Product Description

Precision Mild Steel Seamless Pipe EN10305-1 Cold Rolled Steel Tubes E355 BK

The advantage of steel tubes designed for precision applications is the high precision with which they are manufactured, the good quality of their surface, a wide selection of dimensions and guaranteed mechanical and technological properties. It is for those reasons that the pipes are widely used in the mechanical engineering industry and the automotive industry. Pipes for precision applications are manufactured as cold-drawn pipes.

The pipes are manufactured with diameters between 4 – 120 mm and with a wall thickness of up to 12,5 mm.
The pipes are manufactured without thermal processing or with thermal processing: normalization or annealing.
