White spots on q235b hot rolled carbon steel are not allowed

The size of the crystal grains can be controlled by the annealing conditions of the q235b hot rolled carbon steel steel sheet, and the boiling steel sheet is more likely to change greatly. Especially in order to improve the formability of boiling q235b hot rolled carbon steel steel and the processability of enamel products (such as not easy to foam), it is decarburized and annealed to make cold-rolled steel sheets with coarser grains and soft texture. However, if the crystal grains are too coarse, the forming limit of spinning may be reduced.

We can process the steel materials according to your drawing. Or if you can not make drawing, please send us q235b hot rolled carbon steel specific data and requirements, our technical department can make design and drawing for you, and then confirm with your technician or engineer. If all is OK, our processing center will process the steel materials according to the drawing. So no matter what size and shapes you need, we can meet demands at the most time.

The carbon and low alloy steel plates are our main products. Our main conducted standards for carbon and low alloy steel plates are (ASME) ASTM (S)A36, (S)A283, q235b hot rolled carbon steel, (S)A572, (S)A573, (S)A633, (S)A709, EN10025-2, EN10025-3, EN10025-4, EN10025-6, JIS G3101, JIS G3106, DIN 17100, DIN 17102, etc. Our typical carbon and low alloy steel grades are (S)A36, (S)A283 grade C, (S)A572 grade 50, S235JR, S355JR, S355J2, SS400, SM570, ST37-2, ST52-3, Q235B, q235b hot rolled carbon steel, Q345B, etc.
