Stainless steel magnetic standard

图片
 　　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...

Differences between 304 and 316 stainless steel

图片
 　　Austenitic stainless steel is usually used when selecting stainless steel that must withstand corrosive environments. Austenitic stainless steel contains a large amount of nickel and chromium, which has excellent mechanical properties and corrosion resistance. In addition, many austenitic stainless steels are weldable and formable. The two more commonly used austenitic stainless steel grades are 304 and 316. To help you determine which brand is suitable for your project, this blog will study the differences between 304 and 316 stainless steel 　　304 stainless steel 　　Grade 304 stainless steel is usually considered the most common austenitic stainless steel. It contains high nickel content, usually between 8% and 10.5% by weight, while chromium content is high, about 18% to 20% by weight. Other major alloying elements include manganese, silicon, and carbon. The rest of the chemical composition is mainly iron. 　　The large amount of chromium and nickel gives 304 stain...
