Stainless steel (8)

 　　Carbon C: can increase hardness and strength, but excessive content will reduce its ductility and corrosion resistance

　　Chromium Cr: can increase corrosion resistance, oxidation resistance, refine product particles, increase strength, hardness, and wear resistance

　　Ni: It can increase high temperature strength and corrosion resistance, and reduce the rate of cold working and hardening

　　Molybdenum Mo: increases strength and has excellent corrosion resistance to nutrients and seawater

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.

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...

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...
