Co. has introduced two new grades of alloy steel, 4130HW and
4140HW, that are designed for heavy-wall seamless mechanical
tubing applications needed by energy producers.
The grades meet
American Iron and Steel Institute 4130 and 4140 standards.
"We are seeing
applications where customers were asking for higher mechanical
properties, impact properties deep into the product. As we saw
these requirements coming in, (the grade development) was about
getting higher strength and toughness deeper into (the wall
thickness)," Shawn Seanor, vice president for Timken
Steels energy and distribution sectors, told
require small inner diameters with heavy walls, he said, such
as boring specialties with, for example, a 2-inch hole in a
applications where the 4130HW steel would be particularly well
suited include oil and gas drilling and completion equipment
such as packers, liner hanger components, drilling jars and
fishing tools. Customers also specify 4140HW steel for wellhead
components such as ball and gate valves, manifolds, crossover
flanges, adapter flanges, slips and blowout preventers.
Between 20 and 25
percent of Timkens bar and seamless tubing business ends
up in the oil and gas sector.
"Its a great
market in which to participate," Seanor said, as such customers
"value new grades of steel and their availability."
The two grades should
attract additional orders with existing energy customers as
well as new accounts, he said.
