In recent years, with the economic growth and the improvement of people's living standards, the good comprehensive performance of stainless steel and the advantages of durability, beauty, long service life and high cost-effectiveness have been recognized by people, and the stainless steel decoration industry has developed rapidly. It is widely used in the engineering of high-level hotels, clubs, KTV and other high-level places, and stainless steel decoration has become one of the important decoration materials today. Stainless steel decoration is a material that integrates environmental protection, craftsmanship, color and aesthetics, thus enriching the decoration grade and aesthetic awareness of people's living space.

According to 《GB/T40356-2021 Kitchen Knives》, the hardness of the stainless steel blade should not be less than 50HRC. EngineerWu introduced that for the case where the overall hardness of the tool is higher than 50HRC, the higher the hardness, the lower the relative toughness, and the more "brittle" it can be. The toughness mentioned here mainly refers to the impact resistance of the material. If the instantaneous impact load exceeds the impact resistance range of the material, the risk of material fracture is greatly increased."Practice has proved that as long as the stainless steel material is properly selected and maintained, it will have the same life as the building structure. Therefore, stainless steel is an attractive, low-cost, high-yield, and environmentally friendly choice for any design requiring long life.

Stainless steel has been widely used in decorative engineering due to its excellent corrosion resistance, beautiful appearance and long service life. In recent years, stainless steel has been increasingly used in large buildings and street decorations that constitute urban three-dimensional space, making stainless steel an indispensable material for urban three-dimensional landscape paintings.
