7mm size thickness JIS SM570 plates price

The elongation of low alloy high strength steel is 15% - 23%, and the impact absorption energy is more than 34J at room temperature. The JIS SM570 plates, 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.

Manganese is used to deoxidize and remove sulfur in steel when making steel. It is an beneficial element in JIS SM570 plates steel. Manganese has a strong ability to deoxidize and remove sulfur, it can eliminate or reduce the hot brittleness caused by oxygen and sulfur, and improve the strength and hardness of JIS SM570 plates steel.

From the ship plate to our building materials, steel plate is needed everywhere in our daily life. The quality of JIS SM570 plates, steel plate is also related to each of us. Therefore, the quality of steel plate should be strictly controlled from manufacturer to the user. Once there are quality problems with steel plate, it is very easy to generate major events endangering people's lives.

According to a report by yonhap news agency on April 26, under the impact of COVID - 19 epidemic, the steel industry chain was also affected. Hyundai lost 29.7 billion won. According to the report, the automobile and other downstream steel industry production stoppage directly led to a precipita-like decline in steel demand, is the main reason for the decline in steel enterprise performance of the main reason for hyundai said, hyundai kia motor production extension, by the end of April is expected to reduce production of 500,000 vehicles, as a result, JIS SM570 plates, automotive steel demand will be reduced by 300,000 tons.
