The toughness of steel such as P265GH plate 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.

The selection principle of steel plate for high-rise building is: it can not only make the structure safe and reliable, but also can save steel and reduce the cost. Different use conditions should have different quality requirements. In terms of the mechanical properties of steel such as p265gh plate, yield point, tensile strength, elongation, cold bending property, impact toughness etc. are the indicators to measure the quality of steel. In the design of steel structure, the appropriate steel should be selected according to the characteristics of the structure. The selection of steel is not only an economic problem, but also related to the safety and service life of the structure.

It is reported that during the period from the end of 2018 to the first quarter of 2019, some Japanese long process steel mills encountered a series of production line equipment failures, resulting in the overall output decline. Japanese p265gh plate steel mills must give priority to domestic customers, so the export volume in the first half of last year was relatively small. Meanwhile, in the first half of the year, Japan's imports of general p265gh plate steel were about 2.079 million tons, down 16.4% year-on-year; imports of special steel were about 332000 tons, down 14.2% year-on-year.

Chromium element (Cr element) can improve the strength and hardness of p265gh plate, carbon steel in rolling state, reduce elongation and area reduction. When the chromium content is more than 15%, the strength and hardness will decrease, while the elongation and reduction of area will increase correspondingly. It is easy to obtain high surface processing quality for steel parts containing chromium after grinding. The main function of chromium element (Cr element) in quenched and tempered steel structure is to improve hardenability, so that the steel has better comprehensive mechanical properties after quenching and tempering.
