What is A588 Grade A corten steel coil mild steel

The company has allocated special environmental protection facilities for all A588 Grade A corten steel coil pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, A588 Grade A corten steel coil steel mill scale, environmental protection dust has reached 100%.

How much a ton of alloy plates costs depends on the classification of alloy plates. Different alloy plates contain different elements, such as low-alloy steel (the total amount of alloy elements is less than 5%), medium alloy steel (the total amount of alloy elements is 5% - 10%), and high alloy steel (the total amount of alloy elements is more than 10%). If the alloy plates performance is different, the price will be different. The thickness of the alloy plates also affects the price. Besides, A588 Grade A corten steel coil, alloy plates price is related to the steel market. With the rise of steel raw materials, the purchase cost will be high and the overall price will be high.

The boiler steel plate has small strain aging sensitivity, especially in the corresponding working temperature range, a certain value of aging impact energy must be guaranteed;The boiler steel plate has low notch sensitivity, which can prevent steel from cracking in welding, opening, and local stress concentration areas;The A588 Grade A corten steel coil, boiler steel plate has good welding performance;The A588 Grade A corten steel coil, boiler steel plate has a good microstructure, white spots and cracks are not allowed.

With the increase of carbon content in the steel material, the yield point and tensile strength increase, but the plasticity and impact decrease. When the carbon content is more than 0.23%, the welding performance of the steel material becomes worse. Therefore, the carbon content of low alloy structural steel used for welding is generally less than 0.20%. The high carbon content can also reduce the atmospheric corrosion resistance of steel material, and the high carbon steel in the open air is easy to rust; in addition, carbon can increase the cold brittleness and aging sensitivity of A588 Grade A corten steel coil etc. steel material.

According to GB 11251 technical standard, the chemical composition of 40Cr structural steel plate is as follow: Carbon content is 0.37-0.44 %, Silicon content is 0.17-0.37%, Manganese content is 0.50-0.80%, Chrome content is 0.80-1.10%. 40Cr steel is usually in shape of 40Cr steel plates and bars. A588 Grade A corten steel coil, GB 11251 is for 40Cr structural steel plate with thickness range of 4-30mm. The tensile strength of 40Cr structural steel plate is 550-800Mpa. And its min. Elongation is 16%.

Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our A588 Grade A corten steel coil products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.

After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
