What is the difference between marine steel plate AH32 and AH36? AH36, H stands for high strength 36 stands for 360MPa and A stands for the grade of steel, which can be divided into 4 grades (Grades A, B, D, E). Therefore, the meaning of this code is high-strength Grade A marine steel with allowable pressure of 360MPa. AH32 steel plate is high-strength Grade A marine steel with a required pressure of 320map! There is no substitute for the difference!"
Steel logistics takes “steel” as the carrier, “logistics” as the operation, and “information” as the core. It integrates steel trade, e-commerce, and tripartite logistics as one. The flow of funds, information, and logistics promote each other and integrate with each other. Construction industry, metallurgy industry, information industry, modern logistics cross-industry. Our logistics service team will make sure our goods delivered to the leaving port on time.Makes you worry-free after sales.
The tempering of ah36 DH36 EH36 steel plate steel plate, the hardened steel will be reheated to a certain temperature, and then a certain method of cooling is called tempering.Its purpose is to eliminate the internal stress caused by quenching, reduce hardness and brittleness, so as to achieve the desired mechanical properties. Tempering is divided into three types: high temperature tempering, medium temperature tempering and low temperature tempering.Tempering and quenching, with the use of normalizing.
Compared with the traditional seamless steel pipe, alloy seamless pipe has better performance in all aspects. Because of the addition of various metal elements in the manufacturing, the overall strength of the alloy seamless pipe is larger, stronger and durable, and the service performance and service life of the ah36 dh36 eh36 steel plate, alloy seamless pipe are improved. The alloy seamless pipe is the best choice especially for special environment and high pressure requirements. Because of its high material properties, alloy seamless pipe has good corrosion resistance. It is not easy to be corroded in some special environment, which reduces the cost of the project and has a longer service life.
