Carbon steel
Description
Steel is an alloy of iron with a small percentage of carbon. The amount of carbon present changes the iron from a soft easily worked metal into an extremely hard brittle metal.
--carbon steel Low carbon (mild, soft) steel contains less than 0.3% carbon. It works well when heated to redness and is easily cast. Soft steel is used in construction and as a substitute for iron wrought iron.
--carbon steel Medium carbon (normal) steel contains between 0.3-0.7% carbon. It is easily cast and forged into many shapes. Normal steel is also used for construction.
--carbon steel High carbon (hard) steel contains between 0.7-1.5% carbon. It is very hard and brittle and is used to fortify warships.
--iron Cast iron also contains carbon in concentrations up to 5%.
