I-SS400 ejwayelekile yaseJapan kanye ne-Q235 ejwayelekile kazwelonke yimuphi umehluko?

I-SS400 iyindlela yokumaka yezinto zensimbi zaseJapane nezinga lokwahlulela.
Izinsimbi zesakhiwo ezindinganisweni zangaphandle zivame ukuhlukaniswa ngokwamandla e-tensile, njenge-SS400 (imakwe kanjalo e-Japan), lapho u-400 emele u-σ Inani elincane 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 (imakwe kanjalo e-Japan), lapho u-400 esho ukuthi σ Inani eliphansi lika-b ngu-400MPa.Insimbi enamandla amakhulu 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
Q235B Silicon Si: 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
