SS400 nuburyo bwo gushiraho ibimenyetso byibyuma byabayapani nibipimo byurubanza.
Ibyuma byubaka mubipimo byamahanga bikunze gushyirwa mubikorwa ukurikije imbaraga zingana, nka SS400 (byashyizweho nkibyo mubuyapani), aho 400 ihagarariye value Agaciro ntarengwa ka b ni 400MP. Ultra imbaraga zikomeye ibyuma bivuga σ Icyuma kitari munsi ya 1373 Mpa.
1. Ibisobanuro bitandukanye
SS400: SS400 nuburyo bwo kwerekana ibimenyetso byibyuma mubuyapani nuburinganire bwurubanza, bihwanye nicyuma cya Q235 mubushinwa.
Q235: Q235 ibyuma bisanzwe byubatswe byitwa nanone A3 ibyuma. Isanzwe isanzwe ya karubone yubatswe isahani ni ubwoko bwibyuma.
2. Ingingo zitandukanye z'umusaruro
Umusaruro wa Q235 urenze MPa 235, naho iya SS400 ni 245 MPa.
3. Imibare itandukanye
Umubare usanzwe wa Q235 ni GB / T700. Umubare usanzwe wa SS400 ni JIS G3101.
4. Imbaraga zitandukanye
SS400: Ibyuma byubatswe mubipimo byamahanga bikunze gushyirwa mubikorwa ukurikije imbaraga zingana, nka SS400 (byashyizweho nkibyo mubuyapani), aho 400 bisobanura σ agaciro ntarengwa ka b ni 400MPa. Ultra-high strength ibyuma bivuga σ B Icyuma kitari munsi ya 1373 Mpa.
Q235: Q yerekana imipaka yumusaruro wibi bikoresho. Ibikurikira 235 bivuga agaciro k'umusaruro w'ibi bikoresho, ni 235MPa. Agaciro k'umusaruro kazagabanuka hamwe no kwiyongera k'ubunini bwibintu. Bitewe na karubone iringaniye, ibintu byuzuye nibyiza, kandi imbaraga, plastike hamwe nudusudira twahujwe neza.
5. Kugereranya ibigize imiti hagati ya Q235 na SS400
Q235B karubone C: ntabwo irenze 0.18
Q235B Mn: 0.35-0.80
Q235B silicon Si: ntibirenze 0.3
Q235B sulfure S: ntibirenza 0.04
Q235B fosifore P: ntabwo irenze 0.04
SS400 sulfure S: ntibirenza 0.05
SS400 Fosifore P: ntarenze 0.05
6. Kugereranya imiterere yubukanishi hagati ya Q235 na SS400
Q235 itanga imbaraga: ntabwo iri munsi ya 185.
Q235 imbaraga zingana: 375-500
Kurambura Q235: ntibiri munsi ya 21
SS400 itanga umusaruro: ntabwo iri munsi ya 215.
SS400 imbaraga zingana: 400-510
Kurambura SS400: ntibiri munsi ya 17
