Heat treatment of impact test S355ML

DIN 17100 St37-2 steel plate belongs to the carbon and low alloy high strength steel plate. We can supply the different sizes of impact test S355ML, DIN 17100 St37-2 steel plate. And the rolling size of DIN 17100 St37-2 steel plate is following: the thickness range is 1.2-600mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the DIN 17100 St37-2 steel coil thickness should not exceed 25 mm.

Fake and inferior steel plates are easy to scratch because of the simple equipment of the manufacturers of fake and inferior materials, which are easy to produce burrs and scratch the surface of the steel plate. Deep scratches reduce the strength of the impact test S355ML, steel plate. The surface of the fake and inferior material is prone to cracks, because its billet is adobe, which has many pores. The adobe is subjected to thermal stress during the cooling process, and cracks are generated, and there will be cracks after rolling.

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 impact test S355ML increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of impact test S355ML during tempering, while tempering determines the performance and life of the workpiece.

Application of medium and thick plates: Medium and thick plates are used for construction engineering, machinery manufacturing, shipbuilding, bridge construction, etc. Medium and thick plates impact test S355ML can also be used to manufacture various containers, furnace shells, furnace plates, some parts of tractors and welding components. Medium and thick plates are usually in form of bridges and automobile static steel plates, low alloy steel plates, shipbuilding steel plates, boiler steel plates, pressure vessel steel plates, checkered steel plates, automobile girder steel plates, etc.
