Wax ku saabsan S235JR

S235JR waa bir qaabdhismeed aan dawac ahayn oo Yurub ah, oo u dhiganta heerka qaranka Q235B, kaas oo ah bir qaab dhismeedka kaarboon oo leh kaarboon yar.Waxaa loo isticmaalaa alxanka, bolting iyo dhismayaasha jeexjeexa.

Birta qaab dhismeedka kaarboon waa nooc ka mid ah birta kaarboonka.Waxa ku jira kaarboonku waa 0.05% ~ 0.70%, qaarna waxay noqon karaan ilaa 0.90%.Waxa loo qaybin karaa birta qaab dhismeedka kaarboon ee caadiga ah iyo birta qaab dhismeedka kaarboon oo tayo sare leh.Waxaa si weyn loogu isticmaalaa tareenka, buundada, mashaariicda dhismaha ee kala duwan, soo saarista qaybo bir ah oo kala duwan oo xambaarsan culeys joogto ah, qaybo farsamo oo aan muhiim ahayn iyo alxanka guud ee aan u baahnayn daaweynta kulaylka.

Heerka saxanka birta ee S235JR ayaa tilmaamaya

"S": birta qaab dhismeedka kaarboon caadiga ah ee Yurub;

“235″: xoog waxsoosaarku waa 235, unugga: MPa;

"JR": saamaynta heerkulka caadiga ah

3. S235JR saxan bir ah heerka fulinta: heerka EN10025

4. Xaaladda bixinta S235JR saxan bir ah: rogid kulul, rogid la xakameeyey, caadi ahaan, iwm. Xaaladda gaarsiinta ayaa sidoo kale lagu qeexi karaa iyadoo loo eegayo shuruudaha farsamada.

5. S235JR saxan dhumucdiisuna waxay jihada shuruudaha waxqabadka: Z15, Z25, Z35.

Kala soocidda dusha sare
Dusha caadiga ah (FA)
Dusha sare ee la qaaday ayaa loo ogol yahay in ay leedahay cillado yaryar iyo kuwo maxalli ah sida godadka, jeexjeexyada, xagashada, iwm. kuwaas oo qoto dheer (ama dhererka) aanu ka badnayn kala badh dulqaadka dhumucda birta, laakiin dhumucda ugu yar ee la ogol yahay ee saxanka birta iyo xadhig bir ah waa in la damaanad qaadaa.
Dusha sare (FB)
Dusha sare ee wax-soo-saarka ayaa loo oggol yahay inay yeelato cillado maxalli ah oo aan saameyn ku yeelanayn qaab-dhismeedka, sida xagashada yaryar, jeexjeexyada yaryar, godadka yar yar, calamadaha rullaluistuyada yar iyo kala duwanaanta midabka.

Isticmaalka alaabta
Waxaa inta badan loo isticmaalaa dhismaha, buundada, markabka, qaybaha dhismaha baabuurta, soo saarista qalabyo kala duwan, qalabka goynta, caaryada iyo qalabka cabbiraadda.
