Product description
ASTM A387 Grade 11 sheets and plates are premium chromium-molybdenum alloy steel products designed for high-temperature service. This grade, commonly known as 1-1/4 Cr - 1/2 Mo, offers exceptional resistance to high-temperature creep, oxidation, and thermal shock, making it the industry standard for critical pressure-retaining applications.
Key Features & Benefits
- Superior High-Temp Performance: Maintains mechanical integrity and strength at elevated temperatures, ideal for steam and hot oil services.
- Weldability & Formability: Excellent weldability facilitates the fabrication of complex structures and vessels with minimal distortion.
- Corrosion Resistance: Provides robust protection against atmospheric corrosion and high-temperature oxidation.
- Compliance: Manufactured strictly to ASTM A387 standards to ensure consistent quality and safety for pressure vessel applications.
Common Applications
These alloy steel plates are extensively used in the fabrication of pressure vessels, heat exchangers, boilers, reactors, and piping systems within the petrochemical, oil & gas, and power generation industries. They are the preferred choice for components exposed to high temperatures and pressures where carbon steel would fail.
