PIERCING (ROTARY FORGING)
Piercing a seamless steel tube is a forging operation in which the metal is worked from the inside as well as the outside. We convert a solid bar into a hollow shell by displacing material over a mandrel during rotary rolling. This process results in a refined grain structure and uniform grain flow. Subsequent seamless tube processes include elongating to reach the desired wall thickness, rolling to achieve the outside diameter, and rotary sizing to round the tube diameter to your final required dimensions. We monitor these operations to produce a tube with uniform properties from the surface through wall and from one end to the other.
THERMAL TREATMENT
We house multiple thermal treatment facilities that tailor solutions to meet a wide range of customer needs. We also operate two Induction Thermal Treatment Facilities (ITTF), a Continuous Thermal Treatment Facility (CTTF), a Quench Temper Facility (QTF), a Gambrinus Thermal Treat Facility (GTTF) and our newest Advanced-Quench-and-Temper Facility (AQTF) in Canton, Ohio. At these facilities, we provide a diverse range of processing options to meet demanding strength and hardness requirements – regardless of the order size. We continue to develop these facilities, advance our capabilities and broaden our sophistication in thermal treatment offerings so you can rely on TimkenSteel for innovative product designs and proven quality.
TESTING AND FINISHING
Our $50 million intermediate finishing line (IFL) in Canton incorporates the latest technologies and employs lean processes. This significantly eliminates product touches and material movements, helping improve your lead times. Our state-of-the-art finishing processes through the IFL include straightening, water blast scale removal, cutting, ultrasonic testing, eddy current testing, and dimensional gauging. IFL testing capabilities include hardness, strength, and toughness and cleanness testing in order to meet your specifications.
