Increased hardness is easier to machine CANTON, Ohio, Oct. 31
/PRNewswire/ -- The Timken Company (NYSE:TKR) collaborated with one
of its major automotive customers to produce a steel that is easier
to machine. (Logo:

the Robert Bosch Corporation, Timken engineers developed a
hot-rolled temper process to produce steel that Bosch could more
readily machine for a diesel fuel injector on truck engines. "This
collaboration illustrates Timken's ability to custom-design
materials and offer value-added solutions that optimize the
performance of customers' applications," said Linn Osterman, vice
president of sales and marketing in Timken's Steel Group. "Timken
is committed to working closely with customers like Bosch to
translate our know-how into better performance." Bosch, a leading
manufacturer of automotive and industrial technology, previously
used a low-alloy steel that was hot-rolled annealed at its plant in
Charleston, S.C. This process produced steel with a high
surface-to-core hardness gradient that was difficult for Bosch to
machine. Excessive metal buildup on the tool edges ultimately led
to reduced drill and tool life. In 2005, Timken suggested a
hot-rolled temper process, which would produce steel that would
machine more efficiently and respond more effectively during
Bosch's heat-treatment process. This hot-rolled process would
produce tempered steel with a higher hardness and significantly
reduce the temperature required for heat treatment. After
conducting machining trials and component testing, Bosch confirmed
the improved machinability of the steel utilizing the Timken
process. "The high pressure pulsation fatigue life of the
hot-rolled tempered steel improved notably over that of the
hot-rolled annealed steel," said Wilt Staples, senior purchasing
engineer at the Bosch Charleston plant. Timken also provides
Timken(R) Generation III(TM) (Gen-III) integrated hub assemblies
for wheel-end applications in select North American vehicles. The
Timken integrated units are incorporated into Bosch wheel-end
assemblies for use in several General Motors trucks and vehicles,
including GMC 4x2 and 4x4 pickups, GMC 4x4 SUVs and the H3, the
latest addition to the Hummer line of on- and off-road vehicles.
