Thekey difference between stainless steel and sterling silver那是不锈钢比纯银不那么明亮,光泽,它的外观非常闪亮。
An alloy is a mixture of two or more metals with some other chemical elements. Stainless steel and sterling silver are two important alloys with various important applications. These two alloys have different appearances, so it’s not difficult to distinguish between these two alloys.

What is Stainless Steel?
不锈钢是一种合金钢consisting of 10-30% of铬。它的碳含量低,其铬倾向于给予显着的抵抗力corrosionand heat. Other chemical elements such as nickel, molybdenum, titanium, aluminum, niobium, copper, nitrogen, etc., can also be added to it. These additions increase the corrosion resistance to specific environments, enhance oxidation resistance, and impart special characteristics.
There are about 100 different grades of stainless steel. We can classify the majority into five major groups known as austenitic, ferritic, martensitic, duplex, and precipitation-hardening.
通常,不锈钢在美学上具有吸引力,极其卫生,易于维护,高度耐用,并提供了各种各样的方面。因此,我们可以在日常物品中找到不锈钢,在这些物体中,它在能源,运输,建筑,研究,医学等一系列行业中起着重要作用。
奥氏体不锈钢has about 21% chromium and about 0.10% carbon, along with some other chemical elements. The applications of this material include boiler market, electronic components, railway equipment, tubes, chemical tanks, etc.
The other most common form of stainless steel is ferritic stainless steel. It has about 30% chromium and 0.06% carbon. It is important in applications such as car exhaust systems, cooking utensils, boilers, domestic appliances, etc.
What is Sterling Silver?
Sterling silver is a type of alloy of silver consisting of about 92% of its weight in silver and the rest in other metals. Typically, fine silver has about 99% purity. Fine silver is relatively soft, so it is usually alloyed with other metals such as copper to increase its hardness and strength. Moreover, this alloy is prone to tarnishing, and we can use metals other than copper to reduce this tarnishing effect. In addition, we can add other chemical elements to cast porosity and firescale. The chemical elements that we can use in this context include germanium, zinc, platinum, silicon, and boron.
There are many different uses of sterling silver, including the manufacture of forks like dinner forks, salad forks, pastry forks, spoons like teaspoons, coffee spoons, iced tea spoons, and knives like dinner knives, butter spreaders, cheese knives, etc.
In chemical terms, silver is not a much reactive metal. This means it does not react with oxygen or water at ordinary temperatures; therefore, it does not form silver oxide easily. However, the common components in atmospheric pollution can attack this metal easily. For example, upon exposure to airborne sulfur compounds, silver forms silver sulfide, which appears as a black tarnish. Therefore, the decrease in the purity of silver can cause a higher rate of corrosion or tarnishing. Besides, other metals in the alloy like copper can react with oxygen in the air.
What is the Difference Between Stainless Steel and Sterling Silver?
不锈钢和纯银之间的关键区别在于,不锈钢较不亮和有光泽,而纯银的外观非常闪亮。此外,不锈钢的重量高于纯银。
摘要 - 不锈钢与纯银
不锈钢是一种合金钢consisting of 10-30% of chromium, while sterling silver is a type of alloy of silver consisting of about 92% of its weight with silver and the rest with other metals. The key difference between stainless steel and sterling silver is that stainless steel is less bright and lustrous than sterling silver, which has a very shiny appearance.
