The secondary steel-making procedure involves refining and alloying the steel. It might both initialize with the usage of scrap steel or become a continuation of the principal process.

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。

Typically, incredibly hot rolled steel features a rougher, far more scaly end that might also consist of slight distortions and non-uniformities in form. The cooling method may end up in shrinkage and a little bit much less precise dimensional precision.
