EN10305 WT12 E235 Round Precision Steel Tube , Cold Drawn Hollow Seamless Tube For Mechanical

EN10305 Round Precision Steel Tube , Cold Drawn Hollow Seamless Tube For Mechanical

Description:

Round precision steel tubes and cold drawn hollow seamless tubes are crucial for mechanical applications, offering high strength and durability. These tubes are manufactured through cold drawing, enhancing their dimensional accuracy and surface finish. Their seamless construction eliminates weak points, making them ideal for high-pressure environments. Commonly used in automotive, aerospace, and machinery sectors, these tubes ensure reliable performance and longevity. With exceptional mechanical properties and uniformity, they support efficient designs and contribute to the overall integrity of various engineering projects.

Mechanical properties at room temperature:

Delivery Condition:

1. NBK(+N)
after cold forming, eventually above phase transition point, in a protective atmosphere of annealing oxidation medium
2. GBK(+A)
after cold forming, annealing in non oxidizing medium protective gas
3. BK(+C)
the final heat treatment after cold forming, threfore small steel pipe plasticly, the plasticly degree does not guarantee
