Mandrel Bars for seamless tube production
We are also one of the leading suppliers of Mandrel Bars to the Seamless Steel Pipe producers like ISMT, Jindal SAW, Maharashtra Seamless & BHEL.
Depending on the process, the tools, such as pilger mandrels, mandrel bars, rolls, etc., are exposed to a range of different stresses, which result from the varying periods of contact between the tools and the material at rolling temperature.
Steels must contain a balanced mix of alloys in order to achieve the longest possible service life and thus high tonnage per tool insert. Steels used for tube manufacturing must meet the following demands.
Good high-temperature strength, Low susceptibility to hot cracking, resistance to high-temperature wear and excellent high-temperature toughness.
SKI supplies mandrels either in fully machined chromium plated or scaled condition or in rough machined (tempered and peeled) condition. In addition to universally applicable standards steels, we offer specialty steels specifically tailored to different manufacturing processes and individual customer requirements
