6UDPlus Steel Cord Wire Drawing Grade

6UDPlus steel cord is a high-performance cemented carbide nib blank grade that maximizes wire die longevity and performance when drawing steel cord fine and ultrafine wires because of its corrosion-resistant and wear-resistant capabilities.

Die blanks of grade 6UDPlus steel cord are available in various standard geometries, including ISO, JIS, DIN, R-Series, and EDM. They can also be tailor-made to fit your wire die design.

There are no size limitations when using die geometries in grade 6UDPlus. However, Hyperion recommends only using grade 6UDPlus in die blanks with bore sizes below 3 millimeters for the wet drawing process.

6UDPlus steel cord is best utilized for wet drawing steel cord fine and ultrafine wires. The cemented carbide grade is proven to provide exceptional performances with wire drawing applications such as saw wire, tire cords, welding wire, magnet wire, and ultra-tensile wires.

There are minimal changes to the die-finishing process when using grade 6UDPlus compared to conventional carbide grades. As a cemented carbide grade, 6UDPlus steel cord grade allows wire drawing blanks and dies to be finished with the same process parameters as conventional carbides. Toolmakers can use the same diamond compounds and machinery for conventional carbide grades.

When wet wire drawing, it is not recommended to mix dies made of grade 6UDPlus with other conventional carbide or softer materials. 6UDPlus steel cord has a superior hardness compared to any conventional 6% cobalt ultrafine grade or 3% cobalt extra fine grade. Dies of softer carbide grades will oversize faster than 6UDPlus dies, leading to an unstable drawing process. All drawing dies should have the same carbide grade for consistent and superior drawing stability.
