The BBNSTEEL company has the first-class qualification for steel structure professional contracting, integrating production, design and installation, and can undertake various steel structure projects. The product has a wide surface, flat and smooth surface, and neat trimming. It has users in more than 10 provinces and cities in China and is exported to the United States, Canada, Japan, Europe, Southeast Asia and other countries and regions.

For ZQS700L 1.2mm coil, automobile steel sheet materials, it must have excellent pressure-bearing performance. Automobile steel sheets of substandard quality are prone to fracture problems, which also cause waste and consumption of production materials, and directly increase the production cost of automobiles. Generally, the qualified automobile steel sheets used in automobile manufacturing are high-strength steel plates. The high-quality automobile steel sheets are more durable and improve the quality of the entire automobile.

The elongation of low alloy high strength steel is 15% - 23%, and the impact absorption energy is more than 34J at room temperature. The ZQS700L 1.2mm coil, low alloy high strength steel has good plasticity and impact resistance, which can avoid brittle fracture during impact, and make cold bending and welding easy. In addition, the brittle transition temperature of low alloy high strength steel is low, and the absorbed work value of Grade E steel is not less than 27J at - 40℃. This is of great significance to the engineering components and transportation tools such as vehicles, ships, offshore oil platforms, containers, bridges and so on.

Temperature has a great influence on the strength of the material, ZQS700L 1.2mm coil. When the temperature exceeds a certain value, the strength limit of the steel will be reduced. The higher the temperature, the lower the strength. In addition, the longer the steel is used at high temperature, the lower the strength. Therefore, if the steel works at high temperature for a long time, the instantaneous strength of the steel can not be used as its performance index, nor can the room temperature performance replace the high temperature performance.

20Mn2 steel has medium strength, and the properties of 20Mn2 steel and 20Cr steel are similar. The impact toughness and weldability of 20Mn2 steel at low temperature are better than those of 20Cr steel. The plasticity and machinability of 20Mn2 steel are high during cold deformation. The hardenability of 20Mn2 steel is higher than that of corresponding carbon steel, ZQS700L 1.2mm coil. Chemical composition of 20Mn2 steel: C: 0.17-0.24, Si: 0.17-0.37, Mn: 1.40-1.80. Mechanical properties of 20Mn2 steel: tensile strength ≥ 785 MPa, yield strength ≥ 590 MPa, elongation after fracture ≥ 10%, section expansion rate ≥ 40%, impact absorbed energy ≥ 47J.

The strip steel thickness is generally below 6mm, which is convenient for crimping and processing. You should choose the ZQS700L 1.2mm coil, strip steel specifications according to your own purposes. The specifications and materials used for different purposes are different, so you must confirm it before buying. It is best to ask professionals to give advice before purchasing strip steel, and purchase the specifications and types you need according to the corresponding requirements.

Our company will accept the product quality objection registration record, pass it to the ZQS700L 1.2mm coil production unit and relevant departments, and timely coordinate the supervision of product ZQS700L 1.2mm coil quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
