Medium carbon steel has approximately 0.30–0.59% carbon content (e.g. AISI 1040 steel). It balances ductility and strength and has possess ecellent wear resistance. It is used for large parts, forging and automotive components.We are recognised as the leading dealer and distributor medium carbon steel in the steel industry.
Carbon steel, also refered as plain carbon steel, is a metal alloy, a combination of two elements, iron and carbon, where other elements are present in quantities too small to affect the properties. The only other alloying elements allowed in plain-carbon steel are manganese (1.65% max), silicon (0.60% max), and copper (0.60% max). Steel with a low carbon content has the same properties as iron, soft but easily formed.
Carbon content influences the yield strength of steel as it fits into the interstitial crystal lattice sites of the body-centered cubic arrangement of the iron molecules. The interstitial carbon reduces the mobility of dislocations, which in turn has a hardening effect on the iron. To get dislocations to move, a high enough stress level must be applied in order for the dislocations to "break away". This is because the interstitial carbon atoms cause some of the iron BCC lattice cells to distort.
