What data needs to be confirmed for EN 10025-6 high strength steel 1.8906 cutting

When the thickness ≤16mm, the yield strength of TMCP Q460MC steel plate is ≥460 Mpa, and the tensile strength is 540-720 Mpa. TMCP Q460MC steel plate is used as high strength steel structural parts for engineering and general structures with impact performance requirements at low temperature. EN 10025-6 high strength steel 1.8906, Q460MC steel plate is mainly used for manufacturing bridges, ships, vehicles, boilers, high pressure vessels, oil and gas pipelines, large steel structures, etc.

The effect of nitrogen (N) on the properties of EN 10025-6 high strength steel 1.8906 and so on steel is similar to that of carbon and phosphorus. With the increase of nitrogen content, the strength of steel can be significantly improved, especially the plasticity, especially toughness, and the weldability will be decreased, and the cold brittleness will be intensified. At the same time, aging tendency, cold brittleness and hot brittleness will be increased, which will damage the weldability and cold bending property of steel. Therefore, the nitrogen content in EN 10025-6 high strength steel 1.8906 and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.

The heat treatment process can significantly improve the physical properties of steel, improve the compressive strength, ductility and service life of parts, and improve the hardness and wear resistance. Therefore, critical equipment parts and special tools must be quenched and tempered. The quenching and tempering treatment can also improve the production and processing performance of the EN 10025-6 high strength steel 1.8906 product workpiece, thereby improving the production efficiency and production processing quality.

Seamless steel pipe refers to the steel pipe made of a whole piece of metal without joints on the surface. According to the production method, it can be divided into hot rolling tube, cold rolling tube, cold drawing tube, EN 10025-6 high strength steel 1.8906, extrusion tube and spinning tube. According to the shape of the section, it can be divided into two types: circular and irregular. The seamless tube has a maximum diameter of 650 mm (expanding tube) and a minimum diameter of 0.3 mm (capillary tube), which can be divided into thick walled tube and thin walled tube according to the thickness.
