ASTM A387 Grade 9 Class 2 Plates
In industries where strength, heat resistance, and durability are critical, choosing the right alloy steel plate becomes essential. ASTM A387 Grade 9 Class 2 Plates are specifically designed for pressure vessels, boilers, and high-temperature service, making them a preferred choice across heavy engineering sectors.
Sai Steel & Engineering Company, a trusted name in alloy and pressure vessel steels, offers premium quality ASTM A387 Grade 9 Class 2 Plates that meet international standards and demanding industrial requirements.
What are ASTM A387 Grade 9 Class 2 Plates?
ASTM A387 Grade 9 Class 2 is a chromium-molybdenum alloy steel plate developed for elevated temperature applications. The presence of 9% chromium and molybdenum enhances oxidation resistance, creep strength, and corrosion resistance, especially in high-pressure environments.
Class 2 plates undergo heat treatment (normalized and tempered), resulting in superior mechanical properties compared to Class 1 plates.
