Galvanized aluminum and magnesium steel plate is an alloy-coated plate among coated steel products. The mass fraction of metal elements in the coating is: 53% aluminum, 43% zinc, 2% magnesium, 1.5% silicon and other elements. The surface of the galvanized magnesium steel plate has a fine zinc flower texture formed by crystallization. The neatly arranged fine zinc flowers make the appearance of the coated product more natural and delicate. Galvanized aluminum and magnesium steel plate is a new type of highly corrosion-resistant coated steel plate. Its coating composition is mainly zinc, which is composed of zinc plus 1.5%-11% aluminum, 1.5%-3% magnesium and trace amounts of silicon (different manufacturers have proportions slightly different).

Aluminized steel plate is a steel plate plated with a layer of pure aluminum or an aluminum-silicon alloy containing 5% to 10% silicon on the surface of carbon steel. Aluminum plating methods include: hot plating, electrophoresis and vacuum evaporation, among which hot plating is the most widely used. Aluminized steel plates have good resistance to high-temperature oxidation and will not discolor for a long time at 450°C. The maximum use temperature can reach 750°C. It also has good resistance to atmospheric corrosion, especially corrosion resistance to SO2, H2S, CO2 and other gases. The corrosion resistance is 3 to 6 times that of galvanized steel plates. It is mainly used in automobile exhaust systems, heat-resistant appliances, beverage cans, etc.

Aluminum tube as a kind of high-strength duralumin, can be strengthened by heat treatment, in annealing, hardening and hot state of plasticity medium, spot welding weldability is good, with gas welding and argon arc welding aluminum tube has a tendency to form intergranular cracks; The machinability of aluminum tube is good after quenching and cold hardening, but poor in annealing state. Corrosion resistance is not high, often using anodic oxidation treatment and painting method or surface coated with aluminum layer to improve the corrosion resistance. Can also be used as a mold material.

304 stainless steel is the most common material in stainless steel. It is also called 18/8 stainless steel in the industry, which means it contains more than 18% chromium (Cr) and more than 8% nickel (Ni). It is widely used in the industrial and furniture decoration industries. Food and medical industry. In addition to the ordinary models, there are many extended models to adapt to various scenarios, such as low-carbon stainless steel 304L for occasions that require welding, nitrogen (N)-added stainless steel 304N to improve the strength of the steel, and high-temperature stainless steel to adapt to high-temperature environments. Stainless steel 304H.

430 stainless steel is a typical material of ferrite. It is also the most widely used and most used stainless steel among the 400 series stainless steel. It is also called stainless steel. As a representative steel type of ferrite, it contains 16%-18% chromium element, basically contains no nickel metal, and adds the stabilizing element titanium, so it is also called 18Cr stainless steel.

First of all, the price of raw materials is one of the important factors affecting the price of 304 stainless steel plates. The main components of 304 stainless steel plate are iron, chromium, nickel and other alloy elements. Price fluctuations of raw materials such as iron ore, chromium ore and nickel ore will directly affect the production cost of 304 stainless steel plates, thereby affecting their prices.

More Detail

The national standard brand of 304 stainless steel is: 06Cr19Ni10, and the national standard brand of 316 stainless steel is: 0Cr17Ni12Mo2. It can be simply recorded as, 304 is 8 nickel-18 chromium stainless steel, and 316 is 10 nickel 18 chromium stainless steel.
