What materials can be formed using Pressure Sequence Hydroforming?
A- Pressure Sequence Hydroforming (PSH) is compatible with most metals, if it can be made into a tube PSH can form it. The process that normally establishes the required material elongation is the prebending operation. Vari-Form has formed HSLA materials in production for over 12 years and in 2008 will be entering production with DP 780. PSH has proven process compatibility with High Strength steel up to 960 Mpa UTS, Dual Phase, and TRIP steels. In addition to carbon steel the PSH process has been used to form both 5000 and 6000 series aluminum, and numerous grades of stainless steel.
