High strength FB2 steel thickness range for tube

Thin FB2 steel thickness range, steel plate is mainly used in automobile industry, aviation industry, enamel industry, electrical industry, machinery industry and other departments. The main requirement of thin steel plate is to facilitate bending and forming. The thinner the steel plate is, the easier it is to bend. The common specifications of thin steel plate include thickness less than 4mm, width about 500-1500mm and length about 1.5-4m.

Focusing on the energy conservation and emission reduction objectives proposed by the municipal government, the company gives full play to the advantages of FB2 steel thickness range circular economy formed after the comprehensive completion and operation, and vigorously promotes the implementation of energy conservation objectives. Through measures such as energy saving, technological innovation and FB2 steel thickness range management strengthening, the energy saving target of annual reduction of added value energy consumption by 7%. It has made great contribution to energy saving of over completion.

In the second step of hot rolling process, different finished mills are used to roll billets or continuous casting billets into finished steel of proper shape and size. This FB2 steel thickness range production process is called finished product production, which is generally divided into two stages of rough rolling and finish rolling. In the roughing stage, a large amount of reduction (reduction per pass) is adopted to reduce the number of passes and improve the output; after roughing, the finishing stage is entered, and the finishing is carried out with a small amount of reduction to achieve a good surface and accurate FB2 steel thickness range size.

The final heat treatment of quenched and tempered alloy steel, FB2 steel thickness range is quenching and high temperature tempering. The hardenability of quenched and tempered alloy steel is high, and oil is generally used. When the hardenability is very high, it can even be air cooled, which can reduce the defects of heat treatment. The final properties of quenched and tempered alloy steel depend on tempering temperature. Generally, it is tempered at 500 ℃ - 650 ℃. The required properties can be obtained by selecting tempering temperature. In order to prevent the second kind of temper brittleness, fast cooling (water cooling or oil cooling) after tempering is beneficial to the improvement of toughness.

Respect customers and treat each other sincerely. Customers are always right. Always remember that the user is the God of the enterprise, respect the customer, and accept the customer's opinion modestly is the guarantee of the long-term development of the enterprise. Adhere to this concept, so that the service and the product are the same, long-term.
