S235JR ke tšepe e tloaelehileng ea Europe e se nang alloy, e lekanang le maemo a naha a Q235B, e leng tšepe e nang le khabone e nang le khabone e tlase. E sebelisoa bakeng sa meaho ea welding, bolting le riveting.
Carbon structural steel ke mofuta oa tšepe ea carbon. Khabone e ka ba 0.05% ~ 0.70%, 'me e meng e ka ba holimo ho 0.90%. E ka aroloa ka tšepe e tloaelehileng ea carbon structural le tšepe ea boleng bo holimo ea carbon. E sebelisoa haholo ho seporo, borokho, merero e fapaneng ea kaho, ho etsa likarolo tse fapaneng tsa tšepe tse jereng mojaro o sa fetoheng, likarolo tse seng tsa bohlokoa tsa mochini le litšepe tse akaretsang tse sa hlokeng kalafo ea mocheso.
Sehlopha sa tšepe sa S235JR se bontša
"S": tšepe e tloaelehileng ea European carbon structural steel;
"235": matla a tlhahiso ke 235, yuniti: MPa;
"JR": tšusumetso ka mocheso o tloaelehileng
3. S235JR seporo sa tšepe se tloaelehileng se tloaelehileng: EN10025 standard
4. Boemo ba ho fana ka poleiti ea tšepe ea S235JR: ho chesa ho chesa, ho phalla ho laoloang, ho tloaeleha, joalo-joalo Boemo ba ho fana ka thepa bo ka boela ba boleloa ho latela litlhoko tsa theknoloji.
5. S235JR tšepe poleiti botenya tataiso ditlhoko tsa tshebetso: Z15, Z25, Z35.
Tlhahlobo ea sebopeho sa lik'hemik'hale sa poleiti ea tšepe ea S235JR
S235JR Sebopeho sa lik'hemik'hale:
S235JR poleiti ea tšepe e nang le carbon content C: ≤ 0.17
S235JR tšepe poleiti silicon dikahare Si: ≤ 0.35
S235JR tšepe poleiti manganese content Mn: ≤ 0,65
Likahare tsa phosphorus tsa S235JR tšepe ea tšepe P: ≤ 0.030
S235JR tšepe poleiti sebabole dikahare S: ≤ 0.030
3, Mechanical thepa ea S235JR tšepe poleiti
Botenya 8-420mm:
Matla a ho hlahisa MPa: ≥ 225
Matla a tenneng MPa: 360 ~ 510
Elongation%: ≥ 18
4, ts'ebetso ea tlhahiso ea tšepe ea S235JR:
Phallo ea ts'ebetso ea tlhahiso: ho qhibilihisa sebōpi sa motlakase → LF/VD sebōpi → ho lahla → ho hloekisa → ho futhumatsa engot → ho futhumatsa poleiti → ho qeta → ho seha sampole → tlhahlobo ea ts'ebetso → sebaka sa polokelo
5, S235JR tšepe poleiti boholo botenya selelekeleng
