Revolutionary steel treatment paves the way for radically lighter, stronger, cheaper cars

Back in 2011, we wrote about a fascinating new way to heat-treat regular, cheap steel to endow it with an almost miraculous blend of characteristics. Radically cheaper, quicker and less energy-intensive to produce, Flash Bainite is stronger than titanium by weight, and ductile enough to be pressed into shape while cold without thinning or cracking. It’s now being tested by three of the world’s five largest car manufacturers, who are finding they can produce thinner structural car components that are between 30-50 percent lighter and cheaper than the steel they’ve been using, while maintaining the same performance is crash tests. Those are revolutionary numbers in the auto space.

Darren Quick did a good job explaining exactly how Flash Bainite is produced in our original story, but in basic terms, you take regular, off-the-shelf AISI1020 carbon steel, and instead of heat treating it for 10 minutes like costly alloyed steel, you put it through a roller-driven system that induction-heats and liquid-cools the steel in a matter of 10 seconds or so.

Gears are a common component of modern machinery, found in gearheads, watches, motors, furnaces, and automation equipment. Due to the ease of manufacturing and the variety of alloys available, metal alloys are the most common material used for gears. However, alternatives are available: ceramic and metal injection molding offer higher strengths and other properties that make them desirable.

Read more about the advantages of various metal gears, ceramic gears, and the growing use of possible use of metallic glass as a future replacement material.
