What are the knowledge points about stainless steel?
Stainless steel is a corrosion-resistant alloy steel, which has excellent rust prevention capabilities due to its chromium and nickel content. Here are some knowledge points about stainless steel:
Composition: The main elements of stainless steel are iron and carbon, but it also contains alloy elements such as chromium, nickel, and manganese. Chromium is the main element that gives stainless steel its corrosion resistance, and when the chromium content exceeds 12%, a difficult-to-dissolve oxide film forms on the surface, giving it excellent corrosion resistance.
Types: There are many different types of stainless steel, such as 201. 304. 316. etc. The main difference between them lies in the content and ratio of alloy elements. For example, 304 stainless steel contains higher amounts of chromium and nickel, while 316 stainless steel adds molybdenum, enhancing its corrosion resistance.
Processing: Stainless steel can be processed into various shapes and products, such as sheets, pipes, rods, wires, etc., as well as various kitchen equipment and industrial parts.
Surface treatment: Stainless steel can be enhanced in terms of aesthetics and corrosion resistance through surface treatments such as polishing, brushing, sandblasting, etc.
Identification: Stainless steel can be identified by its color and texture. Generally, high-quality stainless steel products have a smooth and shiny surface that is not easily rusted.
Maintenance: Although stainless steel has good corrosion resistance, it also requires proper maintenance and care. It should be cleaned promptly after use, avoid using bleach and strong acid or alkali cleaners, and regularly polished and oiled for upkeep.
