Sept. 29, 2015
Ray Fryan
Vice President – Technology & Quality

2. Agenda Introduction – Steel as an engineering material
Tubing – Flexible steel product form
Process applicability
Welded and seamless
TimkenSteel process technology, process flow
TimkenSteel product applications
Wish list: Ideas to think about for the seamless tubing industry

3. Advancing the technical development, production, processing and application of iron and steel
Serving as a global leader in networking, education and sustainability programs

4. Steel: A flexible engineering material
…its great strength, uniformity, light weight, ease of use, and many other desirable properties make it (steel) the material of choice…” - University of Maryland civil engineering lecture notes, 2002
…”factors affect the ultimate performance of a component… include raw material, design, processing/product, and application variables…” - CV Darragh, The Timken Company, Gear Technology, 2002
…”the car of the future will be a multi-material construction in which composites and advanced metals will be combined to achieve the best performance/cost balance…” - Ross Kozarsky, Lux Research Advanced Materials, 2012
Steel – Competing for MOST engineering applications
… highest value option for MANY 4

5. Steel tubing space Function, cost (material attributes)
Tubing’s broad range of applications
Static / structural loading
Convey fluid / pressure
Transmit torque
Rolling
Fatigue loading
Welded, drawn over mandrel
Seamless pipe
Welded, drawn over mandrel: 12 to 1 larger than seamless mechanical
Seamless mechanical:
TimkenSteel
Seamless pipe:
5 to 1 larger than seamless mechanical
Seamless mechanical:
TimkenSteel 5

6. Tubing: Flexible ‘parts-making’ material
Annular parts – Obvious tubing space
Long parts (line pipe, drilling tools, hydraulic cylinders)
Short parts (gears, cages, liners)
Tubing enables efficient parts 6

7. Tubing  Welded and seamless
Welded – thinner wall, high dimensional precision
As-processed or drawn over mandrel (DOM)
Structural applications, fluid conveyance, fluid power
Seamless – thicker wall, weld zone not acceptable
As-processed or cold drawn/cold pilgered
“Where welded doesn’t work,” mechanical, metallurgical
Pipe – longer lengths, standard sizes
Mechanical – custom sizes
Torque transmission, rolling/sliding contact
Tubing – optimized for function and value 7

8. TimkenSteel process technology8

9. TimkenSteel tube-making process flow9

10. TimkenSteel tubing applications
Automotive
Transmission gears, hollow transmission shafts, axles, constant velocity joint cages, clutch races
General industrial
Defense, bearing
Oil and gas
Riser systems, packers, couplings, production liners
Seamless mechanical tubing – Flexible, small lot sizes, high yield, low operating costs … leveraging high-performance steel 10

14. Wish list: Ideas to think about for the tubing industry
Better (in-process) detection of tooling condition
Better thermo-mechanical recipe for superior properties
Strength/toughness, process ability (machining, heat treatment)
Better real-time process control
Dimensional precision, thermo-mechanical process
Better leverage of steel properties in- application 14
