Into malunga ne-S235JR

I-S235JR ngumgangatho we-European standard non-alloy structural steel, olingana nomgangatho wesizwe we-Q235B, eyintsimbi ye-carbon structural enomxholo ophantsi wekhabhoni.Isetyenziselwa i-welding, i-bolting kunye ne-riveting izakhiwo.

I-Carbon structural steel luhlobo lwentsimbi ye-carbon.Umxholo wekhabhoni umalunga ne-0.05% ~ 0.70%, kwaye ezinye zingaba phezulu njenge-0.90%.Inokwahlulwa ibe yintsimbi eqhelekileyo ye-carbon structural kunye ne-high-quality carbon structural steel.Isetyenziswa ngokubanzi kumzila kaloliwe, ibhulorho, iiprojekthi ezahlukeneyo zokwakha, ukuvelisa amacandelo esinyithi ahlukeneyo athwele umthwalo ongatshintshiyo, iindawo ezingabalulekanga koomatshini kunye neentsimbi zentsimbi jikelele ezingadingi unyango lobushushu.

Ibakala le-S235JR ipleyiti yensimbi ibonisa

"S": Intsimbi yaseYurophu esemgangathweni eqhelekileyo yekhabhoni;

“235″: amandla esivuno ngama-235, iyunithi: MPa;

"JR": impembelelo kwiqondo lokushisa eliqhelekileyo

3. I-S235JR yentsimbi yesigqeba somgangatho wesigqeba: EN10025 umgangatho

4. Isimo sokuhanjiswa kweplate yensimbi ye-S235JR: i-hot rolling, i-controlled rolling, i-normalization, njl njl.

5. S235JR ipleyiti yentsimbi ubukhulu iimfuno isalathiso isalathiso: Z15, Z25, Z35.

Uhlalutyo lokubunjwa kweekhemikhali ze-S235JR ipleyiti yensimbi

I-S235JR Ukwakhiwa kwemichiza:

S235JR ipleyiti yentsimbi umxholo wekhabhoni C: ≤ 0.17

S235JR ipleyiti yentsimbi umxholo wesilicon Si: ≤ 0.35

S235JR ipleyiti yentsimbi umxholo wemanganese Mn: ≤ 0.65

Umxholo we-Phosphorus we-S235JR ipleyiti yensimbi P: ≤ 0.030

S235JR ipleyiti yentsimbi umxholo wesulfure S: ≤ 0.030

3, Iipropati zeMechanical ze-S235JR ipleyiti yensimbi

Ukutyeba 8-420mm:

Isivuno samandla eMPa: ≥ 225

Amandla okuqina e-MPa: 360 ～ 510

Elongation%: ≥ 18

4, S235JR inkqubo yokuvelisa ipleyiti yentsimbi:

Ukuhamba kwenkqubo yokuvelisa: ukunyibilikiswa kwesithando sombane → LF/VD isiseko seziko → ukuphosa → ukucoca ingot → ukufudumeza ingot → ukuqengqeleka kwepleyiti → ukugqiba → ukusika isampulu → uhlolo lokusebenza → indawo yokugcina

5, S235JR ipleyiti yentsimbi ubukhulu ubungakanani intshayelelo ubukhulu

8-50mm * 1600-2200mm * 6000-10000mm

50-100mm * 1600-2200mm * 6000-12000mm

100-200mm * 2000-3000mm * 10000-14000mm

200-350mm * 2200-4020mm * 10000-18800mm

Ukuhlelwa komphezulu
Umphezulu oqhelekileyo (FA)
Umphezulu otyunjiweyo uvumelekile ukuba ube neziphene ezincinci kunye neendawo ezifana nemigodi, izibonda, imikrwelo, njl njl. ubunzulu bayo (okanye ubude) bungagqithisi kwisiqingatha sokunyamezela kobunzima bepleyiti yensimbi, kodwa ubuncinci obuvumelekileyo beplate yentsimbi kunye umcu wentsimbi uya kuqinisekiswa.
Umphezulu ophezulu (FB)
Umphezulu we-pickling uvumelekile ukuba ube neziphene zendawo ezingachaphazeli ukubunjwa, njengemikrwelo emincinci, i-indentations encinci, imigodi emincinci, amanqaku amancinci kunye nokwahlukana kombala.

Ukusetyenziswa kwezinto
Isetyenziselwa ikakhulu ukwakha, ibhulorho, iinqanawa, iinxalenye zesakhiwo sezithuthi, ukuvelisa izixhobo ezahlukeneyo, izixhobo zokusika, ukubumba kunye nezixhobo zokulinganisa.
