Europeean between EN 10025-6 S500QL1 high strength steel for hot rolled

20Mn2 steel is used to manufacture carburized parts with low requirements on the surface and core, and with a cross-sectional diameter of less than 50mm, such as carburized pinions, small shafts, and low-demand pistons instead of 20Cr steel in the manufacture of automobiles, tractors and machine tools Pins, cross pin heads, diesel engine sleeves, valve jacks, gearbox levers, steel sleeves, etc. In addition, this kind of steel can also be used to make riveting weldments, screws, nuts, etc. under hot rolling and normalizing conditions.

In order to prevent the deformation of EN 10025-6 S500QL1 high strength steel, wear-resistant composite plate during preheating, the steel plate with good quality should be selected first. The steel plate with serious carbide segregation should be reasonably cast and heat treated by quenching and tempering. For the large and non cast wear-resistant composite plate, the solution double refining heat treatment can be carried out. At the same time, the heating temperature should be reasonably selected and the heating speed should be controlled.

Flame cutting is a common hot cutting method in modern iron and steel industry. It is also a very important part in the process of iron and EN 10025-6 S500QL1 high strength steel steel processing. Flame cutting can cut very thick carbon steel, its cutting range is very wide, can cut 6mm-200mm thick steel plate. In cutting thick and EN 10025-6 S500QL1 high strength steel medium plates, flame cutting plays an important role. And with its price advantage, flame cutting has always occupied a certain market share in thin plate cutting also.
