Product introduction | ||||
Special-shaped seamless steel tube is the general name of seamless steel tube with other cross-sectional shapes except circular tube. According to the different cross-sectional shapes and sizes of steel pipes, it can be divided into special-shaped seamless steel pipes with equal wall thickness (code D), special-shaped seamless steel pipes with unequal wall thickness (code BD) and special-shaped seamless steel pipes with variable diameter (code BJ). | ||||
Properties of special-shaped steel pipes; | "1. Performance index of special-shaped steel pipe-plasticity 2. Performance index of special-shaped steel pipe-hardness 3. Performance index of special-shaped steel pipe-fatigue 4. Performance index of special-shaped steel pipe-impact toughness 5. Performance index of special-shaped steel pipe-strength " |
|||
The purpose of special-shaped steel pipe: | Special-shaped seamless steel pipes are widely used in various structural parts, tools and mechanical parts. | |||
Special-shaped steel pipes are divided into: | Special-shaped steel pipes such as external hexagonal internal circular steel pipe, external hexagonal steel pipe, internal and external hexagonal steel pipe, flat oval steel pipe, oval steel pipe, triangular pipe, L-shaped steel pipe, octagonal pipe, mushroom-shaped pipe, bread-shaped pipe, D-shaped pipe, concave pipe, convex pipe, umbrella-shaped pipe, P-shaped pipe and ingot-shaped pipe are produced according to users' needs. | |||

Characteristics and application: This steel series is imported from American AISI/SAE standard steel grade 8720. Its hardenability is similar to that of 20CrNi steel, and its strength is higher than that of 20CrNi steel. Used to manufacture gears for engines and transmission systems of small and medium-sized cars and tractors; It can also replace 12CrNi3 to manufacture carburized steel and carbonitriding parts with higher requirements for central performance, such as the jaw and cone body of cone bits for oil drilling and metallurgical mining.
