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

We need to know the use of this kind of thing in our daily life. No matter where we buy it, we must know it first, We also need to see how to judge the material of steel coil.

What is the purpose of steel coil

Coated steel plate is cured by using the leading particle scratch resistant coating coating coating skills at home and abroad. The scratch resistance is more than 5 times higher than that of ordinary construction plates, and can resist the scratch of sharp objects. It is 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 and printed 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 consists 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. It is mainly used in garage doors, rolling shutter doors and windows, household appliances and other fields.

How to judge the material of steel coil

Ordinary steel is divided into low carbon steel and high carbon steel according to the content of carbon C. the most commonly used is 45 steel. They all have the letter C, and 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.
