EN 10294 Hollow bars Machined hollow bars E355, E420J2, E470, E590K2
Hollow bar, also known as seamless mechanical pipe, is a steel bar with a hollow section
The hollow bars produced by EDEST are produced strictly in accordance with EN10294-1 standards.
Hollow bars are manufactured from seamless steel tubes, which means
they are produced without any welded joints. They have a uniform
cross-section and a hollow interior, usually round or oval in
shape.
Outside diameter (OD) and inside diameter (ID) dimensions can vary
based on specific requirements.
Hollow rods are usually made from low alloy steel or carbon steel
Our stock grades: E355, E420J2, E470, E590K2,
EDEST's hollow bars offer optimal strength, toughness and
workability while meeting the requirements of mechanical
applications
Mechanical properties: Hollow rods are known for their excellent mechanical properties, including high tensile strength, good ductility and impact resistance. These characteristics make them suitable for applications requiring reliable performance under heavy loads, dynamic stresses and harsh operating conditions.
Machinability: Hollow bars have good machinability and can be used for various machining operations such as turning, drilling, milling and threading. They can be easily cut, shaped and modified to meet specific design requirements. The consistent cross-sectional shape of hollow bars ensures dimensional accuracy and facilitates precision machining
Hollow rods are widely used in mechanical engineering applications where strength, durability and precision are critical
We produce in strict accordance with EN10294-1 standard specifications, and the hollow bars we produce undergo strict quality control measures to ensure that they meet the usage requirements.
