1. Kumenyekanisha muri make icyuma cya S355J0W:
S355J0W nicyuma gisanzwe cyu Burayi cyangiza ikirere cyangirika, kikaba ari icyapa cyangiza ikirere.Nicyuma giciriritse gikozwe mukongeramo umubare munini wibintu bivangwa nibyuma bisanzwe.Kurwanya kwangirika kwikirere kwicyuma cyikubye inshuro 2-8 icyuma gisanzwe cya karubone, kandi gifite imiterere yubukanishi, ibikoresho byo gusudira, nibindi, kandi igihe kinini, niko bigaragara ingaruka zo kurwanya ruswa.
2. S355J0W yateje imbere ibyuma byangiza ikirere
Umubare munini wibintu bivangavanze byongewe mubyuma, nka P, Cu, Cr, Ni, Mo, kugirango hongerwe imbaraga zo kurwanya ruswa, kandi bitewe nikirere cy’ikirere, hazongera kubaho okiside ikingira ikingira. icyuma fatizo.
3. Imiterere yo gutanga ya S355J0W:
Yatanzwe muburyo bushyushye, busanzwe cyangwa busanzwe buzunguruka.
Bane, S355J0W icyuma gisanzwe:
S355J0W ishyira mubikorwa EN10025-5: 2004.
5. S355J0W yateje imbere ibyuma byangiza ikirere
Umubare munini wibintu bivangavanze byongewe mubyuma, nka P, Cu, Cr, Ni, Mo, kugirango hongerwe imbaraga zo kurwanya ruswa, kandi bitewe nikirere cy’ikirere, hazongera kubaho okiside ikingira ikingira. icyuma fatizo.
6. Ubushobozi bwacu bwo gutanga:
1. Icyuma kiboneka cyerekana icyapa: uburebure bwa 8-700mm, ubugari 1500-4020mm, uburebure bwa 4000mm-17000mm, uburemere bwa toni 30.00.Ibyuma binini byo gupima nabyo birahari bisabwe.
2. Ubwoko bwibyuma biboneka: ibyuma byubatswe byububiko bwa karubone, ibyuma bito bito cyane-byuma byuma, ibyapa byicyuma kubiraro, ibyapa byubwubatsi, ibyapa byubwubatsi bwubwato hamwe na platifomu, ibyapa byibyuma hamwe nubwato bwumuvuduko, ibyuma amasahani yububiko, ibyuma byibyuma byubatswe, Hano hari ibyiciro 12 byibyuma byumuyoboro wa peteroli na gazi, ibyuma bikomeye kandi bikomeye cyane ibyuma, ibyuma birwanya ruswa, hamwe nibyuma, hamwe nibyuma birenga 300 murugo kandi ibirango by'amahanga.
3. Iraboneka kubisabwa kugirango hamenyekane inenge, Z15-Z35 yuburebure bwicyerekezo cyibisabwa, imbaraga nyinshi nibisabwa bikomeye hamwe nibindi byuma.
4. Irashobora gutangwa hakurikijwe ibipimo byigihugu, ibipimo bya metallurgjiya, ibipimo byabanyamerika AISI / ASME / ASTM, Ubuyapani JIS, Ubudage busanzwe DIN, Igifaransa NF, BS BS, Abongereza EN, ISO mpuzamahanga nibindi bipimo.
