Reaguan Steel Shot has formed a complete set of quality control system through the advanced steel-making process and sampling test of each production process to strictly control the quality. Add rare metals Mn, Ni, Gr, etc. to increase the service life and impact resistance of steel shot. The quality of steel shot conforms to relevant domestic and foreign standards such as American SAE, ISO, GB (2008.9.1 implementation), and YB.
Process flow: smelting (adding rare metals) → centrifugal atomization into pellets → drying → coarse sieve quenching → round selection → fine sieve tempering → packaging. After the steel shot is quenched and tempered, the compactness can be improved, the metallographic structure of the steel shot can be improved, and a uniform tempered martensite can be formed.
Metallographic structure: Reaguan steel shot is added with rare metals after quenching, tempering and other heat treatment processes to obtain uniform tempered martensite, with fine and uniform dispersed carbides, which reduces the fracture rate of steel shot. In some steel shot manufacturers, although the products have martensite, the distribution of carbides is segregated at the network or dendritic grain boundaries. This kind of steel shot is easily broken and affects the service life.
Fatigue life of products: The quality of steel shot and steel grit depends on whether the production process is reasonable, whether rare metals are added in the steelmaking process, and the tempering temperature is consistent with the required hardness, which determines the length of the fatigue life. Another point is that the steel shot is not easy to break. Wear and tear of equipment wearing parts is reduced.
The fatigue Owen life of Lubei steel shot reaches 2800 to 3200 Times.
