What are the Tianjin stainless iron hardware stamping parts factory + stamping materials?

by:Fortuna     2021-04-17
With the rapid development of society, the people's demand for stamping is increasing. So what raw materials do current stamping manufacturers use to produce stamping parts? In 15 years, Tianjin Stainless Iron Hardware Stamping Parts Factory 'Hardware' will take you to understand 1. Hot-rolled steel plate Hot-rolled steel is a high-quality carbon structural steel with a carbon mass fraction of 0.1%~0.15%, which belongs to low-carbon steel, Compared with cold-rolled steel plates, hot-rolled steel plates are cheaper, with higher plate thickness and strength, so they have a wider range of applicability in the stamping field, especially in the automotive hardware stamping parts, hot-rolled steel plates occupy a considerable amount It is often used for beams, longitudinal beams, chassis structural parts, supporting parts, and parts with high manufacturing formability requirements; 2. Cold-rolled steel plates There are many classification methods for cold-rolled steel plates, and they can be divided into boiling steel and sedated steel according to the deoxidation method. 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 grade and high strength grade ; According to the stamping level or use, it can be divided into general use, stamping use, deep drawing use, extra deep drawing use, ultra deep drawing use 3. Stainless steel refers to high alloy steel with a mass fraction of chromium reaching 11% or more. Its main It is characterized by high corrosion resistance and heat resistance, rust resistance 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 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 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 the plating layer. Tianjin Stainless Iron Hardware Stamping Parts Factory has focused on precision metal stamping for 15 years and has accumulated 50,000 sets of precision mold processing customization experience + stamping precision is as high as ± (positive/negative) 0.01mm, is the preferred partner of 15,000 companies worldwide. If you have stamping needs, Hardware looks forward to your call:
