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。

Steel is surely an amazingly multipurpose metal and has lots of varieties and grades. Outlined underneath are a few of its apps:

ASTM A106: This quality of steel pipe is employed get more info for top-temperature applications, including in boilers and heat exchangers. It has a minimum generate energy of 245 MPa plus a most discover this produce strength of 415 MPa.

Sure, steel can rust. Rust happens if the iron in you can look here steel reacts with oxygen from the air (inside the presence of water) to sort iron oxide. Stainless steels, however, have alloying components including chromium and nickel that reduce or seriously inhibit iron oxide development.

This Device is water quenched for the duration of use and is easily the most very affordable tooling sort. Extensively used to make common tools.

A Bessemer converter in Sheffield, England Since the seventeenth century, the initial step in European steel production has the original source been the smelting of iron ore into pig iron inside of a blast furnace.

It involves a discount course of action, which happens to be utilized to lessen the iron oxide present. A lowering agent referred to as oxygen carbon is accustomed to independent the iron atoms.

Standard specification for cold-shaped welded and seamless carbon steel structural tubing in rounds and shapes

Standard specification for steel sheet, metallic coated and polymer precoated for corrugated steel pipe

Steel is Just about the most practical materials on this planet. official website In the simplest context, steel is made up of iron and carbon, but in truth, steel isn’t so very simple.
