1. Icyuma kubwimbaraga rusange zuzuye
Ibyuma rusange byimbaraga zubatswe bigabanijwemo ibyiciro bine: A, B, D na E. Imbaraga zumusaruro (zitari munsi ya 235N / mm ^ 2) muribi byiciro bine byibyuma ni kimwe nimbaraga zingana (400 ～ 520N / mm ^ 2). , ariko imbaraga zingaruka kubushyuhe butandukanye ziratandukanye;
Ibyuma-bikomeye byubatswe byubatswe bigabanijwe mubyiciro byimbaraga ukurikije imbaraga nkeya yumusaruro, kandi buri cyiciro cyingufu kigabanyijemo amanota A, D, E, F4 ukurikije ingaruka zikomeye.
Imbaraga z'umusaruro wa A32, D32, E32, na F32 ntabwo ziri munsi ya 315N / mm ^ 2, kandi imbaraga zingana ni 440-570N / mm ^ 2. Ingaruka zikomeye zishobora kugerwaho kuri -40 °, -60 °;
Imbaraga z'umusaruro wa A36, D36, E36 na F36 ntabwo ziri munsi ya 355N / mm ^ 2, kandi imbaraga zingana ni 490 ～ 620N / mm ^ 2. Ingaruka zikomeye zishobora kugerwaho kuri -40 °, -60 °;
Imbaraga z'umusaruro wa A40, D40, E40, na F40 ntabwo ziri munsi ya 390N / mm ^ 2, kandi imbaraga zingana ni 510 ~ 660N / mm ^ 2. Ingaruka zikomeye zishobora kugerwaho kuri -40 ° na -60 °.
usibye,
Imbaraga zikomeye zazimye kandi zifite ubushyuhe bwo gusudira: A420, D420, E420, F420; A460, D460, E460, F460; A500, D500, E500, F500; A550, D550, E550, F550; A620, D620, E620, F620; A690, D690, E690, F690;
Icyuma cyo gutekesha no kumashanyarazi: 360A, 360B; 410A, 410B; 460A, 460B; 490A, 490B; 1Cr0.5Mo, 2.25Cr1Mo
Ibyuma byububiko: Mubisanzwe, ibyuma byavuzwe haruguru birashobora gukoreshwa;
Ubushyuhe buke bwo gukomera: 0.5NiA, 0.5NiB, 1.5Ni, 3.5Ni, 5Ni, 9Ni;
Icyuma cya Austenitike:
Duplex idafite ibyuma: 00Cr22Ni5Mo3N, 00Cr25Ni6Mo3Cu, 00Cr25Ni7Mo4N3.
Isahani yambaye ibyuma: ikwiranye na kontineri n'ibigega by'imizigo bitwara imiti;
Icyuma cya Z-Icyerekezo: Nicyuma cyakorewe ubuvuzi bwihariye (nko kuvura calcium, vacuum degassing, argon stirring, nibindi) hamwe no kuvura ubushyuhe bukwiye hashingiwe ku cyiciro runaka cyibyuma byubatswe (bita ibyuma byababyeyi).
