Hydroforming DP 780 Steel Tubes
The advancement in high strength steel can be seen by the use of hydroforming DP 780 Steel tubes . It provides an innovative technology that can not only lower the cost of steel frame fabrication, but also optimize industrial use. When the DP 780 tubes are hydroformed, they provide a lighter but stronger steel frame.
Below are the results according to an article explaining the strength of internal pressure for the end feed (EF) of hydroformed DP 780 tubes.
- At zero EF the average pressure burst was 70 MPa or 10,075psi
- With an EF of 50%, the hydroformed DP 780 tubes could withstand an internal pressure of 151.7 MPa or 22,000psi
The dimensional capability of this steel will be the future in our automotive industry. The design flexibility along with the lower cost and increased strength using the hydroformed DP 780 tubing allows for improvement in crash-worthiness among motor vehicles.
In 2013 Ford introduced its new Ford Fusion vehicle featuring hydrofromed DP 780 tubes used for its B-pillar and A-pillar roof rails. Ford’s technical leader, Shawn Morgan quotes from an article found in SAE international,
“Using hydroforming instead of hot-stamped welded sheet to create the car’s roof-pillar structure reduced mass, saved cost, reduced the bill of material, and helped improve the new Fusion’s crash performance.”
Environmentalists will also approve of this new found technology. The use of dual phase steel provides not only a stronger and lighter means of transportation, but also decreases the amount of carbon dioxide emission given off by those vehicles. The use of hydroforming the stronger, more versatile DP 780 tubes does so without sacrificing the passengers safety if an accident were to occur.
