ATC600 Material Composition

ATCORP, ATC-600 Monometal hardened steel bearing, consists SPCC, ST12 or other thin-walled low carbon steel with steel , Made by stamping or roll forming process and then after carbonitriding heat treatment. The wear resistant layer having high hardness is formed during this process.ST12 is generally preferred over SPCC due to its higher strength and suitability for applications requiring wear resistance and load-bearing capacity. ST12, a low-carbon steel, can be through-hardened or case-hardened, making it a versatile choice for various bushing applications. Not ideal for high-temperature applications, as its properties can degrade above 300°C.SPCC is also a cold-rolled steel, but it's generally used for general purpose applications. While it offers good strength and formability, it may not be as wear-resistant as ST12, especially in high-load or high-friction applications. Suitable for less demanding applications where wear and load requirements are not as critical. SPCC is susceptible to rust and requires post-treatments like painting or plating to prevent corrosion
