The products are widely used in petroleum, chemical, electric, boiler, ship, machinery and other industries, and have been sold all over the country. Many A572 Gr 42 carbon steel plate sheet products have been exported to the Middle East, India, Southeast Asia and Europe and America.

A572 Gr 42 carbon steel plate sheet, 45Mn2 steel is a kind of alloy structural steel. 45Mn2 steel is made of high-quality carbon structural steel with proper addition of manganese. 45Mn2 steel belongs to the medium carbon quenched and tempered steel in alloy structural steel. The parts made with 45Mn2 steel can obtain high strength and good toughness after quenching and tempering at high temperature. That is to say, 45Mn2 steel has good comprehensive mechanical properties and is often used to manufacture shafts, connecting rods, fasteners which bear large loads.

The cold rolled sheet does not produce scale because it is rolled at room temperature. Therefore, the surface quality of cold plate is good and the dimension precision is high. In addition, the mechanical and technological properties of cold rolled coil are better than that of hot-rolled steel sheet. In many fields, especially in the field of home appliance manufacturing, it has gradually replaced hot-rolled steel sheet, A572 Gr 42 carbon steel plate sheet.

The final heat treatment of quenched and tempered alloy steel, A572 Gr 42 carbon steel plate sheet 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.
