钢铁一般依照它的提炼方法可分为柏塞麦转炉钢，碱性转炉钢，平炉钢，电炉钢等。依所含成份则可分为碳钢，低合金钢，高合金钢等。依其产品形状则分为形钢，棒钢，钢板。为了特殊目的，而加入各种合金元素可得特殊合金钢。
In accordance with the general steel refining method it can be divided into the Bessemer converter basic converter steel, steel, steel, electric steel etc.. According to the contents can be divided into carbon steel, low alloy steel, high alloy steel etc.. According to the shape of the product, it can be divided into shape steel, bar steel and steel plate. Special alloy steels can be obtained by adding various alloying elements for special purposes.
高温钢用于制造锅炉在500℃到600℃的温度下连续使用，仍能保持其机械特性。铜是高温钢的主要合金元素。耐热钢在钢中加入铬、镍和硅能使钢耐1300℃之高温。此种钢通常用于制造工业用炉及电阻丝等。在钢中加入少量铜可延缓钢在空气中的腐蚀率。若在钢中加12％以上之铬则可避免钢之腐蚀。目前食品工业及化学工业正广泛地使用不锈钢。厨房用具，餐具和外科用具也用不锈钢制造。

High temperature steel can be used continuously for 500 hours to 600 degrees, and its mechanical properties can still be maintained. Copper is the main alloying element of high temperature steel. The addition of chromium, nickel and silicon into the steel can make the steel resistant to 1300 degrees of high temperature. This kind of steel is usually used to make industrial furnaces and resistance wires. Adding a small amount of copper into steel can retard the corrosion rate of steel in air. If more than 12% chromium is added in the steel, the corrosion of steel can be avoided. Stainless steel is widely used in the food and chemical industries. Kitchenware, tableware and surgical instruments are also made of stainless steel.
工具钢的含碳量高于结构用钢，通常用于制锯条，钻头等。特殊钢则加入铬、钨、钴、钼、钒等合金元素，并经适当的热处理。由以上可知钢铁的种类非常多，而各种钢铁成品各有其特殊的用途
The carbon content of tool steel is higher than that of structural steel, which is usually used for making saw blades, drills and so on. Alloying elements such as chromium, tungsten, cobalt, molybdenum and vanadium are added to the special steel and treated by proper heat treatment. From the above we can see that there are many kinds of iron and steel, and all kinds of steel products have their own special uses
