According to the type of production, boiler tubes can be divided into seamless steel tubes and welded steel tubes. Boiler tubes are mainly used in pipelines, heating equipment, machinery industry, petroleum geological exploration, chemical industry and other fields. Because of the special purpose of the boiler tubes, the technical parameter requirements of the EN 10025 S355 ml, boiler tubes are also different. Generally speaking, boiler tubes must have pressure resistance, high temperature resistance, oxidation and corrosion resistance, and high tensile strength.

The secondary quenching and low temperature tempering of EN 10025 S355 ml, wear-resistant composite plate is mainly used for important carburized parts with high mechanical properties, especially for coarse grain steel. However, after carburizing, it needs to be heated twice at high temperature to increase the deformation and oxidation decarburization of the workpiece.

ANDRITZ GROUP is the world's leading industrial group, with 29500 employees and more than 280 branches in more than 40 countries. We have cooperated with their Mexico company for many years about S355J2+N steel plates and cutting sectors. The S355J2+N steel plates EN 10025 S355 ml need to cut according to the drawing by standard tolerance, UT, MT and dimension request. The final application of the S355J2+N steel plates and cutting sectors are for assembling hydraulic machine.
