不锈钢是一种合金钢,所谓合金钢就是在钢中加入一定量的合金元素,而形成的钢种。合金钢中最常用的合金元素有锰、硅、矾、钨、钛、铬、镍、铝、铜、磷等。这些合金元素的加入,可以改善钢的机械性能,比如提高钢的强度,并仍保持原来的塑性和韧性;或者获得耐腐蚀,耐热和低温等特殊性能。因此,随着现代化学工业,炼油工业、航空、动力、喷气和火箭技术、原子能工业等高速度的发展,合金钢的应用范围日益广泛。
Stainless steel is an alloy steel, the so-called alloy steel is added in the steel a certain amount of alloying elements, and the formation of steel. Alloy steel is the most commonly used alloying elements manganese, silicon, alum, tungsten, titanium, chromium, nickel, aluminum, copper, phosphorus and so on. The addition of these alloying elements can improve the mechanical properties of the steel, such as increasing the strength of the steel, while still maintaining its original ductility and toughness, or achieving special properties such as corrosion resistance, heat resistance and low temperature. Therefore, with the rapid development of modern chemical industry, oil refining industry, aviation, power, jet and rocket technology, atomic energy industry, the application of alloy steel is becoming more and more widespread.
