ASTM A333 Icyiciro cya 6ni ibikoresho byo mu cyuma cya karuboni bikoreshwa mu buryo bwa cryogenic n'ubundi buryo busaba gukomera. Bishobora gukoreshwa ahantu hafite ubushyuhe bugera kuri -45°C (-50°F) kandi biboneka mu buryo budafite umugozi n'ubworoshye.
ASTM A333 ishobora gukoreshwa muinzira idasobanyije cyangwa ivanze.
Uburyo bwo gukora imiyoboro y'icyuma idahindagurika bugabanyijemo ibice bibiri: ubushyuhe n'ubukonje. Kandi bigomba kugaragara hejuru y'ikimenyetso.
Imiyoboro y'icyuma idafunze ni yo ikoreshwa mbere na mbere mu bidukikije bikomeye, mu bihe bigoye, no mu gihe hakenewe imiyoboro minini cyane.
ASTM A333 GR.6 igomba kuvurwa hakurikijwe bumwe mu buryo bukurikira kugira ngo igenzure imiterere yayo:
● Guhindura ubushyuhe: Shyushya kugeza ku bushyuhe bumwe bwa dogere selisiyusi 815, hanyuma ukonje mu kirere cyangwa mu cyumba gikonjesha cy'itanura rigenzurwa n'ikirere.
● Gushyushya nyuma yo kuvugurura: Nyuma yo kuvugurura, bishobora kongera gushyushya kugeza ku bushyuhe bukwiye nk'uko uwabikoze abyifuza.
● Ku bijyanye n'imikorere idahindagurika, ibi bishobora kugerwaho hakoreshejwe kugenzura ubushyuhe bw'imirimo ishyushye n'ibikorwa byo kurangiza bishyushye ku buryo ubushyuhe bwa nyuma buri hagati ya 1550 na 1750 °F [845 na 945 °C] hanyuma bugakonjeshwa mu kirere cyangwa mu itanura rigenzurwa n'ikirere kuva ku bushyuhe bwa mbere bwa nibura 1550 °F [845 °C].
● Gushyushya nyuma yo gukoresha ubushyuhe bugenzuwe no kurangiza gukoresha ubushyuhe bishobora kongera gushyushywa kugeza ku bushyuhe bukwiye nk'uko uwabikoze abyifuza.
● Kuzimya no gushyushya: Aho gukoresha uburyo ubwo aribwo bwose bwavuzwe haruguru, imiyoboro idakora neza yo mu cyiciro cya 1, 6, na 10 ishobora kuvugururwa hakoreshejwe ubushyuhe bungana nibura na 815 °C, hanyuma ikabuzimya mu mazi hanyuma igashyushya kugeza ku bushyuhe bukwiye.
AKuri buri kugabanuka kwa 0.01% ya karuboni munsi ya 0.30%, kwiyongera kwa 0.05% ya manganese hejuru ya 1.06% byakwemererwa kugera kuri 1.35% ya manganese.
CKu bwumvikane hagati y’uruganda n’umuguzi, igipimo ntarengwa cya niobium gishobora kongerwa kugeza kuri 0.05% ku isesengura ry’ubushyuhe na 0.06% ku isesengura ry’ibicuruzwa.
DAmagambo Niobium (Nb) na Columbium (Cb) ni amazina asimburana y'ikintu kimwe.
Umutungo wo gukurura

Uburebure hano ni bwo buryo bw'ibanze gusa.
Ibindi Bigeragezo
ASTM A333 ifite ikizamini cyo kugorora, ikizamini cyo gukubita, hiyongereyeho ikizamini cyo gukurura.
Ibi bikurikira ni ubushyuhe bw'ibizamini by'ingaruka ku rwego rwa 6:
