Q235 steel plate iyo Q345 steel plate badanaa kale eka soo muuji. Kala iyo midabka midabka steelka lama tixgeli karo, laakiin waxaa ka soo jira fududka isdhaafka ka dib marka steelka la gudubo. Badanaa, waddoonka waa red oo dhaaf ah marka la isdhaafayo. Hadii la isdhaafayo, laya soo saaray oxida oo ka qodday oo ay noqon karto midabka qalac.
Q345 waxaa loola yaqaanayaa si loo sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la sameyo in la same......
Qeybta awooda, waxaa jira toosin kooban:
A.
- Dhulka, waxaa laga eegi karaa noocyada laba ee xawaaraha iyadoo la isticmaalayo tubaabka. Tusaale ahaan, waxaa tubaabkii E43 la isticmaala waxaa la tubaabi jiray laba qaybo oo dherka joogto, ka dibna waxaa la tali karaa jiid. Noocyada laba ee dherka waxaa laga eegi karaa iyadoo la tixgaliyo dhibaatooyinka.
- Dhulka sidoo kale waxaa laga eegi karaa noocyada laba iyadoo la isticmaalayo qalabka xidhka. Markii la xidho dherka Q235 iyadoo la isticmaalayo qalabka xidhka, calaamadaha ayaa muuqdaa in ay yihiin jajab u dhaqaaqda iyo midho dheer. Haddii dherka Q345 ayaa calaamadaha ay yihiin laba jibba iyo midho qumman.
- Iyadoo la rabbiyo ilayada labada dherka, labada nooc ee dherka waxaa laga eegi karaa. Guud ahaan, wadaha Q345 ayaa midho buu qabaa.
B.
- Iyadoo la rabbiyo midhaha dherka, waxaa laga eegi karaa noocyada Q235 iyo Q345: midhaha Q235 ayaa midho xaduud buu qabaa, Oo Q345 waa midho faro (tan waxaa loo yaqaan dherka markii la soo galo dhulka, laakiin sanam laga eegi karo dhamaadooda).
- Qaabta ugu muhiimsan ee falcelinta xawaaraha waa tijaabada kiimikada. Wuxuu ka yartahay Q235 iyo Q345 oo leh kiimikada la itilmaansanayd, iyo kiimikada la itilmaansanayd. (Waa hab farxad baa ka sameeya).
- Si ay uga saameyn karaan Q235 iyo Q345 xawaaraha ugu dhoweynta: xidha laba qaybo oo dhaaf ah oo aan la garanayn iyo u dhow inuu isticmaala barashada dhowga ah. Haddii ay jiraan xidid la midka wadaha, waxaa la isku dayaa inay tahay nooca Q345. (Waa xorriyada ammaanka ah).
