Other materials in many cases are extra to the iron/carbon combination to generate steel with the specified Homes. Nickel and manganese in steel incorporate to its tensile power and make the austenite type of the iron-carbon Resolution additional steady, chromium boosts hardness and melting temperature, and vanadium also boosts hardness when making it fewer prone to metal exhaustion.[7]
儘管在文藝復興之前很久，人們已經懂得使用各種低效的方法來生產鋼，但是鋼的普及化要等到十七世紀，也就是有了更高效的生產方法之後。自從在十九世紀發明了貝塞麥煉鋼法之後，鋼就成了一種可大量生產的廉價材料。後來煉鋼法經過更多的改進，例如鹼性氧氣煉鋼法，使得鋼的生產價格更低，但同時品質更好。時至今日，鋼已經成為世界上普遍的材質，年生產量達十三億噸。在各種建築、基礎設施、工具、船隻、汽車、機械、電器及武器中，鋼都是一種主要的成份。現代鋼鐵一般用各種標準化團體所制定的不同品質標準來區分。
In pure iron, the crystal structure has relatively small resistance towards the iron atoms slipping past one another, and so pure iron is fairly ductile, or tender and easily formed. In steel, compact quantities of carbon, other components, and inclusions within the iron work as hardening brokers that avert the movement of dislocations.

Following the forming course of action, warm rolled steel items will scale when in connection with oxygen and h2o vapor. Guard incredibly hot rolled steel products and solutions from corrosion with pickled and oiled and pickled dry floor treatments, which defend in opposition to inorganic contaminants, rust, and scale.
