主要区别——铬与不锈钢
铬和不锈钢是金属器具或固定装置生产中使用最广泛的两种金属材料。虽然这两种材料看起来非常相似,性能相似,但它们却大不相同。由于这两种材料的成分差别很大,所以它们在性能和应用方面存在差异。不锈钢是一种主要含有铁、碳和铬的合金,而铬是镀铬材料,不能被视为合金。这就是铬和不锈钢之间的关键区别。
什么是铬(chrome)?
铬是铬的简称,通常指镀铬。镀铬是通过电镀在塑料或金属物体表面镀上一层铬层。这种技术用于装饰和工业用途。在装饰应用中,它除了增强审美特性外,还加强了物体。最常见的例子之一就是在摩托车侧面镀铬。活塞杆是镀铬工业应用的一个例子。铬以其光泽和耐腐蚀性而闻名。
什么是不锈钢(stainless steel)?
Stainless steel is an alloy made of steel and chromium; the minimum quantity of chromium is about 10.5% by mass. Stainless steel has some essential and versatile properties such as relatively low cost, high strength, higher resistant to staining, corrosion and rusting as well as its flashier luster. There are three types of industrial grade stainless steel varieties based on their composition; austenitic, martensitic and ferritic. Austenitic is a chromium-nickel-iron alloy (Cr-16% -26% , Ni -6%-22 and a low carbon content), Martensitic is a chromium-iron alloy (Cr-10.5% -17% with some carbon content) and Ferritic is a chromium-iron alloy (Cr- 17%-27% and a low carbon content). Many cooking utensils are made from ferritic type of stainless steel.
铬(chrome)和不锈钢(stainless steel)的区别
成分:
铬:铬只含有铬,它不是合金。
不锈钢:不锈钢是一种合金,除了铁和碳外,还含有至少10.5%的铬。它可能含有镍,也可能不含镍。由于镍是最昂贵的合金元素之一,其使用非常有限。
属性:
铬:铬的高光泽使它更加美观。然而,铬材料更容易受到污垢和污垢的影响。它比不锈钢便宜,但耐用性低。
不锈钢:不锈钢是一种合金,其耐用性相对高于铬。此外,它的耐腐蚀性和划痕性很低,因此,它不会失去光泽,而且很容易保持清洁。然而,它是非常昂贵的,与铬相比不那么闪亮。
使用:
Chrome:Solid Chrome(Chrome是唯一的元素)不用于构造对象。相反,它是作为一个薄薄的一层应用于由钢制成的物体,有时铝,黄铜,铜,塑料或不锈钢。
