What is the use of steel coil and how to judge the material of 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 what the steel coil is used for. Only by knowing its purpose can we know where to use this kind of thing, and also look at how to judge the material of the steel coil.

　　What is the use of steel coils

　　Coated steel plate, the leading particle anti-scratch coating coating technology at home and abroad is used for curing, which is more than 5 times higher than the scratch resistance of general building panels, and can resist the scratching of sharper objects. It is mainly used in garage doors, rolling shutter doors and windows, home appliances and other fields. Special color-coated panels, which can cooperate with the heating principle of solar polysilicon, have excellent decoration and maintenance effects, and are widely recognized by the solar energy industry. The primary colors are pearlescent silver, golden yellow, and printed LOGO boards.

　　Colorful coated color steel coil is an extension of hot-dip galvanized steel coil. It is a deep-processed steel coil product produced by surface treatment of galvanized steel coil and then coating. It is suitable for further deep processing of cold-formed steel coil. It consists of cold-rolled steel coil base material, galvanized coating and coating. Because of its excellent weather resistance, formability and recyclability, it has become more and more a substitute for wood. The leading particle scratch-resistant coating coating coating coating technology at home and abroad is used for curing. The scratch resistance is more than 5 times higher than that of general construction boards, and it can resist the scratching of sharper objects. Mainly used in garage doors, rolling shutter doors and windows, home appliances and other fields.

　　How to judge the material of steel coil

　　Ordinary according to the amount of carbon C, divided into low carbon steel, high carbon steel, the most commonly used is 45 steel. All with the letter C, C45 belongs to medium carbon... other letters are based on the content of the elements, generally letters represent elements, numbers represent percentage content, low carbon boiling steel, generally can 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, 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. Commonly used in the manufacture of stamped parts and carburized parts, such as stamped products, sleeves, enamel products, automobile 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 (MPa): ≥ 295 (30)

　　Yield Strength (MPa): ≥ 175 (18)

　　Elongation delta 5 (%): ≥ 35

　　Sectional shrinkage rate ψ (%): ≥ 60 Easy-cutting steel products are widely used in: mechanical equipment: woodworking machinery, ceramic machinery, papermaking machinery, glass machinery, food machinery, construction machinery, plastic machinery, textile machinery, jacks, hydraulic presses, etc.;

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

　　According to the introduction of this article, I mainly tell you what the use of steel coils is. The article has written down its use for you. Although there are many types, the characteristics of each type are different. No matter what kind of use we choose, we must choose according to the use. In addition, we also clearly know how to judge the material of steel coils.
