A302 GR.D Kohua me te Peehanga Waka Pereti maitai

Pereti rino Kohua A302 Koeke D he momo rino koranu me te konupora, Molybdenum me te nickel. Kei roto i te A302 Grade D tetahi huānga Nickel teitei ake i roto i te okeoke atu i te Pereti maitai Kohua A302 Koeke C.Pressure ipu maitai pereti no ratou te awhe uara i roto i nga taonga miihini rite A302 Koeke B me te A302 Koeke C, ka tuku te kaha ki runga ake i te 345 Mpa, me te kaha tensile i roto i te 550-690 Mpa.Gnee maitai e hiahia ana ki te tuku MTC i raro i te whakatakotoranga EN 10204 3.1, EN 10204 3.2 ranei me nga tirohanga tuatoru.
