What are the uses of steel coils

Coating steel plates, using advanced particle scratch resistant coating techniques at home and abroad for curing, enhances the scratch resistance of general construction boards by more than 5 times, and can resist scratches from sharp objects. Mainly used in the fields of garage doors, rolling shutter doors and windows, household appliances, etc. Dedicated color coated panels, which can cooperate with the heating principle of solar polycrystalline silicon, have excellent decoration and maintenance effects, and are widely recognized in the solar energy industry. The primary colors are pearlescent silver, golden yellow, and printed with a logo board.

Colorful coated color steel coil is an extension product of hot-dip galvanized steel coil. It is a steel coil deep processing product produced by first treating the surface of the galvanized steel coil collar, and then applying paint. It is suitable for cold bending forming and further deep processing. It consists of three parts: cold-rolled steel coil substrate, galvanizing, and coating. Because of its superior weather resistance, formability, and recyclability, it is increasingly becoming a substitute for wood. Using advanced particle scratch resistant coating techniques both domestically and internationally for curing, it enhances the scratch resistance of general construction boards by more than 5 times and can resist the scratching of sharp objects. Mainly used in the fields of garage doors, rolling shutter doors and windows, household appliances, etc.

How to judge the material of steel coils

According to the difference in carbon content, ordinary steel can be divided into low carbon steel, high carbon steel, and the most commonly used is 45 steel. Both have the letter C, and C45 belongs to medium carbon... The other letters are based on the content of the elements. Generally, letters represent elements, and numbers represent 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 to eliminate internal forces caused by cold working and improve the cutting performance of steel, heat treatment can be carried out, which can increase strength. Commonly used in the manufacturing of stamped and carburized parts, such as stamped products, sleeves, enamel products, automotive 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

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

Reduction of area ψ (%): ≥ 60 easy to cut steel products are widely used in mechanical equipment such as woodworking machinery, ceramic machinery, papermaking machinery, glass machinery, food machinery, construction machinery, plastic machinery, textile machinery, jacks, hydraulic machines, etc;

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

According to the introduction of this article, we mainly talked about the purpose of steel coils. The article has already written down its purpose for everyone. Although there are many types of steel coils, the characteristics of each type are different. Regardless of what type to choose for use, we must choose according to the purpose. In addition, we also have a clear understanding of how to determine the material of steel coils.
