What Are A387 Grade 9 Class 2 Plates?
A387 Grade 9 Class 2 Plates is a chromium and molybdenum alloy steel plate that provides enhanced resistance to heat and oxidation. The "Grade 9" signifies 9% chromium content, which ensures improved corrosion protection, while molybdenum enhances tensile strength at elevated temperatures. The "Class 2" designation indicates higher mechanical strength compared to Class 1.
These plates are widely used for fabricating pressure vessels and boilers that operate under severe temperature conditions.
Key Features & Benefits
✔ Excellent High-Temperature Strength
These plates maintain structural integrity even at elevated temperatures, making them ideal for heat-intensive applications.
✔ Superior Corrosion & Oxidation Resistance
The high chromium content offers strong resistance to oxidation, sulphidation, and chemical degradation.
✔ Enhanced Weldability & Fabrication
A387 Gr 9 Cl 2 Plates can be easily formed, welded, and fabricated, ensuring smooth manufacturing processes.
