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 case, it will be easy to choose on the surface. Therefore, we can first look at the What is the use of steel coils? Only when you know its use can you know where to use this kind of thing, and also look at how to judge the material of steel coils.

What is the use of steel coils

The steel plate is coated with leading particle scratch-resistant paint coating technology at home and abroad for curing, which is more than 5 times stronger than the scratch-resistant performance of general building boards, and can resist the scratching of sharper objects. It is mainly used in garage doors, rolling shutter doors and windows, home appliances and other fields. Special color-coated panels can cooperate with the heating principle of solar polysilicon, have excellent decoration effects and maintenance effects, and are widely recognized by the solar energy industry. The primary colors are pearlescent silver, golden yellow, and printed LOGO boards.

Colorful coated color steel coil is an extension product of hot-dip galvanized steel coil. It is a deep-processed product of steel coil produced by surface treatment of galvanized steel coil and then coating. It is suitable for further deep-processing by cold-rolled forming. It is composed of cold-rolled steel coil base material, galvanized and coated. Because of its superior weather resistance, formability and recyclability, it has become more and more a substitute for wood. It is cured by using leading particle scratch-resistant coating coating technology at home and abroad, which is more than 5 times stronger than the scratch resistance of general construction boards, and can resist the scratching of sharper objects. Mainly used in garage doors, rolling shutter doors and windows, home appliances and other fields.

How to judge the material of steel coil

Ordinary according to the amount of carbon C, divided into low carbon steel, high carbon steel, the most commonly used is 45 steel. All with the letter C, C45 belongs to medium carbon... The other letters are based on the content of the elements. Generally, the letters represent the elements, and the numbers represent the percentage content. Low-carbon boiling steel can generally be replaced by No. 10 steel.

Characteristics and scope of application of 08F:

It has low strength, soft steel, good plasticity and toughness. Generally, heat treatment is not required for use, but in order to eliminate the internal force generated 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 stamped parts and carburized parts, such as stamped products, sleeves, enamel products, car casings, etc.

1 Chemical composition:

Carbon C: 0.05~ 0.11

Silicon Si: ≤ 0.03

Manganese Mn: 0.25~ 0.50

Sulfur S: ≤ 0.035

Phosphorus P: ≤ 0.035

Chromium Cr: ≤ 0.10

Nickel Ni: ≤ 0.25

Copper Cu: ≤ 0.25

2 Mechanical properties:

Tensile strength σ b (MPa): ≥ 295 (30)

Yield strength σ s (MPa): ≥ 175 (18)

Elongation δ 5 (%): ≥ 35

Section shrinkage rate (%): ≥ 60 Easy-cutting steel products are widely used in: mechanical equipment: woodworking machinery, ceramic machinery, papermaking machinery, glass machinery, food machinery, construction machinery, plastic machinery, textile machinery, jacks, hydraulic press, etc.;

Electrical product parts: motor shaft, fan shaft, sewing machine shaft, etc.;

According to the introduction of this article, I mainly tell you what the use of steel coils is. The article has written its use for you. Although there are many types, the characteristics of each type are different. Yes, no matter what kind of use we want to choose, we must choose according to the use. In addition, we also clearly know how to judge the material of the steel coil.
