Complete the text with the proper words:Steel is an alloymalleableductileresistantcarbon of iron (Fe) and alloymalleableductileresistantcarbon (C). The carbon content must not be more than 1-7%. Steel is very strong and alloymalleableductileresistantcarbon . When the carbon content is high, the steel is stronger and harder than when it is low, but steel with high carbon content is less ductile and less alloymalleableductileresistantcarbon to shock.
