The chemical composition of A387 Grade 11 Class 1 steel plate mainly includes carbon (C): 0.05~0.17%, silicon (Si): 0.5~0.8%, manganese (Mn): 0.4~0.65%, chromium (Cr): 1.0~1.5% , Molybdenum (Mo): 0.45~0.65%, Phosphorus (P): ≤0.25%, Sulfur (S): ≤0.035%. The proportion and control of these elements play a key role in the manufacturing process of steel plates, affecting their mechanical properties and corrosion resistance.
A387 Grade 11 Class 1 (often abbreviated as SA387Gr11CL1) steel plate has a wide range of specific uses, especially in equipment manufacturing under high temperature and high pressure environments. It is often used in the manufacturing of key equipment, such as boilers and pressure vessels, in petroleum, chemical, electric power and other industries.
Specifically, SA387Gr11CL1 steel plate plays an important role in the manufacturing of the following equipment and engineering components:
Petroleum and chemical equipment: used to manufacture reactors, heat exchangers, separators and other equipment. These equipment often need to withstand high temperature, high pressure and corrosive media, and the excellent performance of SA387Gr11CL1 makes it an ideal choice.
Power station equipment: In power stations, SA387Gr11CL1 steel plates are often used to manufacture key components such as boiler drums and reactor pressure shells of nuclear power plants. These components need to withstand high temperatures, high pressures and strong radiation environments.
Liquefied gas tanks and oil and gas tanks: Due to its good corrosion resistance and strength, SA387Gr11CL1 is also often used to manufacture liquefied gas tanks, oil and gas tanks and other storage equipment to ensure that the equipment can maintain stable performance during long-term use.
Other equipment: In hydropower stations, SA387Gr11CL1 is used to manufacture high-pressure water pipes, turbine volutes and other equipment; this steel plate is also widely used in the manufacture of liquefied petroleum gas bottles.
In short, SA387Gr11CL1 steel plate performs well in high temperature, high pressure and corrosive environments due to its excellent high temperature strength, oxidation resistance and sulfide corrosion resistance, and is widely used in the manufacturing of various equipment and engineering components.
