QN1803 (304D) Isahani idafite ibyuma
1. Ibisobanuro:
Icyiciro gishya cyibicuruzwa QN1803 nicyo azote ya mbere ku isi ya azote, irwanya ruswa nyinshi, nikel ikiza nikel austenitike idafite ibyuma.
Hashingiwe ku kwemeza kurwanya ruswa ihwanye na 304 ibyuma bitagira umwanda, imbaraga zibikoresho ziratera imbere, hamwe nibikoresho
igiciro kiragabanuka, bigatuma gikoreshwa neza kandi kirushanwe kumasoko kuruta 304 ibyuma bitagira umwanda.
Ibishushanyo mbonera bishya byerekana ibicuruzwa: azote nyinshi (≥2000ppm), chromium ndende (≥18%), nikel yo hagati (~ 3.0%) n'umuringa muremure (.51.5%).
Binyuze kuri sisitemu ya R&D yububiko bwa Thermo-Calc thermodynamic icyiciro cyo kubara igishushanyo mbonera cyo kubara no gusesengura amakuru yubushakashatsi, guhindura
kuvanga ibintu bya buri cyiciro ntigishobora kunoza gusa kwangirika kwibicuruzwa, ahubwo binatanga imbaraga zumusaruro wa QN1803
inshuro zirenga 1.3 zo muri 304.
QN1803 ifite ibintu bikurikira:
1) ibishishwa byangirika bihwanye na PREN = Cr + 3.3Mo + 30N-Mn iri hejuru ya 19.0, ifite byibuze irwanya ruswa imwe na 304
ibyuma.
2) kurwanya ruswa imwe muri acide hydrochloric acide, acide acide sulfurike, acide acike + umunyu nibindi bidukikije ni byiza cyane kuruta
304 ibyuma.
3) kurwanya ruswa biruta 304 muburyo bukoreshwa nyuma yo kunama, kashe, imiterere ikomeye nubundi bukonje.
4) imbaraga z'umusaruro zirenze inshuro 1,3 z'ibyuma 304 bitagira umwanda, kandi bifite uburebure butari munsi ya 45%. Kwambara ukurwanya kandi
imikorere yumunaniro iruta 304 ibyuma bidafite ingese.
5) imikorere myiza yo gusudira, imbaraga nyuma yo gusudira zirenze iz'ibyuma 304 bidafite ingese, kandi kurwanya ruswa ni
ugereranije niy'ibyuma 304 bidafite ingese.
