Hot rolled polishing Q235A carbon steel plate sheet

The company was established in 2000, covering an area of more than 4,500 acres. It has fixed assets of 200 million yuan, and employs more than 1,200 people. It has now formed coking, sintering, white ash, pellets, ironmaking, Q235A carbon steel plate sheet steelmaking, steel rolling, oxygen production, gas and waste heat The complete circular economy industrial chain including power generation, comprehensive utilization of slag, soot and dust treatment, sewage treatment and recycling, etc. It mainly produces hot-rolled steel plates and Q235A carbon steel plate sheet carbon structural steels, high-quality carbon structural steels, low-alloy high-strength steels, medium and wide-band steels for cold-rolled stamping, and hot-rolled coils.

Generally, when we distinguish and judge whether it is a high-quality Q235A carbon steel plate sheet, automotive steel sheet manufacturer, the manufacturer's corporate brand and the reputation of the Q235A carbon steel plate sheet, automotive steel sheet are good proofs. We can check the sales of automotive steel sheets manufacturers and the comments of buyers on the products and so on aspects about the automotive steel sheet manufacturer. The ones with more sales and higher praise rate are naturally better manufacturers. These can be used as some reference opinions for us to choose automobile steel sheet manufacturers.

With the development of science, technology and industry, higher requirements are put forward for steel materials, such as higher strength, resistance to high temperature, high pressure, low temperature, corrosion resistance, abrasion, and other special physical and chemical properties. Q235A carbon steel plate sheet, carbon steel can no longer fully meet the requirements, so alloy steel plates appeared. Improving the strength of steel is one of the main purposes of adding alloying elements.

Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the Q235A carbon steel plate sheet steel plate, then wipes the excess penetrant with the cleaning solution, and then smears the developer. The penetrant remaining in the defect is adsorbed by the developing material, so as to observe the shape of the defect and determine the type of defect. This Q235A carbon steel plate sheet method requires multiple wipes before and after the inspection, the process is more cumbersome, and can not detect internal defects and rough and dirty steel plates.

20 # material is a high-quality low-carbon carbon steel, cold-extruded, carburized and hardened steel. Q235A carbon steel plate sheet, 20 # material has low strength, good toughness, plasticity and good weldability. Chemical composition of 20 # round steel bar: C: 0.17 ~ 0.23, Si: 0.17 ~ 0.37, Mn: 0.35 ~ 0.65, S: ≤0.035, P: ≤0.035, Cr: ≤0.25, Ni: ≤0.30, Cu: ≤0.25. 20# carbon steel mechanical properties: Shear strength 275 ~ 392MPa, Tensile strength is 253 ~ 500MPa, elongation min. 25%.
