Describe the properties of stainless steel
Many people ask me why I choose stainless steel jewelry as my main business. I didn't think about it, so I told them, because stainless steel has the advantages of no corrosion, strong acid resistance, alkali resistance, no discoloration, no fading, no allergies, no deformation, hard and bright, no side effects, and harmless to human body.Here I want to talk about the material itself, stainless steel. Stainless steel is a kind of steel that is resistant to weak corrosive media such as air, steam, and water, and chemically corrosive media such as acid, alkali, and salt. Also known as stainless acid-resistant steel. In practical applications, the steel that is resistant to weak corrosive media is often called stainless steel, and the steel that is resistant to chemical media corrosion is called acid-resistant steel. Due to the difference in chemical composition between the two, the former is not necessarily resistant to chemical media corrosion, while the latter is generally stainless. The corrosion resistance of stainless steel depends on the alloying element chromium contained in the steel. Chromium is the basic element for stainless steel to obtain corrosion resistance. When the chromium content in the steel reaches about 1.2%, the effect of chromium and the oxygen in the corrosive medium is A very thin oxide film (self-passivation film) is formed on the steel surface, which can prevent further corrosion of the steel matrix. In addition to chromium, the commonly used alloying elements are nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the requirements of various uses for the structure and properties of stainless steel. Stainless steel models are: 200 series, 300 series, 400 series, 500 series, 600 series. We generally use 300 series for jewelry, but some manufacturers may use 200 series in order to pursue the lowest price. Basically, 200 series can not be regarded as stainless steel, but can only be called stainless steel. The most commonly used accessories are 304 and 316. Generally, European and American countries have relatively high requirements on materials, and 316L is used. 316 is the second most widely used steel after 304. It is mainly used in the food industry and surgical equipment. . After 316 polishing, the brightness and texture are super first-class.
