What are the applications of steel plate s235

After extrusion, the steel plate s235 tube shall be removed for sizing. The sizing machine uses a cone-shaped bit to rotate into the steel embryo at high speed to drill holes to form steel pipes. The inner diameter of the steel pipe is determined by the outer diameter length of the drill bit of the sizing machine. After sizing, the steel pipe will enter the cooling tower and be cooled by water spray. After cooling, the steel pipe will be straightened. After straightening, the steel pipe is sent to the metal flaw detector (or hydraulic test) by the conveyor belt for internal flaw detection.

steel plate s235, S460ML-Z35 is a low-alloy high-strength material.S460ML-Z35 chemical composition C ≤0.18, Si≤0.65, Mn ≤1.80, P≤0.03, S≤0.025.S460ML-Z35 mechanical properties: -20℃ impact energy is 27J. Yield strength 275–355 MPa, tensile strength 450–680 MPa.

It is reported that Hoa Phat's current steel plate s235 production capacity is 8 million tons/year. In 2021, the company plans to produce 5 million tons of construction steel and billets, 2.7 million tons of hot-rolled coils, 920,000 tons of steel pipes and 300,000 tons of coated sheets.

The toughness of steel such as steel plate s235 is the ability of steel to absorb energy in the process of plastic deformation and fracture, and also the ability of steel to resist impact load. It is related to and different from the plasticity of steel. It is the comprehensive performance of strength and plasticity. The strength plasticity index of steel is obtained by static tensile test. When these indexes are used to bear the dynamic load structure, there are obvious limitations.
