SAE certification
American Society of Automotive Engineers (SAE) was founded in 1905, is the world's largest automotive engineering academic organization. The research object is the car, truck and engineering vehicle, aircraft, engine, materials and manufacturing, etc.. The standards developed by SAE are authoritative and widely used in the automotive industry and other industries, and a considerable part of the United States national standards are adopted.
SAE motor vehicle standard is the technical standard of the locomotive industry. The American Society of Automotive Engineers (SAE) certification: the market for the sale of auto parts (SAE certification) standards, these parts are not as a supplier of bulk sales.
SAE8620 corresponds to the national standard 20CrNiMo of this kind of steels suitable for machining gear, good hardenability.
