I-SS400 iyindlela yokumaka yezinto zensimbi zaseJapane nezinga lokwahlulela.
Izinsimbi zesakhiwo ezindinganisweni zangaphandle zivame ukuhlukaniswa ngokwamandla aqinile, njenge-SS400 (imakwe kanjalo e-Japan), lapho u-400 emele u-σ Inani eliphansi lika-b ngu-400MP. Insimbi enamandla amakhulu kakhulu ibhekisa ku-σ Steel engekho ngaphansi kuka-1373 Mpa.
1. Izincazelo ezahlukene
I-SS400: I-SS400 iyindlela yokumaka yezinto zensimbi e-Japan kanye nezinga lokwahlulela, elilingana nensimbi ye-Q235 e-China.
I-Q235: I-Q235 insimbi evamile yesakhiwo se-carbon nayo ibizwa ngokuthi i-A3 steel. I-Ordinary carbon structural steel plain plate iwuhlobo lwensimbi.
2. Amaphuzu esivuno ahlukene
Iphuzu lokukhiqiza le-Q235 likhulu kuno-235 MPa, kuyilapho lelo le-SS400 lingama-245 MPa.
3. Izinombolo ezijwayelekile ezihlukene
Inombolo ejwayelekile ye-Q235 yi-GB/T700. Inombolo ejwayelekile ye-SS400 yi-JIS G3101.
4. Amandla ahlukene
I-SS400: Izinsimbi zesakhiwo ezindinganisweni zangaphandle zivame ukuhlukaniswa ngokwamandla aqinile, njenge-SS400 (ephawulwe kanjalo e-Japan), lapho u-400 esho ukuthi σ inani elincane lika-b ngu-400MPa. Insimbi yamandla aphezulu kakhulu ibhekisa ku-σ B Steel engekho ngaphansi kuka-1373 Mpa.
Q235: Q imele umkhawulo wesivuno salokhu kwaziswa. Okulandelayo okungu-235 kubhekisele enanini lesivuno salokhu kwaziswa, okungaba ngu-235MPa. Inani lesivuno lizokwehla ngokunyuka kokuqina kwempahla. Ngenxa yokuqukethwe kwekhabhoni emaphakathi, izakhiwo ezibanzi zinhle, futhi amandla, ipulasitiki kanye nezakhiwo zokushisela zihambisana kahle.
5. Ukuqhathaniswa kokwakheka kwamakhemikhali phakathi kwe-Q235 ne-SS400
Q235B carbon C: akukho ngaphezu kuka-0.18
Q235B Mn: 0.35-0.80
I-silicon ye-Q235B: akukho ngaphezu kwe-0.3
Q235B sulphur S: akukho ngaphezu kwe-0.04
Q235B phosphorus P: akukho ngaphezu kuka-0.04
I-SS400 sulphur S: akukho ngaphezu kwe-0.05
SS400 Phosphorus P: akukho ngaphezu kwe-0.05
6. Ukuqhathaniswa kwezakhiwo zemishini phakathi kwe-Q235 ne-SS400
Q235 amandla esivuno: hhayi ngaphansi kuka-185.
Q235 amandla okubamba: 375-500
Ubude be-Q235: hhayi ngaphansi kuka-21
Amandla esivuno se-SS400: akukho ngaphansi kuka-215.
Amandla we-SS400: 400-510
Ubude be-SS400: hhayi ngaphansi kuka-17
Isikhathi sokuthumela: Dec-21-2023
