1.1 This specification covers five grades of high-strength low-alloy structural steel shapes, plates, sheet piling, and bars. Grades 42 , 50 , and 55  are intended for riveted, bolted, or welded structures. Grades 60  and 65  are intended for riveted or bolted construction of bridges, or for riveted, bolted, or welded construction in other applications.
ASTM/SUS/En/Uns Cold-Drawingsteel Bar (Q235 20# Q195 In the era of global economy, we insist on the excellent quality of all products and continue to develop diversified new series of ASTM/SUS/En/Uns Cold-Drawingsteel Bar (Q235 20# Q195 Q345 Round bar, Hex bar, Square Bar) in order to make the enterprise sustainable.
Carbon quantum dots (CQDs) modified TiO2 nanorods Nov 01, 2020 · A new photoanode of Al 2 O 3 anchored carbon quantum dots/TiO 2 nanorods (Al/C/TNRs) was constructed for efficient photocathodic protection of Q235 carbon steel (CS) by hydrothermal treatment and ALD process. The Al/C/TNRs photoanode achieved a photocurrent density of 2.28 mA/cm 2 under simulated sunlight (AM 1.5 G), and could maintain for 7 days nearly without decay.
