CHICAGO Timken 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 AMM.
Many applications require small inner diameters with heavy walls, he said, such as boring specialties with, for example, a 2-inch hole in a 13-inch-diameter bar.
High-yield-strength 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.
