Q235B Carbon Steel: Mus-Rau qis- Cov Khoom Siv Hluav Taws Xob rau Kev Ua Haujlwm Ntiaj Teb

Raws li lub hauv paus tseem ceeb qis- carbon structural steel raws li Tuam Tshoj tus qauv GB / T 700, Q235B yog lub ntiaj teb nyiam rau nws qhov kev ua tau zoo thiab tus nqi- ua tau zoo. Nws lub npe qhia txog lub zog tseem ceeb: "Q" rau lub zog tawm los, "235" rau qhov tsawg kawg nkaus 235 MPa yield zog, thiab "B" rau kev xeem dhau 20℃cuam tshuam -zoo tagnrho rau ambient-kub tej yaam num.

 

Boasting zoo weldability, zoo formability, thiab txhim khu kev qha mechanics, Q235B (0.14–0.22% carbon cov ntsiab lus) yog ib qho yooj yim mus txiav, khoov, thiab weld, suiting complex los yog nyob rau hauv - site los ua ke. Nrog 375-500 MPa tensile lub zog, nws sib npaug durability thiab workability, tsis txhob raug nqi ntau dhau.

 

Nws ci thoob plaws kev lag luam: kev tsim kho (steel thav duab, txuas hniav), kev tsim khoom (cov khoom siv, cov khoom siv), kev thauj mus los (tsheb thav duab, trailer undercarriages), thiab txawm tias cov khoom siv (steel rooj tog). Ua raws li ASTM A36 thiab EN S235JR, nws koom ua ke rau hauv cov khoom siv thoob ntiaj teb.

Tus nqi -ntau npaum vs. alloy steels, Q235B muaj kev hloov kho (qhov loj me, txheej txheej) thiab rov ua dua tshiab, ua raws li cov hom phiaj kev ruaj khov- ua rau nws yog qhov kev xaiv zoo tshaj plaws rau ntau yam haujlwm.
