EN 10297-1 Seamless Tube For machining hollow bars
Hollow bars standard EN 10297-1 specification for seamless steel tubes (hollow bars) for machining and engineering purposes, the grades E235, E355, D470, C22E and C45E are mainly used in mechanical engineering, crane construction and conveyor technology, load-bearing Processing in machine parts factories and cylinder manufacturing
EN 10297-1 is the European standard for "Seamless steel tubes for mechanical and general engineering purposes". This standard covers seamless steel pipes for mechanical and general engineering applications.
EN 10297-1 Hollow Bar/Seamless Steel Pipe:
High-quality seamless manufacturing: EN 10297-1 standard requires seamless manufacturing. This means that the manufacturing process of seamless steel pipes does not include welding, thus eliminating the weaknesses of welded joints. Seamless manufacturing ensures overall performance and reliability of the tube.
High strength and wear resistance: The material of EN 10297-1 seamless steel pipe has good mechanical properties, including high strength and wear resistance
Good dimensional control: Dimensions such as outer diameter, wall thickness and length have high accuracy and consistency, ensuring their adaptability and interchangeability.
Heat treatment capability: It can be heat treated to improve its mechanical properties. The heat treatment process can adjust the hardness, strength and toughness of the pipe to meet the requirements of specific applications.
