Rolling

Bar Rolling Sevices

Overview ( brochure )

High Performance Alloys Inc. has added rod, hex, square, flats and strip production capabilities to our facility. We can now supply, custom rolled, small to medium quantities - all with short production lead times.

HPAlloys caters to special requirements including research projects to nuclear orders, and everything in between. No job is too small.

Capabilities

2-High rolling mill used for small round bar, square bar, rectangular and flats. We have also been rolling hex with this equipment. All work performed is cold, allowing a good finish on rolled materials.

Capabilities
Shape
Input Size
Output Size
Rod
3.5" maximum diameter
6" minimum length.
Most alloys will reduce to 3/16" diameter.
Many popular sizes are available.
Square
2" maximum square
6" minimum length.
1.75" through 0.562" square.
Many popular sizes are available.
Flat
5" maximum thickness, 3" wide
6" minimum length.
Most alloys will reduce to 0.020" thick.
Strip
0.25" thick & up to 10" wide
Re-coiling end product may be necessary.
Most alloys will reduce to 0.020"thick.
Minimum lengths can be overcome through fastening, or tacking a material to the piece to achive length.

We use approved processes to work the metal. Control of the materials overall heat loss is controlled using an optical pyrometer, and coatings if necessary.

Our 12 foot furnace is capable of 2300°F, and is routinely operating between 1500 and 2250°F. This furnace has computer controlled programming capabilities for  temperature control, and recording.

When hot working rods, and flats, the furnace is used to heat the metal to rolling temperature.

The gas furnace is typically operated neutral to slightly oxidizing. Temperature surveys are performed at least once per year.

Applications

HPA supplies materials to the aircraft, space, military, nuclear, electronics, marine, chemical, petro-chemical, and other high-tech industries.

There are a wide array of applications that can be summed up into one of the following categories: stronger parts, longer lasting, reduced cross sections (lighter), or material availability.

Hot & Cold Rolling


This United Engineering rolling mill can withstand 600 tons of force while rolling. Cold reductions as great as 70% have been performed on material 6 inches wide.

    Roll Diameter: 8"
    Roll Width: 12"

Tolerances on cold rolled rod material will be in the range of +/- 0.015" to +/- 0.005", depending on the diameter and condition of the material.

Tolerances on flat cold rolled material, including strip will be in the range of +/- 0.005" to +/- 0.001", depending on the thickness, width and condition of the material.

Tolerances on flat hot rolled material, including strip will be in the range of +/- 0.020" to +/- 0.010", depending on the thickness, width and condition of the material.

Benefits

Rolling allows for a wide array of mechanical properties in the annealed, and cold reduced state. Advantages include: changing customers material to a desired finished size without expensive turning or grinding of stock. We are capable of producing rod lengths over 36 feet, and also flat coils in the unannealed condition.

  • HPAlloy's rolling mill is used for quick turn around, and small quantities.
  • Produce a size, form or temper to your specifications.
  • Convert stock that is not moving into a useful size.
  • Improve mechanical strength properties.
  • Obtain finer grain structure and controlled grain growth.

Monel, Inconel, Incoloy are registered trade names of Special Metals
