It is the principle strengthening element in carbon steels and low-alloy steels. Atomic number 6, atomic weight 12.01115. Manganese (Mn): Manganese is a brittle, metallic element that exists in ...

Even steel — a hard alloy of iron with traces of carbon — easily rusts, which means oxidation damages the steel in buildings, cars and appliances. But, as its name suggests, stainless steel ...

The diagrams show the effect of changing the carbon content on the mechanical properties of low carbon steels that have been annealed. It is seen (a) that the ultimate tensile strength of these alloys ...

The alloy is harder and stronger than the pure metal. Steel contains atoms of other elements as well as iron. These atoms have different sizes to iron atoms, so they distort the layers of atoms in ...
