It may also contain other elements such as chromium and nickel. Steel's properties, including its strength, durability, hardness, and ductility, are influenced by its carbon content and the addition of other alloying elements. It is heat-treated to improve strength and toughness and is known for its recyclability and resistance to corrosion and heat. Steel is widely used in construction, manufacturing, automotive, and infrastructure. 铁碳合金，是以铁和碳为组元的二元合金。铁基材料中应用最多的一类——碳钢和铸铁，就是一种工业铁碳合金材料。钢铁材料适用范围广阔的原因，首先在于可用的成分跨度大，从近于无碳的工业纯铁到含碳4%左右的铸铁，在此范围内合金的相结构和微观组织都发生很大的变化；另外，还在于可采用各种热加工工艺，尤其金属热处理技术，大幅度地改变某一成分合金的组织和性能。 Fe, C (plus other elements depending on the type of steel) 0 Product flow 2024-04-16T19:00:23.331753+08:00 ILCD format 00.01.05 Mass 1.0
