There are many things that are essential in our daily life. No matter what we want to buy, we must first understand some knowledge. In this way, it will be easy to choose on the surface. Therefore, we can first look at the use of steel coils. Only when we know its use can we know where to use this kind of thing, and we also need to look at how to judge the material of steel coils.

What is the use of steel coil

The steel plate is coated with the leading particle anti-scratch coating skills at home and abroad for curing, which can enhance the scratch resistance of more than 5 times compared with the general construction plate, and can resist the scratch of sharp objects. Mainly used in garage doors, shutter doors and windows, home appliances and other areas. Special color coated board, can cooperate with the heating principle of solar polysilicon, has superior decoration effect and maintenance effect, and has been widely recognized by the solar energy industry. The primary color is pearlescent silver, golden yellow, printed LOGO board.

Colorful coated color steel coil is an extension of hot-dip galvanized steel coil. It is a kind of steel coil deep-processed product produced by applying coating to galvanized steel coil ahead of appearance treatment, which is suitable for further deep processing of cold bending forming. It is composed of cold rolled steel coil substrate, galvanized, coating three some. Because of its superior weather resistance and formability and recyclability, it is increasingly becoming a substitute for wood. The selection of domestic and foreign leading particle anti-scratch coating skills for curing, than the general construction plate scratch resistance can be enhanced by more than 5 times, can resist the more sharp objects of scratch. Mainly used in garage doors, shutter doors and windows, home appliances and other areas.

How to judge the steel coil material

Ordinary according to the amount of carbon-containing C, low carbon steel, high carbon steel, the most commonly used is 45 steel. All with the letter C,C45 is medium carbon... Other letters are based on the difference in the content of the elements, the general letter represents the element, the number represents the percentage content, low carbon boiling steel, generally can be replaced by 10 steel.

Characteristics and scope of application of 08F:

Its low strength, soft steel, good plasticity and toughness. General use does not require heat treatment, but in order to eliminate the internal force caused by cold working and improve the cutting performance of steel, heat treatment can be carried out, and cold working can increase the strength. Commonly used in the manufacture of stamping parts and carburizing parts, such as stamping products, sleeves, enamel products, automobile shells, etc.

1 chemical composition:

Carbon C:0.05~0.11

Silicon Si:≤ 0.03

Manganese Mn:0.25~0.50

Sulfur S:≤ 0.035

P:≤ 0.035

Chromium Cr:≤ 0.10

Nickel Ni:≤ 0.25

Copper Cu:≤ 0.25

2 Mechanical properties:

Tensile strength σb(MPa):≥ 295(30)

Yield strength σs(MPa):≥ 175(18)

Elongation δ5(%):≥ 35

Section shrinkage ψ(%):≥ 60 Easy-to-cut steel products are widely used: machinery and equipment: woodworking machinery, ceramic machinery, papermaking machinery, glass machinery, food machinery, construction machinery, plastic machinery, textile machinery, jacks, hydraulic presses Wait;

Electrical product components: motor shaft, fan shaft, sewing machine shaft, etc;

According to the introduction of this article, I mainly talked about the use of steel coil. The article has already written out its use. Although there are many types of steel coil, the characteristics of each type are different. No matter what kind of steel coil we want to use, we must choose according to the use. In addition, we also know clearly how to judge the material of steel coil.
