"Ubunyangamugayo, guhanga udushya, imbaraga, no gukora neza" birashobora kuba igitekerezo gihoraho cyikigo cyacu kugeza igihe kirekire cyo kubyaza umusaruro hamwe nabakiriya kugirango basubiranamo kandi bunguka inyungu kubisubizo bitanga. Ubu dufite ibarura rinini rya Cr Mo alloy ibyuma kugirango twuzuze ibyo abakiriya bacu bakeneye kandi bakeneye. Hamwe nabakozi bize neza, bashya kandi bafite ingufu, twashinzwe ibintu byose byo gutanga imiyoboro. Numutungo munini wo murwego rwohejuru hamwe na serivise nyinshi, tugana ku ntego yo kuba umwe mubatanga imiyoboro minini itanga isi. Twumva neza ibitekerezo byabakiriya bacu kandi dutanga ibisubizo ako kanya. Uzahita wumva serivisi yacu yubuhanga kandi yitonze.

Kubijyanye n'umutungo wa Cr Mo umuyoboro, hari ibintu byinshi byuma bigira ingaruka. Isano iri hagati yimashini yimiyoboro nicyuma cyingenzi nkuko bikurikira:

Carbone (C): Ibirimo bya karubone mubyuma byiyongera, ingingo yumusaruro, imbaraga zingana nubukomezi byiyongera, ariko plastike ningaruka zigabanuka. Iyo karubone irenze 0.23%, imikorere yo gusudira ibyuma irangirika, niba rero ikoreshwa mugusudira Ibirimo bya karubone yibikoresho byubatswe buke buke muri rusange ntibirenza 0,20%. Ibirimo byinshi bya karubone bizagabanya kandi kwangirika kwikirere kwangirika kwicyuma, kandi ibyuma bya karuboni nyinshi mukibuga cyafunguye biroroshye kubora; mubyongeyeho, karubone irashobora kongera ubukonje bukabije no gusaza kwicyuma.
Silicon (Si): Silicon yongeweho nkibintu bigabanya na deoxidizer mugikorwa cyo gukora ibyuma, bityo ibyuma byishe birimo silikoni 0.15-0.30%. Silicon irashobora kuzamura cyane imipaka ya elastike, umusaruro utanga nimbaraga zicyuma cyicyuma, bityo ikoreshwa cyane nkibyuma byoroshye. Kwiyongera kwinshi kwa silicon bizagabanya imikorere yo gusudira ibyuma.
Manganese (Mn). Mubikorwa byo gukora ibyuma, manganese ni deoxidizer nziza na desulfurizer. Mubisanzwe, ibyuma birimo 0.30-0.50% manganese. Manganese irashobora kongera imbaraga nubukomezi bwibyuma, kongera ubukana bwibyuma, kunoza imikorere ishyushye yicyuma, no kugabanya imikorere yo gusudira ibyuma.
Fosifore (P): Mubisanzwe, fosifore nikintu cyangiza mubyuma, byongera ubukonje bukabije bwibyuma, byangiza imikorere yo gusudira, bigabanya plastike, kandi bikangiza imikorere yubukonje bukonje. Kubwibyo, ibirimo fosifore mubyuma mubisanzwe birasabwa kuba munsi ya 0.045%, kandi ibyangombwa byicyuma cyiza biri hasi.
Amazi ya sufuru (S): Amazi na yo ni ikintu cyangiza mu bihe bisanzwe. Kora ibyuma bishyushye, bigabanye guhindagurika kwicyuma no gukomera, kandi utere ibice mugihe cyo guhimba no kuzunguruka. Amazi ya sufuru nayo yangiza imikorere yo gusudira, kugabanya kurwanya ruswa. Kubwibyo, ibirimo sulfure muri rusange birasabwa kuba munsi ya 0,045%, kandi ibyangombwa byibyuma byujuje ubuziranenge biri hasi. Ongeraho 0.08-0.20% sulfure mubyuma birashobora kunoza imashini, kandi mubisanzwe byitwa ibyuma bikata kubusa.
Vanadium (V): Kongera vanadium mubyuma birashobora gutunganya ingano yimiterere no kunoza imbaraga nubukomere.
Niobium (Nb): Niobium irashobora gutunganya ibinyampeke no kunoza imikorere yo gusudira.
Umuringa (Cu): Umuringa urashobora kunoza imbaraga no gukomera. Ikibi ni uko ikunda guhura n'ubushyuhe mugihe cyo gukora gishyushye, kandi ibirimo umuringa mubyuma bishaje akenshi usanga biri hejuru.
Aluminium (Al): Aluminium ni deoxidizer ikoreshwa cyane mu byuma. Umubare muto wa aluminiyumu wongeyeho ibyuma kugirango utunganyirize ingano no kunoza ingaruka zikomeye.
