Iron vs Steel: What's the Difference? - Monroe ...
Steel, for example, is both harder and stronger than pure iron. And unlike iron, steel isn't an essential mineral. You don't need to consume steel as part of your diet. The primary difference between iron and steel is that the former is a metal, whereas the latter is an alloy. Iron is simply a metal element that occurs naturally on Earth.

Ball Milling | Material Milling, Jet Milling | AVEKA
Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion, the particles in between the media and chamber walls are reduced in size by ...

Stainless Steel - K&J Magnetics
Some steels are only weakly magnetic, and some are not magnetic at all. Austenitic stainless steels like 304 or 316 stainless are good examples of this. A ferritic stainless like 430 stainless steel, on the other hand, is ferromagnetic. Magnets stick to it. You might see magnetic forces that are 5-20% weaker compared to low carbon steel.
