The reasons for unqualified impact performance of medium and thick plates can be attributed to multiple aspects, mainly including raw material problems, production process problems and problems in the quality inspection process. The following is a detailed analysis of these reasons: If the composition of the slab used for rolling medium and thick plates is unreasonable, such as too much sulfur, phosphorus and other impurities in the molten steel, these impurities will affect the purity and organizational structure of the steel plate, thereby reducing its impact performance. Insufficient or excessive content of alloying elements in stainless steel may also cause the impact performance of the steel plate to be substandard. During the smelting and rolling process, if the control is not proper, segregation and banded structure may appear in the steel. These organizational defects will reduce the impact toughness of the steel plate, especially under low temperature conditions. In the production process, the setting of the heating temperature of the slab heating has an important influence on the performance of the medium and thick plate. If the heating temperature is too low, the steel plate may be uneven in organization and affect its impact toughness; if the heating temperature is...

Tensile properties are one of the main performance indicators of metal materials. Among them, parameters such as yield and tensile strength are the most representative mechanical performance indicators of metal materials, and are also important bases for stress calculation in engineering design and mechanical design.
The treatment process of forming an extremely thin and strong protective layer on the surface of stainless steel through nano-coating technology can not only achieve the anti-fingerprint effect of the stainless steel surface, but also improve the corrosion resistance.
