42CRMO Umuyoboro udafite ibyuma
Intego ya 42crmo idafite umuyoboro wicyuma: Icyiciro cyihariye cyicyuma kubiraro ni "42crmo", icyiciro cyihariye cyicyuma cyimodoka ni "42CRmo", naho icyiciro cyihariye cyicyuma cyumuvuduko ni "42Crmo".Ubu bwoko bwibyuma bushingira ku guhindura karubone (C) kugirango tunoze imiterere yubukorikori.Kubwibyo, ukurikije urwego rwibirimo bya karubone, ubu bwoko bwibyuma bushobora kugabanywamo: Ibyuma bya karuboni nkeya-ibyuka bya karubone muri rusange ntibiri munsi ya 0.25%, nkibyuma 10, 20, nibindi.;icyuma giciriritse giciriritse-karubone muri rusange kiri hagati ya 0,25 na 0,60%, nka 35, 45 ibyuma, nibindi.;ibyuma byinshi bya karubone-karubone muri rusange birenze 0,60%.Ubu bwoko bwibyuma ntabwo bukoreshwa mugukora imiyoboro yicyuma.
Nta bushyuhe bugaragara bugaragara, guhindura ibintu bito mugihe cyo kuzimya, kugabanya umunaniro mwinshi hamwe no kurwanya ingaruka nyinshi nyuma yo kuzimya no kuvura ubushyuhe, ubukana bwiza bwubushyuhe bwo hasi, imbaraga zo hejuru cyane nimbaraga zirambye mubushyuhe bwinshi.Ubusanzwe ibyuma bikoresha kuzimya hejuru nyuma yo kuzimya no gushyuha nka gahunda yo kuvura ubushyuhe.
42crmo ni ibikoresho mubyuma.Kera, izina ryibyuma.Izina ni: Q345B, ibikoresho bisa ni Q345a, Q345c, Q345e, ikimenyetso cyerekana ubuziranenge ABCDE bivuze ko ubushyuhe bwikizamini bwingaruka budasabwa kuba dogere 20 dogere 0 dogere -20 dogere 40 dogere 40 ABCD yerekana urwego rwiza Q235 urwego rwubuziranenge Hariho inzego enye za A, B, C, D, kuva A kugeza D ko ubuziranenge buva hasi kugeza hejuru.
Ibisabwa mu nzego zinyuranye ni ibi bikurikira:
A —— Tanga imiti ya S, P, C, Mn, Si na fu, fy, δ5 (δ10), ukurikije ibyo umuguzi akeneye, ikizamini cya 1800 gikonje gishobora gutangwa, ariko nta ngaruka zoguhindura ingufu, karubone ibirimo nibirimo manganese ntibifatwa nkibisabwa.
B —— Tanga S, P, C, Mn, Si ibigize imiti na fu, fy, δ5 (δ10), ikonje igoramye 180 'ikizamini.Itanga kandi ingufu zingaruka kuri + 200C, Ak≥27J
C-Usibye ibisabwa bimwe nicyiciro B, inatanga ingufu zingaruka Ak≥27J kuri 00C.
D ---- Usibye ibisabwa kurwego B, inatanga ingufu zingaruka Ak≥27J kuri -200C.E ---- Usibye ibisabwa kurwego B, inatanga ingufu zingaruka Ak≥27J kuri -400C.
Aho imiyoboro ya 42crmo idafite icyuma hamwe nu miyoboro isanzwe yicyuma ikoreshwa: Imiyoboro yicyuma igabanijwemo ubukonje bukonje kandi buzunguruka.

Imiyoboro inyuranye ivanze 16Mn, 27SiMn, 15CrMo, 35CrMo, 12CrMovG, 20G, 40Cr, 12Cr1MoV, 15CrMoG imiyoboro y'ibyuma igabanijwemo imiyoboro y'icyuma idafite ubudodo hamwe n'imiyoboro y'ibyuma isudira hakurikijwe inzira zitandukanye.
Imiyoboro y'icyuma idafite icyerekezo ni imiyoboro y'icyuma idafite icyuma ikozwe mu byuma, bilet cyangwa inkoni z'icyuma zisobekeranye.
