Low-carbon steel plate is a kind of material with a large amount of use, which is divided into ordinary low-carbon steel plate and special steel plate, including low-alloy high-strength steel and corrosion-resistant and heat-resistant clad steel plate. Ordinary low-carbon steel sheets are divided into two types: cold-rolled and hot-rolled. Cold-rolled steel sheets have good surface quality and precise thickness and dimensions, and are mostly used in the manufacture of car bodies. Hot-rolled sheets are mostly used in the manufacture of frames and the like.Shanqi Steel specializes in the production of carbon steel products, has many years of production experience, manufactures with heart, and supports customization!
Classification of low carbon steel plates
According to the thickness, it is divided into: thick plate (above 6mm), medium and thick plate (3-6mm) and thin plate (below 3mm).
According to the process, it is divided into: cold-rolled steel plate, hot-rolled steel plate. Cold-rolled steel plates are generally used for parts that require a large degree of material deformation when forming parts, and there should be no wrinkles, cracks, etc. on the surface. For different parts, different grades of steel plates are used, such as: SPCC is a common cold-rolled steel plate, usually rolled by boiling steel; SPCD is a steel plate for rolling; SPCE or SPCEN is a cold-rolled steel plate for deep drawing.
Rotation of mild steel plate
The drawing and spinning test of a variety of low carbon steel sheets with different metallographic and mechanical properties was carried out, and the following points directly related to the spinnability were obtained.
a. The maximum elongation strain of aluminum-killed steel sheets of general purity exceeds 250% during deep-spinning.
b. The ultimate elongation of the boiling steel sheet with a slightly poorer purity decreases with the increase of the oxygen content of the steel sheet.
c. As soon as the grains of the steel sheet are coarsened, the forming limit decreases.
d. The total elongation, n value and r value in the mechanical properties of the steel sheet have no direct influence on the forming limit of spinning.
The steel plate used in the test is very thin (about 0.5mm), and the steel plate of common thickness (0.8-1.6mm) will definitely be much higher than the above extreme limit.
