A387 Steel Plate
Introduction to A387 Alloy Steel Plate
The A387 steel plate is a high-quality chromium-molybdenum alloy steel specifically engineered for use in industries that require resistance to high pressure and elevated temperatures. It is widely used in the manufacturing of industrial equipment, pressure vessels, and boilers, particularly in oil and gas, petrochemical, and power generation sectors.
Chemical Composition of A387 Plate
The chemical composition of A387 steel plate makes it an ideal solution for high-temperature and high-pressure applications. Below is the standard range of its alloying elements:
The Role of Chromium and Molybdenum in A387 Alloy Steel
- Chromium (Cr)
Chromium is a key element in A387 alloy steel. It significantly improves the oxidation resistance, corrosion resistance, and high-temperature strength of the plate. In chromium-molybdenum grades, Cr enhances durability under harsh thermal environments, making it suitable for pressure vessels and heat exchangers.
- Molybdenum (Mo)
Molybdenum enhances the thermal strength and mechanical properties of A387 steel. It also increases creep resistance, tensile strength, and resistance to corrosive gases. Mo helps the plate retain its mechanical performance even in prolonged exposure to extreme heat and pressure.
The combination of chromium and molybdenum allows the A387 plate to deliver reliable performance in critical temperature ranges, ensuring long service life and safety.
