Iyini impahla ye-SS400? Liyini ibanga lensimbi lasekhaya elihambisanayo le-SS400?

I-SS400ipuleti lensimbi elijwayelekile laseJapan elihambisana ne-JIS G3101. Ihambisana ne-Q235B esezingeni likazwelonke laseShayina, inamandla aqinile angama-400 MPa. Ngenxa yokuqukethwe kwayo kwekhabhoni emaphakathi, inikezela ngezakhiwo ezibanzi ezilinganiswe kahle, ifinyelela ukusebenzisana okuhle phakathi kwamandla, i-ductility, kanye nokushisela, okuyenza ibe yibanga elisetshenziswa kakhulu.
Umehluko phakathiQ235b Ss400:

Amazinga ahlukene:
Q235Bilandela i-Chinese National Standard (GB/T700-2006). “Q” isho amandla esivuno, '235' ikhombisa amandla amancane esivuno angama-235 MPa, futhi “B” isho izinga lekhwalithi. I-SS400 ilandela i-Japan Industrial Standard (JIS G3101), lapho i-“SS” isho insimbi yesakhiwo futhi “400” ikhombisa amandla aqinile angaphezu kuka-400 MPa. Ezifanekisweni zepuleti lensimbi elingu-16mm, i-SS400 ibonisa amandla okukhiqiza angu-10 MPa ngaphezu kwe-Q235A. Kokubili amandla aqinile nobude kudlula lawo e-Q235A.

 

Izici Zokusebenza:

Kuzinhlelo zokusebenza ezingokoqobo, womabili amabanga abonisa ukusebenza okufanayo futhi avame ukuthengiswa futhi acutshungulwe njengensimbi evamile ye-carbon steel, umehluko ubonakala kancane. Kodwa-ke, ngokombono wencazelo ejwayelekile, i-Q235B igcizelela amandla esivuno, kuyilapho i-SS400 ibeka kuqala amandla aqinile. Kumaphrojekthi anezidingo ezinemininingwane yezakhiwo zemishini yensimbi, ukukhetha kufanele kusekelwe ezidingweni ezithile.

 

Amapuleti ensimbi e-Q235A anobubanzi bokusebenza obuncane kune-SS400. I-SS400 empeleni ilingana ne-Q235 yaseChina (ilingana nokusetshenziswa kwe-Q235A). Nokho, izinkomba ezithile ziyehluka: I-Q235 icacisa imikhawulo yokuqukethwe yama-elementi afana no-C, Si, Mn, S, no-P, kuyilapho i-SS400 idinga kuphela u-S no-P ukuthi babe ngaphansi kuka-0.050. I-Q235 inamandla okukhiqiza angaphezu kwama-235 MPa, kuyilapho i-SS400 ifinyelela ku-245 MPa. I-SS400 (insimbi yesakhiwo esijwayelekile) isho insimbi yesakhiwo esijwayelekile enamandla angaphezu kwama-MPa angama-400. I-Q235 isho insimbi evamile yesakhiwo sekhabhoni enamandla okukhiqiza angaphezu kwama-235 MPa.

 

Izinhlelo zokusebenza ze-SS400: I-SS400 ivamise ukugoqelwa ibe yizintambo zocingo, amabha ayindilinga, ama-square, ama-flat, ama-engeli, ama-I-beam, izigaba zesiteshi, insimbi yohlaka lwamafasitela, nezinye izimo zesakhiwo, kanye namapuleti anobukhulu obuphakathi. Isetshenziswa kakhulu kumabhuloho, imikhumbi, izimoto, izakhiwo kanye nezakhiwo zobunjiniyela. Isebenza njengemigoqo eqinisayo noma yokwakha ama-trusses ophahleni lwasefekthri, imibhoshongo yamandla kagesi aphezulu, amabhuloho, izimoto, amabhayela, iziqukathi, imikhumbi, njll. Ibuye isetshenziswe kabanzi ezingxenyeni zemishini ezinezidingo zokusebenza eziqinile kancane. Izinsimbi zeBanga C kanye no-D nazo zingasetshenziselwa izinhlelo ezithile ezikhethekile.
