GB5310ni code isanzwe yubushinwa bwigihugu "Imiyoboro idafite ibyumaAmashanyarazi menshi".

20G: 20G nimwe mu byiciro bikoreshwa cyane muri GB5310, hamwe nibice nyamukuru bya karubone, manganese na silicon.Ifite ibikoresho byiza byubukanishi hamwe nogusudira, kandi ikoreshwa cyane mugukora ibice byingenzi nkurukuta rwakonje rwamazi, superheater, abashinzwe ubukungu ningoma mumashanyarazi.

15CrMoG: Iki cyuma kirimo chromium na molybdenum, kandi gifite imbaraga zo hejuru yubushyuhe bwo hejuru no kurwanya okiside.15CrMoG imiyoboro idafite ibyuma ikoreshwa kenshi mugukora ubushyuhe bwo hejuru hamwe numuvuduko ukabije wumuyaga, imitwe numuyoboro, nibindi, kandi bikoreshwa cyane mubikorwa bya peteroli na mashanyarazi.

12Cr1MoVG: Harimo chromium ndende, molybdenum na vanadium ibintu, hamwe nubushyuhe buhebuje bwo hejuru kandi burigihe kirekire.Imiyoboro idafite ibyuma yo muri iki cyiciro ikoreshwa kenshi mubushyuhe bwo hejuru hamwe n’umuvuduko mwinshi hamwe n’ibikoresho bikoresha ingufu za kirimbuzi, cyane cyane guhinduranya ubushyuhe, imiyoboro ya parike, nibindi.

Ibi byiciro bitandukanye byimiyoboro idafite ibyuma bikoreshwa cyane mugukora ibice byingenzi mubushyuhe bwo hejuru hamwe n’umuvuduko ukabije w’ibidukikije nk’ingufu, peteroli, n’ingufu za kirimbuzi bitewe n’imiterere yihariye y’imiti hamwe n’ubukanishi.Muguhitamo icyiciro cyiza cyicyuma, umutekano numutekano wibikoresho mugihe gikabije cyakazi birashobora kwizerwa, kandi ubuzima bwa serivisi burashobora kongerwa.
