Umgangatho waseJapan SS400 kunye nomgangatho wesizwe Q235 yintoni umahluko?

I-SS400 yindlela yokumakisha yezixhobo zentsimbi zaseJapan kunye nomgangatho wesigwebo.
Iintsimbi zesakhiwo kwimigangatho yangaphandle zihlala zihlelwa ngokwamandla e-tensile, njenge-SS400 (ephawulwe ngolo hlobo eJapan), apho i-400 imele σ Ixabiso elincinci le-b yi-400MP.Intsimbi eyomelele kakhulu ephezulu ibhekisa kwi σ Intsimbi engekho ngaphantsi kwe-1373 Mpa.

1. Iintsingiselo ezahlukeneyo
I-SS400: I-SS400 yindlela yokumakisha izinto zensimbi eJapan kunye nomgangatho wokugweba, olingana ne-Q235 yensimbi yaseChina.
I-Q235: I-Q235 yentsimbi eqhelekileyo ye-carbon structural ibizwa ngokuba yintsimbi ye-A3.I-carbon structural iron plate yentsimbi eqhelekileyo luhlobo lwempahla yentsimbi.

2. Amanqaku esivuno ahlukeneyo
Inqaku lesivuno se-Q235 likhulu kune-235 MPa, ngelixa i-SS400 i-245 MPa.

3. Amanani asemgangathweni ahlukeneyo
Inani eliqhelekileyo le-Q235 yi-GB/T700.Inani eliqhelekileyo le-SS400 yi-JIS G3101.

4. Amandla ahlukeneyo
I-SS400: Iintsimbi zesakhiwo kwimigangatho yangaphandle zihlala zihlelwa ngokwamandla e-tensile, njenge-SS400 (ephawulwe ngolo hlobo eJapan), apho i-400 ithetha σ Ixabiso elincinci le-b yi-400MPa.Intsimbi eyomelele kakhulu ephezulu ibhekisa kwi-σ B Steel engekho ngaphantsi kwe-1373 Mpa.
I-Q235: Q imele umda wesivuno sesi sixhobo.Okulandelayo i-235 ibhekiselele kwixabiso lesivuno sale nto, malunga ne-235MPa.Ixabiso lesivuno liya kuncipha ngokunyuka kwezinto eziphathekayo.Ngenxa yomxholo wekhabhoni ophakathi, iipropathi ezibanzi zilungile, kwaye amandla, iplastiki kunye nepropathi ye-welding ihambelana kakuhle.

5. Ukuthelekiswa kokwakhiwa kweekhemikhali phakathi kwe-Q235 kunye ne-SS400
Q235B carbon C: hayi ngaphezulu kwe-0.18
Q235B Mn: 0.35-0.80
Q235B silicon Si: akukho ngaphezu kwe-0.3
Q235B isulfure S: hayi ngaphezulu kwe-0.04
Q235B phosphorus P: akukho ngaphezu kwe-0.04
SS400 isulfure S: hayi ngaphezulu kwe-0.05
SS400 Phosphorus P: hayi ngaphezulu kwe-0.05

6. Ukuthelekiswa kweempawu zemishini phakathi kwe-Q235 kunye ne-SS400
Q235 amandla isivuno: hayi ngaphantsi kwe 185
Q235 amandla okuqina: 375-500
