The difference between stainless steel and galvanized steel

图片
 　　Without protection, ordinary carbon steel is still prone to rusting in most environments. Therefore, there are many ways to modify steel to prevent corrosion. Two popular solutions are to use stainless steel or galvanized steel. Although both types of steel can resist rust and corrosion, there are important differences between them that should be understood. 　　What is stainless steel? 　　Stainless steel can resist corrosion because its chemical composition contains additional alloying elements. Although ordinary carbon steel is mainly composed of iron and carbon, stainless steel adds a large amount of chromium to help it resist corrosion. Chromium, sometimes with other alloying elements, is added to stainless steel during the initial melting process and then forms any specific shape. 　　What is galvanized steel? 　　Galvanized steel is a type of steel coated with a layer of zinc, which helps prevent rusting of the underlying steel. This layer is usually very thin, us...

Stainless steel magnetic standard

 　　The stainless steel grade plays a role in influencing factors, but generally speaking, stainless steel alloys have magnetism, and they must meet the following requirements: 　　The alloy must contain iron (Fe). 　　The crystal structure of stainless steel alloy must be arranged in martensite or ferrite structure. 　　Firstly, as stainless steel is a type of steel, its chemical composition must contain iron. This makes stainless steel magnetic. 　　The second requirement is that the crystal structure of stainless steel must be arranged into ferrite or martensite structure. If stainless steel is mainly composed of austenitic structure, it will not have magnetism. 　　As we have already mentioned, corrosion resistance is not related to magnetism. In stainless steel, corrosion resistance depends on the concentration of chromium (sometimes molybdenum). The more each, the better the corrosion resistance.

Tempering name for aluminum

图片
 　　 Aluminum is known for its versatility; Although its excellent corrosion resistance and thermal conductivity are very useful in many applications, the flexibility and adaptability of aluminum's mechanical properties make it a widely used metal. The mechanical properties of aluminum can be changed in many ways (such as adding alloy elements or work hardening), but one of the most popular ways to change the mechanical properties of some grades of aluminum is through tempering. Due to the significant impact of tempering on aluminum alloys, it is important to understand the names and meanings of aluminum tempering, so that misunderstandings do not lead to cracking and failure. 　　What is the name for aluminum tempering? 　　The aluminum tempering name is a series of letters and numbers used to indicate the type of tempering treatment that aluminum alloys have undergone. The tempering name is preceded by a dash and placed after the aluminum alloy name (such as 6061-T6). Un...
