In industries like power generation, oil & gas, and heavy engineering, choosing the right alloy steel plate is critical for strength, durability, and high-temperature performance. Among the widely used materials is SA 387 Gr.9 Cl.2, a chromium-molybdenum alloy steel plate known for its excellent heat resistance, corrosion resistance, and high strength, particularly in boilers, pressure vessels, and heat exchangers.
So how does it compare to other alloy steel plates?
Composition Differences
SA 387 Gr.9 Cl.2: Contains chromium and molybdenum, enhancing high-temperature strength and corrosion resistance.
Other Alloy Steel Plates: May have different ratios of chromium, nickel, or molybdenum, designed for specific applications such as wear resistance or impact strength rather than high-temperature service.
Property Differences
Heat Resistance: SA 387 Gr.9 Cl.2 excels at elevated temperatures, making it ideal for boilers and heat exchangers.
Strength & Hardness: Offers consistent strength under heavy loads, unlike some general-purpose alloy plates.
Corrosion Resistance: Better suited for harsh chemical or high-temperature environments.
Application Differences
While general alloy plates may be used for structural purposes, SA 387 Gr.9 Cl.2 is preferred for critical applications where safety, heat, and pressure tolerance are essential.
