The history of steel begins Together with the history of iron. Iron’s discovery and rise to prominence in what we now simply call the Iron Age commenced in regarding the twelfth century BCE (however it varies depending on geographical locale). It is only thought of to own began in Europe around the fifth century BCE.
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。
Stainless steels are utilized extensively in medical equipment since they resist corrosion. They don’t naturally market microbial advancement and can certainly be cleaned and in some cases heat-sterilized. Surgical tools and medical devices are commonly made from stainless steel.
