Product Description:
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
feature:
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.
