According to the guarantee conditions of delivery, China and some countries divide the ordinary carbon steel into three categories: Class A steel, which only guarantees the mechanical properties, not the chemical compositions； Class B steel, which only guarantees the chemical compositions, not the mechanical properties; special steel (Class C steel), which not only guarantees the chemical compositions, but also the mechanical properties. Class C steel EN 10149-2 steel grade S420MC is often used to manufacture important structural parts. Density of ordinary carbon steel: 7.85 g / cm3.

en 10149-2 steel grade s420mc, Strip steel has obvious characteristics. First, it is thin and easy to bend, convenient for logistics and transportation, and saves logistics costs. Second, the surface quality of strip steel is good. Third, the strip steel is easy to process, and it can be processed only by straightening the bent part. Fourth, the strip steel has high precision and it is a good raw material for processing blades and saw blades. Strip steel is widely used in the manufacture of welded pipes, clamps, washers, spring blades, saw blades and other fields.

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 en 10149-2 steel grade s420mc increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of en 10149-2 steel grade s420mc during tempering, while tempering determines the performance and life of the workpiece.
