Three ways of cutting S460QL equivalent grade

The toughness of steel such as S460QL equivalent grade is the ability of steel to absorb energy in the process of plastic deformation and fracture, and also the ability of steel to resist impact load. It is related to and different from the plasticity of steel. It is the comprehensive performance of strength and plasticity. The strength plasticity index of steel is obtained by static tensile test. When these indexes are used to bear the dynamic load structure, there are obvious limitations.

BBN STEEL is an agreement direct selling agent of Wuyang Iron and Steel Company, which mainly deals in medium and extra wide and extra thick steel plates. There are more than 8,000 tons of steel S460QL equivalent grade plates of various specifications for customers to choose. The company's steel plate processing plant can cut semi-finished products and special-shaped parts according to user requirements, and can also transport on behalf of office roads, railways and shipping.

S355J2 steel plate rolling process is controlled rolling process.
In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the S460QL equivalent grade rolling speed is 1.6-2.0m/s, the single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.

With equipment, technology, production technology, quality supervision and other leading advantages, we are leading in the production of all kinds of high-quality, high-tech medium, extra thick, extra wide steel plate S460QL equivalent grade shaped parts. The cutting surface is smooth and clean, the cutting edge is neat, without secondary processing by users, and it can be installed and used directly according to the technical dimensions, with the characteristics of high coincidence rate of positive and negative tolerance and excellent quality. The processed steel products are mainly used in heavy machinery and equipment.
