Although hydroforming has gotten a lot of publicity in the last 20 years, a similar but lesser-known process, high-temperature metal gas forming, has been in use for more than 15 years. Because HTMGF works at elevated temperatures, it is useful for making complex shapes in titanium and aluminum, and it is making inroads into other industries as well.

As demands for higher tensile steel increase, width consistency and edge quality are increasingly important because high-strength material does not form like soft grades of steel. Using a precise system for evaluating coil dimensions and edge quality is more important now than ever before.

Superior Tube Co. Inc., Collegeville, Pa., a fabricator that draws tubing for small-diameter applications, recently set about to improve material flow through its plant. Realizing that moving 60- and 70-year-old draw benches likely would damage the motors and motor controllers, which were the original equipment, the company developed a plan to upgrade the hardware at the same time. The result is a quantum leap in motor efficiency and monitoring capability.

Applying a corrosion prevention product to steel isn’t enough. If the workpiece is contaminated with something as minor as fingerprints or steel fines, corrosion can get a foothold. Understanding the components that make up a corrosion cell, and how a corrosion cell works, is necessary in learning how to prevent corrosion from getting a start.
