What is the purpose of steel coil? How to judge the material of steel coil

Coated steel plate is cured by using the leading particle scratch resistant coating coating coating technology at home and abroad, which is more than 5 times higher than the scratch resistance of general construction plate, and can resist the scratch of sharp objects. Mainly used in garage doors, rolling shutter doors and windows, household appliances and other fields. The special color coated plate can cooperate with the heating principle of solar polysilicon, has excellent decoration effect and maintenance effect, and has been widely recognized by the solar energy industry. The primary color is pearlescent silver, golden yellow, printing logo board.

Colorful coated steel coil is an extension of hot-dip galvanized steel coil. It is a kind of steel coil deep-processing commodity produced by first treating the appearance of galvanized steel coil collar and then coating. It is suitable for cold bending forming and further deep-processing. It is composed of cold rolled steel coil base material, galvanizing and coating. Because of its superior weather resistance, formability and recyclability, it has increasingly become a substitute for wood. The leading coating technology of granular scratch resistant coating at home and abroad is selected for curing, which is more than 5 times higher than that of general construction board, and can resist the scratch of sharp objects. Mainly used in garage doors, rolling shutter doors and windows, household appliances and other fields.

How to judge coil material

Ordinary steels are divided into low carbon steel and high carbon steel according to the carbon content. The most commonly used is 45 steel. They all have the letter C. C45 belongs to medium carbon... Other letters are distinguished according to the content of elements. Generally, letters represent elements, numbers represent percentage content, and low-carbon boiling steel can generally be replaced by No. 10 steel.

Characteristics and application scope of 08F:

It has low strength, soft steel, good plasticity and toughness. Generally, heat treatment is not required, but in order to eliminate the internal force caused by cold machining and improve the cutting performance of steel, heat treatment can be carried out, and cold machining can increase the strength. It is often used to manufacture stamping parts and carburized parts, such as stamping products, sleeves, enamel products, automobile shell, etc.

1 Chemical Composition:

Carbon C: 0.05 ~ 0.11

Silicon Si: ≤ 0.03

Mn: 0.25 ~ 0.50

Sulfur s: ≤ 0.035

Phosphorus P: ≤ 0.035

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

Reduction of area ψ (%): ≥ 60 easy cutting steel products are widely used in: mechanical equipment: woodworking machinery, ceramic machinery, paper machinery, glass machinery, food machinery, construction machinery, plastic machinery, textile machinery, Jack, hydraulic press, etc;

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

According to the introduction of this article, we mainly talk about the purpose of steel coil. The purpose of steel coil has been written for you. Although it has many types, the characteristics of each type are different. No matter what kind of use we want to choose, we must choose according to the purpose. In addition, We also clearly know how to judge the material of steel coil.
