Scalpels and scalpel blades, sterile

Carbon steel, which the blades of our scalpels are made of, is an alloy of iron and carbon (and possibly other elements) containing a percentage of carbon not exceeding 2.1%. The carbon particles give the steel qualities of resistance, hardness and elasticity. The carbon particles interpose themselves in the microcrystalline structure of the iron, blocking the sliding and dislocations of the atomic planes.

Stainless steel or inox steel is characterized by greater resistance to oxidation and corrosion than carbon steel. This ability is mainly due to the presence of chromium, capable of passivating itself, i.e. covering itself with a thin and adherent layer of oxides which superficially protects the underlying metal or alloy from the action of oxygen and external chemical agents.
