Chromium element (Cr element) can improve the strength and hardness of EN standard P295GH sheet, carbon steel in rolling state, reduce elongation and area reduction. When the chromium content is more than 15%, the strength and hardness will decrease, while the elongation and reduction of area will increase correspondingly. It is easy to obtain high surface processing quality for steel parts containing chromium after grinding. The main function of chromium element (Cr element) in quenched and tempered steel structure is to improve hardenability, so that the steel has better comprehensive mechanical properties after quenching and tempering.

Thin steel plate is a kind of steel plate material that is thinner in thickness. Generally, steel plate with thickness less than or equal to 4mm is called thin steel plate. As we all know, the steel products we usually see are also divided into different thicknesses. The strength, performance and scope of application of different thickness steel plates, EN standard p295gh sheet are also different. Today, we will talk about some related knowledge of thin steel plates, and take you to understand the characteristics and uses of thin steel plates.

The head of the National Development and Reform Commission, He Lifeng, chaired a special meeting of the Office of the Leading Group for the Development of the Yangtze River Economic Belt. The meeting emphasized that the Yangtze River Economic Belt is the center of gravity and vitality of China's economy, and is of great significance to the overall economic and social development of the country. At present, we must focus on four tasks. The first is to make every effort to resume work and achieve production. The second is to make every effort to promote ecological environmental protection and restoration. The third is to strengthen project reserve work. The fourth is to improve the planning guarantee system.

pressure vessel plates EN standard p295gh sheet are used to manufacture pressure vessel equipment in petrochemical, gas separation and gas storage and transportation equipment. It is required to have sufficient strength and toughness, good welding performance and hot and cold processing performance. The general heat treatment of Q345R plate is hot rolling, controlled rolling, normalizing. The impact temperature is normal temperature, 0 ° C, -20.
