The wear-resistant steel plate is composed of low-carbon steel plate and alloy wear-resistant layer, which is generally 1/3~1/2 of the total thickness. When working, the matrix provides comprehensive properties such as strength, toughness and plasticity to resist external forces, and the alloy wear-resistant layer provides wear-resistant properties that meet the requirements of specified working conditions.
The purpose of electro galvanization is to prevent steel objects from being corroded, improve the corrosion resistance and service life of steel, and also increase the decorative appearance of products. Steel will be corroded by weathering, water or soil with the increase of time. In China, the corroded steel accounts for almost one tenth of the total steel volume every year.
Round steel is a long solid steel with a circular cross-section. Its specification is expressed in diameter, unit millimeter (mm), such as “50mm” that means the diameter of 50 mm round steel.
Galvanized iron wire is also divided into hot galvanized wire and cold galvanized wire (electric galvanized wire), which is made of high quality low carbon steel, after drawing, pickling and rust removal, high temperature annealing, hot galvanizing. Cooling and other processes.
Spiral welded pipe: It is made of low-carbon carbon structural steel or low-alloy structural steel strip rolled into a pipe billet at a certain angle of the spiral line (called forming angle), and then the pipe seam is welded together, which can produce large diameter steel pipe from narrower strip steel. Its specification is expressed by the outer diameter * wall thickness, welded pipe should ensure that the hydraulic test, tensile strength of the weld and cold bending properties to meet the provisions.
Galvanized coil is very popular in the market because of its economy. Compared with other steels, galvanized steel plate has good anti-corrosion effect and high application value. It has a wide range of applications. The world’s zinc output is generally used for processing galvanized sheet. Due to the high market popularity, the galvanized sheet needs to be processed. This figure is particularly large. Galvanized steel sheet generally includes hot-dip galvanized steel sheet, alloy galvanized steel sheet, galvanized steel sheet, single-sided galvanized steel sheet and double-sided galvanized steel sheet. Due to different production and processing methods, these typical galvanized sheets are also used in different places.
