Features of 420 Stainless Steel Strips
The higher hardness of 420 stainless steel strips is due to its chemical composition and heat treatment method. 420 stainless steel strips are mainly composed of chromium and carbon, where the chromium content is about 12-14% and the carbon content is between 0.12-0.25%. This composition allows 420 stainless steel strips to have high hardness, strength and wear resistance.
In addition, 420 stainless steel strips need to be properly heat treated to achieve their optimum properties. During the quenching process, the strips are heated to high temperatures and cooled rapidly, which helps to increase their hardness and strength. If the strip requires higher hardness, it needs to be tempered to make it more ductile and machinable.
420 stainless steel strips are less resistant to corrosion compared to other stainless steel types due to its high carbon content and lower chromium content. However, with proper heat treatment, it can achieve high hardness and good resistance to wear and tear. In addition, if used and maintained correctly, 420 stainless steel strips can also exhibit good corrosion resistance. Therefore, in practical applications, it is important to choose the right stainless steel material according to the specific situation and adopt the correct usage and maintenance methods to ensure its performance. As a professional stainless steel strip supplier, Huaxiao Stainless Steel offers high quality 420 stainless steel strips to meet the needs of a variety of different applications.
420 stainless steel strips are martensitic stainless steels and therefore have a certain degree of magnetism. During processing, if subjected to overheating, ferrite may occur, resulting in increased magnetism. However, even under normal conditions of use, 420 stainless steel strips have higher magnetic properties than many other stainless steel strips. This also gives 420 stainless steel strips an advantage in some applications where magnetic materials are required, such as in the manufacture of watches and timepieces. At the same time, it is important to note that the magnetic properties of 420 stainless steel strips may affect some applications, such as the use of 420 stainless steel strips in certain special cases where non-magnetic materials are required, and caution is required.
420 stainless steel strips have good machinability and can be processed and deformed in many ways. It can be processed into parts and components of different shapes and sizes by cutting, stamping, bending, welding, deep punching, etc., which are widely used in different fields. In addition, 420 stainless steel strips can be precision machined by drilling, milling, turning, etc. to meet a variety of specific engineering requirements. The benefit of this machinability is that it can greatly increase productivity and reduce production costs, as the process can be more efficient and economical. In many industries, 420 stainless steel strips have become one of the materials of choice because they can be machinable while maintaining strength and corrosion resistance for a variety of applications.
The high surface finish of 420 stainless steel strips is due to its precision processing and polishing treatment during the production process. During the production process, 420 stainless steel strips are processed through multiple processes such as cold rolling or hot rolling, annealing, pickling and polishing to finally obtain a smooth and bright surface.
Due to the high surface finish of 420 stainless steel strips, they are widely used in some application areas with high requirements for appearance, such as manufacturing high-precision instruments, ornamental items, jewelry, etc. In some fields that require precision processing, such as electronics, optics, precision machinery, etc., 420 stainless steel strips can also be widely used.
