While there is a lot of discussion of alternative materials for vehicle manufacture nowadays, one of those alternatives just
may be something that’s in the 3GAHSS category—that’s as in “third-generation advanced high-strength steel.” Of course, “3GAHSS” just sounds more up-to-date than steel, doesn’t it?
There's plenty of buzz about materials other than steel because steel has been used for body applications for so long. But the steel industry is working so that its products will be anything but antique.
Perhaps because steel has long been used in the auto industry, some engineers think that the material is old-hat, that different materials have to be used in order to develop vehicles that are lighter and so more fuel efficient. But 35 steel companies from 18 different countries are proving that steel is as high tech and as capable as anything available, and they're building a car to prove it. And, oh, by the way—steel is a whole lot more economical than the competition, too.
Here's a look at a study that was conducted by a committee of the American Iron and Steel Institute to determine whether steel could be used to create big, safe and light-weight sport utility vehicles and light trucks.
