The quality of A514 grade C alloy steel plate shall not only meet the requirements of the standard, but also be higher or stricter than the product characteristics specified in the standard, including chemical composition, structure, physical properties, chemical properties and other requirements of A514 grade C alloy steel plate buyer, such as packaging, delivery time, etc.. On the basis of the quality of A514 grade C alloy steel plate in line with the corresponding standards, some buyers will put forward specific requirements according to their own use requirements, which is called technical agreement. That is, some specific factors should be met according to the buyer's requirements. These requirements may be the control of chemical element content of A514 grade C alloy steel plate and certain performance limit of A514 grade C alloy steel plate, etc.
As a common steel plate in the steel market, A514 grade C alloy steel plate, manganese steel plate has the following characteristics. First, good toughness, stretching and crimping can be done well. Second, the bearing strength of manganese steel plate is good and it can bear a lot of gravity. Third, the A514 grade C alloy steel plate, manganese steel plate is easy to weld, easy to process finished products, and its price is relatively low. Fourth, manganese steel plate has good corrosion resistance, and long service life. Fifth, the manganese steel plate has good mechanical properties, low temperature performance, good plasticity and weldability.
Quenching is a heat treatment process in which steel parts are heated to above the critical temperature, and after proper heat preservation, the parts are quickly cooled to room temperature in water or oil, so that martensite transformation occurs. The hardness of the quenched A514 grade C alloy steel plate increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of A514 grade C alloy steel plate during tempering, while tempering determines the performance and life of the workpiece.
