What are the raw materials for making metal stamping?

With the development of science and technology and the changes of the times, the metal stamping industry has slowly penetrated into people’s lives. Product parts from stamping parts can be seen everywhere in life, ranging from the daily necessities commonly used in people’s lives to large parts such as aerospace. Metal stamping parts, since the use of metal stamping parts is so wide, what are the commonly used materials? 1. Hot-rolled steel sheet Hot-rolled steel is a high-quality carbon structural steel with a carbon mass fraction of 0.1%~0.15%. It belongs to low-carbon steel. Compared with cold-rolled steel sheet, hot-rolled steel sheet is cheaper. Thickness and high strength, so it has a wide range of applicability in the stamping field, especially in the automotive hardware stamping parts, hot-rolled steel plate occupies a considerable proportion, often used in beams, longitudinal beams, chassis structural parts, support parts and Manufacturing parts with higher formability requirements; 2. Cold-rolled steel sheets. There are many classification methods for cold-rolled steel sheets. According to the deoxidation method, they can be divided into boiling steel, killed steel and semi-killed steel; according to steel type and alloy composition, it can be divided into low carbon Steel, low-alloy high-strength steel, phosphorous steel, ultra-low-carbon non-interstitial atomic steel, etc.; according to the strength level, it can be divided into ordinary strength level and high strength level; according to the stamping level or use, it can be divided into general, stamping, and deep For stamping, extra-deep drawing, and ultra-deep drawing; 3. Stainless steel Stainless steel refers to a high-alloy steel with a mass fraction of chromium reaching more than 11%. Its main feature is that it has high corrosion resistance and heat resistance. Stainless steel and surface brightness, the stainless steel used in stamping and forming includes ferritic stainless steel, austenitic stainless steel and martensitic stainless steel. The stamping performance of ferritic stainless steel is close to that of cold-rolled steel sheet. In the production process of this kind of stainless steel, hot rolling, cold rolling and annealing methods can also be used to obtain the texture, which has good drawing performance. But its hardening index is about 92, and the elongation is 25%~30%, which are less than austenitic stainless steel, so its elongation type stamping performance is poor; among them, SUS430 can be used for stamping forming. Ferritic stainless steel and austenitic stainless steel represented by SUS304; 4. Coated steel plate is used to prevent corrosion of metal stamping parts by various acidic or alkaline air, moisture, water, oil and other substances. Japan and other countries have put forward the goal of five years of corrosion resistance on the surface of automobile bodies and ten years of resistance to perforation and corrosion, and have developed new coated steel plates. At present, most domestic automobiles also require the use of coated steel plates of different specifications and quantities; the resistance of the coated steel plate to powdering and peeling during stamping will affect its stamping formability. There are two types of coating peeling: the first is the formation of particles due to the internal failure of the coating, the particle size is generally smaller than the thickness of the coating, and it falls off in the form of powder, which is called chalking; the second is due to the failure of adhesion between the coating and the substrate. The size of the formed flake particles is generally similar to or larger than that of the plated metal. Quality is the foundation of the company. It is your choice. The daily output is 3 million strokes. It has 7 patents and 15 years of experience. ,support hotline:
