ltd. baye baqaphela ukwenziwa kwendawo kwazo zonke izinto zokushisela.KwaHyundai Steel bathe ukwenziwa kwasendaweni kwezinto zokushisela kungonga cishe u-30% wezindleko uma kuqhathaniswa nokusetshenziswa kwezinto ezivela kwamanye amazwe.
I-9Ni steel thick plate iwumkhiqizo wepuleti eliwugqinsi osebenza kakhulu osetshenziselwa ukuqinisekisa ukuphepha kwamathangi okugcina e-LNG asolwandle nasemhlabeni.Izici zayo eziyinhloko okuqukethwe kwe-nickel ephezulu kanye nokuhlanzeka okuphezulu.Ukugcina amandla aphezulu kanye nokuqina komthelela okuhle kakhulu, kungenye yezinto eziphambili ezisetshenziselwa ukwakha amathangi amakhulu okugcina e-LNG.
