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。

Having said that, this doesn't mechanically mean cold is healthier just because It can be more powerful and dearer.

Scorching-rolled steel is also equipped to take care of some give or strain, so it works properly for things like bridges, which can be supporting huge quantities of body weight. Very hot-rolled steel provides an affordable, sturdy selection for industrialized programs.

Cold-rolled steels are best utilised any time a very difficult design need to be constructed because it cools more uniformly than scorching-rolled steel. It works great for items which include automotive factors or home appliances.
