The trampoline column is fully compliant with the HT250's chemical composition standards and standards for mechanical performance testing.
The casting is a metal molded object obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injecting, inhaling or other casting method, and after cooling, after falling sand, cleaning and then Processing, etc., the quality of the obtained castings with certain shape, size and performance mainly includes appearance quality, intrinsic quality and quality of use. Appearance quality refers to the surface roughness, surface defects, dimensional deviation, shape deviation and weight deviation of the casting; the intrinsic quality mainly refers to the chemical composition, physical properties, mechanical properties, metallographic structure of the casting, and the holes, cracks, inclusions existing in the casting. Segregation and other conditions; the use of quality refers to the working durability of the casting under different conditions, including wear resistance, corrosion resistance, chilling heat, fatigue, shock absorption and other properties as well as machinability, weldability and other process properties.
