Compared with chains manufactured according to GB, DIN, and PN standards, the performance-enhanced C-grade reinforced (>900MPa) and D-grade (>1050 MPa) round link chains have high wear resistance and high strength. The wear resistance and high strength of these products are due to the use of high-quality alloy steel and Ruili's unique production process in the production process. The steel used is a highly optimized special steel. The steel is based on the GBT10560-2008 standard and has trace alloying elements added in accordance with Ruili's technical specifications. The highly optimized steel plus the special heat treatment process ensures that the produced chain can obtain higher and better technical performance and actual working performance. This technology provides the best hardness distribution for each link and provides special hardening for individual links of each grade, that is: the hardness of the arc is high, but the hardness of the straight edge of the chain is lower and has better toughness. Due to the increased tensile strength of the chain, especially the highest grade: D, it is susceptible to application in highly corrosive environments. In these cases, we recommend using our computer-aided design software to analyze and select the most suitable chain for everyone to use.
