How to determine the material of steel coil? What are the uses of steel coils?

In our daily life there are many things are essential, we do not care what we want to buy, we must first understand some knowledge, in this case, but the face of the choice will be easy, therefore, we can first look at what is the use of steel coils, only clear its use can know where to use this kind of thing, and, also, how to judge the steel coil material method.

What is the use of steel coil

Coated steel plate, the selection of domestic and foreign leading particles of anti-scratch coating coating skills for curing, than the general construction of the plate anti-scratch performance enhancement of more than 5 times, can resist the scraping of the sharper objects. It is mainly used in garage doors, rolling doors and windows, home appliances and other categories. Special color coated panels, can cooperate with solar polysilicon heating principle, have superior decoration effect and maintenance effect, widely recognized by the solar industry. The primary colors are pearlescent white silver, golden yellow, printed LOGO plate.

Colorful coating color steel coil is hot-dip galvanized steel coil extension commodities, is the galvanized steel coil leading line appearance treatment, and then coated with paint and produced a steel coil deep processing commodities, suitable for cold-formed for further deep processing. It consists of cold rolled steel coil substrate, galvanized, coated with three components. Because of its superior weather resistance and moldability and recyclability, it is increasingly becoming a substitute for wood. Selected domestic and foreign leading particles of anti-scratch coating coating skills for curing, than the general construction of the board anti-scratch performance enhancement of more than 5 times, can resist the scraping of the sharper objects. Primary application in the garage door, rolling doors and windows, home appliances and other categories.

How to judge the steel coil material

Ordinary according to the difference between the amount of carbon C, low carbon steel, high carbon steel, the most commonly used is 45 steel. All with the letter C, C45 belongs to the middle carbon ... other letters of the letter is based on the content of the elements in which the difference, the general letter on behalf of the elements, the number represents the percentage of content, low carbon boiling steel, you can generally use the No. 10 steel to replace.

Characteristics and scope of application of 08F:

Its low strength, soft steel, good plasticity and toughness. General use does not require heat treatment, but in order to eliminate internal forces due to cold working and improve the cutting performance of the steel, can be heat-treated, cold working can increase the strength. Commonly used in the manufacture of stamped parts and carburized parts, such as stamping products, sleeves, enameled products, automobile shells.
