合金钢是以铁为主体,混熔有铬、钨、锰、钼等金属。它具有硬度大、难磨损的优良性能,因而广泛应用在制造各种模具上。 从理论上说,铁遇到强酸溶液会被氧化溶 解并放出氢气,但合金钢因混熔了其它金属,改变了铁的结构,降低了铁的活性,在合金钢中分别滴加硫酸、盐酸或硝酸都未见到被腐蚀的痕迹。因而在合金钢模中刻上字样或图案,现在
Alloy steel is iron-based, mixed with chromium, tungsten, manganese, molybdenum and other metals. It has excellent properties of hardness, hard to wear, and is widely used in the manufacture of various molds. Theoretically speaking, iron encountered strong acid solution will be dissolved and dissolved and release hydrogen, but the alloy steel due to the melting of other metals, changes the structure of iron, reducing the activity of iron, in the alloy steel, respectively, sulfuric acid, hydrochloric acid No trace of corrosion was found in either nitric acid or nitric acid. Therefore, the words or patterns are engraved in the alloy steel molds. Now
