Ikibanza cya garanti yo kugurisha 42CrMo ikora ibyuma bikora imiyoboro
Intego ya 42CrMo umuyoboro wicyuma udafite kashe: ibyuma bidasanzwe byikiraro ni "42CrMo", ibyuma bidasanzwe byo gukingira imodoka ni "42CrMo", naho ibyuma bidasanzwe byubwato ni "42CrMo". Ubu bwoko bwibyuma butezimbere imiterere yicyuma muguhindura karubone (c). Kubwibyo, ukurikije ibirimo karubone, ubu bwoko bwibyuma bushobora kugabanywamo: ibyuma bike bya karubone - ibirimo karubone muri rusange biri munsi ya 0.25%, nkibyuma 10 na 20; Icyuma giciriritse giciriritse - ibirimo karubone muri rusange biri hagati ya 0,25 ~ 0,60%, nka 35 na 45; Ibyuma byinshi bya karubone - ibirimo karubone muri rusange birenze 0,60%. Ubu bwoko bwibyuma ntabwo bukoreshwa mugukora imiyoboro yicyuma.
42CrMo ni ubwoko bw'ibyuma. Icyuma cyahoze cyitwa ibyuma. Uburyo bwitwa Q345B. Ibikoresho bisa ni Q345A, Q345C na Q345E. Ikimenyetso cyiza cyiza a, B, C, de byerekana ko ikizamini cyingaruka kidakenewe. Ubushyuhe bwikigereranyo ni + 20 ° 0 ° kugeza 20 ° 40 ° ABCD yerekana icyiciro cyiza Q235. Urwego rw'ubuziranenge rugabanijwemo ibyiciro bine A, B, C na D. kuva a kugeza D byerekana ko ubuziranenge buva hasi kugeza hejuru.
A - gutanga s, P, C, Mn, Si ibigize imiti na Fu, FY δ 5 （δ 10), ikizamini cya 1800 cyo kugonda ubukonje gishobora gutangwa ukurikije ibyo umuguzi akeneye, ariko nta ngaruka zoguhindura ingufu, nibirimo karubone n'ibirimo manganese ntabwo bifatwa nkibisabwa.
B - gutanga s, P, C, Mn, Si imiti yimiti na Fu, FY δ 5 （δ 10), ikizamini cya bend 180 'ikizamini. Ingufu zingaruka AK ≥ 27j kuri + 200C nazo ziratangwa
C - usibye ibisabwa mubyiciro B, ingufu zingaruka AK ≥ 27j kuri 00C nazo ziratangwa.
D - usibye ibisabwa murwego B, ingaruka zingufu AK ≥ 27j kuri - 200C nazo ziratangwa. E - usibye ibisabwa kurwego B, ingaruka zingufu AK ≥ 27j kuri - 400C nazo ziratangwa. Ibisobanuro bishyushye byo gukora
Ubushyuhe bwo gushyuha ni 1150 ~ 1200 ° C, ubushyuhe bwo gutangira ni 1130 ~ 1180 ° C, naho ubushyuhe burangira ni> 850 ° C, φ> Gukonja buhoro kuri 50mm.
Ubushyuhe busanzwe ni 850 ~ 900 ° C, kandi itanura risohoka kugirango hakonje umwuka.
Ubushyuhe bwo hejuru burambuye
Ubushyuhe bwo hejuru ni 680 ~ 700 ° C, kandi itanura risohoka kugirango hakonje umwuka.
Gushyushya ubushyuhe 680 ~ 700 ° C, kuzimya ubushyuhe 840 ~ 880 ° C, gukonjesha amavuta, ubushyuhe bwa 580 ° C, gukonjesha amazi cyangwa gukonjesha amavuta, gukomera ≤ 217hbw.
Ibisobanuro byo gushimangira no gukaza umurego ukoresheje ubushyuhe bwo hasi
Kuzimya ubushyuhe 900 ° C, ubushyuhe 560 ° C, ubukana (37 ± 1) HRC
Ibisobanuro byo kuzimya induction
Kuzimya ubushyuhe 900 ° C, ubushyuhe bwo hejuru 150 ~ 180 ° C, ubukana 54 ~ 60HRC.
