What are the metal stamping parts processing plants around Zhengzhou + stamping raw materials?

The hardware stamping parts needed for new products, but what are the raw materials of general stamping parts? Which materials are reliable? Hardware stamping parts processing factories around Zhengzhou tell you what raw materials are used for custom processing of metal stamping parts! What are the stamping raw materials for metal stamping parts? 1. Hot-rolled steel plate Hot-rolled steel is a high-quality carbon structural steel with a carbon mass fraction of 0.1% to 0.15%. It is a low-carbon steel. Compared with cold-rolled steel plate, Hot-rolled steel plates are cheaper, thicker and stronger, so they have a wider range of applicability in the stamping field, especially in automotive hardware stamping parts. Hot-rolled steel plates account for a considerable proportion, and are often used in beams and longitudinals. Beams, chassis structural parts, supporting parts and parts with high manufacturing 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; Steel grade and alloy composition 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 stamping level or purpose It is divided into general use, stamping use, deep drawing use, extra deep drawing use, and ultra deep drawing use; 3. Stainless steel refers to high alloy steel with a chromium content of more than 11%. Its main feature is that it has a high Corrosion resistance and heat resistance, rust resistance and surface brightness, 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 the corrosion of metal stamping parts by various acidic or alkaline air, moisture, water, oil and other substances. The United States, 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 they 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 plating layer.
