The areas of commercial use are as broad as our world itself, and beyond.
The most obvious use of Bainitic High Strength Steel (BHSS) is in sheet form in the transportation industry. The increased ductility of a bainitic microstructure will allow stamping of part configurations never possible with existing martensitic Advanced High Strength Steels (AHSS). A significant number of complex stamped components will soon be manufactured in much thinner gages of steel due to the excellent formability of BHSS. Imagine an automobile whose stiffness has been increased yet weighs hundreds of pounds less.
Another area of increased use will be in the field of civil engineering. Steel building components can be manufactured to rely on much higher tensile strengths than previously thought possible. Wall studs, bar stock, angle iron, and I-beams are just some of the shapes that can be converted to bainite using this process. Significantly lighter roof trusses could be completely constructed from thinner gauge bainitic members that rely on greater tensile strengths. Tensioning components such as wire and re-bar may positively impact the bridge and highway building industries. Just imagine how much less steel could be used in a suspension bridge if architects could rely on much higher tensile strength cables.
Other areas as diverse as household appliances to stronger armor plating to space craft will be able to take advantage of Bainitic High Strength Steel.
