Is Q235A carbon steel plate sheet or Q235B steel stronger?

Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, Q235A carbon steel plate sheet based on a high starting point and high technology, the company has vigorously developed various steel products Q235A carbon steel plate sheet and deep-processed parts, steel structures, precision castings, seamless pipes.

Compared with other steel plates, the alloy steel plate has outstanding resistance to high and low temperature and climate. In extremely cold or high temperature conditions, the alloy steel plate will not be affected and damaged, and its stability is very good. Of course, compared with ordinary steel plate, alloy steel plate price is higher. Therefore, not all places will adopt alloy steel plate, after all, the price is not cheap, which will affect sales. So, what are the common uses of Q235A carbon steel plate sheet, alloy steel plate?

45# steel is commonly used medium carbon quenched and tempered structural steel. The steel Q235A carbon steel plate sheet is generally cold plastic, annealing and normalizing are slightly better than quenching and tempering, with higher strength and better machinability. After proper heat treatment, 45# carbon steel can certain toughness, plasticity and wear resistance can be obtained. 45# steel normalizing can improve the cutting performance of roughness less than 160HBS.

Modern steel-making steel purification facilities and advanced quality control methods have been perfected. Rolling steel can be produced according to controlled rolling and controlled cooling, normalizing, and quenching and tempering processes to produce σs 390-685Mpa series products. Q235A carbon steel plate sheet, Low alloy high strength structural steel plate has stable quality, good wear resistance and low temperature toughness. It can be widely used in the manufacture of mining machinery, engineering machinery, high-rise buildings and heavy vehicles.

Q235A carbon steel plate sheet, Q690D steel is a high-strength welded structural steel grade. Q the first letter of the Chinese spelling of Qu for the yield strength of steel; 690 represents the yield strength value, the unit is MPa, and D represents the grade of the steel plate; -20 ; common steel plate quality grade steel plates are Q690A, Q690B, Q690C, Q690D, Q690E.
