How to judge the material of galvanized steel coil

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 purpose of the steel coil. Only when we know its purpose can we know where to use this kind of thing. In addition, we should also look at the method of how to judge the material of the steel coil.

What is the purpose of steel coil

Coated steel plate is cured with the leading particle scratch resistant coating coating technology at home and abroad. Its scratch resistance is more than 5 times higher than that of the general construction plate, and it can resist the scratching of sharp objects. Mainly used in garage doors, rolling shutter doors and windows, home appliances and other fields. The special color coated plate, which can cooperate with the heating principle of solar polysilicon, has superior decoration and maintenance effects, and is 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. It is suitable for further deep-processing of cold bending forming. 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 advanced particle scratch resistant coating coating technology at home and abroad is used for curing, which can enhance the scratch resistance by more than 5 times compared with the general construction board, and can resist the scratching of sharp objects. Mainly used in garage doors, rolling shutter doors and windows, home appliances and other fields.

How to judge coil material

Ordinary steels are divided into low carbon steels and high carbon steels according to the content of carbon C. the most commonly used is 45 steel. Both have the letter C, and C45 is medium carbon... Other letters are distinguished according to the content of elements. Generally, letters represent elements, and numbers represent percentage content. Low carbon rimmed steels 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 generated by cold working and improve the cutting performance of steel, heat treatment can be carried out, and cold working can increase the strength. It is often used to manufacture stamping parts and carburized parts, such as stamping products, sleeves, enamel products, automobile shells, etc.
