The composition and properties of s235jr hot rolled steel plate

SM400 steel plate is a Japanese grade. s235jr hot rolled steel plate, SM400 steel is a carbon structural steel plate for engineering structure and is also used in welding engineering. SM400 steel plate is widely used in aerospace, electric power, petrochemical, shipbuilding, machinery, electronics, environmental protection and other industries.

Rolled sheet is a very common material in industrial construction. Rolled sheet at room temperature is cold-rolled sheet, and cold-rolled sheet is the rolling of hot-rolled coils below the recrystallization temperature. The hot-rolled sheet is rolled above the recrystallization temperature. So what is the difference between s235jr hot rolled steel plate, hot rolled sheet and cold rolled sheet?

Strip steel is mainly used for the manufacture of welded pipes, clamps, washers, spring blades, saw blades, blades and other fields, so the s235jr hot rolled steel plate, strip steel specifications are also relatively standardized. First, the strip width should be within 1300mm, if it is too wide, it will become a steel plate, and the machining is not allowed to be too wide, otherwise it will fail. Second, the strip steel length is not limited, and the strip steel can be coiled together after bending, reducing most of the space.

On March 10, the price of 14-20mm on the Shanghai medium plate: 4960 yuan/ton, down 40 from yesterday. The price of 14-20 mm Q235C carbon structural steel size: 4970 yuan/ton, down 30 from yesterday. The price of 14-20 Q235D carbon structural steel medium plates: 4970 yuan/ton, down 20 from yesterday.
