ASME SA387 Grade 11 Class 1 Plates – High-Temperature Resistant Alloy Steel
Conquest Steel & Alloys is a leading name in the industry for providing high-quality ASME SA387 Grade 11 Class 1 Plates, made for high-temperature service in pressure vessels and boilers. These plates are from the chromium-molybdenum alloy group and possess very high strength, oxidation resistance, and thermal stability.
The SA387 GR.11 CL.1 plates are designed for use in moderate to high temperature and pressure resisting environments. With 0.5% molybdenum and 1.25% chromium, these plates ensure outstanding corrosion and oxidation resistance and are most suitable for the power plant, refinery, and chemical processing equipment fabrication.
At Conquest Steel & Alloys, we offer these plates in various sizes, thicknesses, and specifications as per ASME and ASTM standards. The material may also be customized with cut-to-size and third-party inspection reports upon request.
We conduct rigorous quality testing for all plates to ensure mechanical performance and durability even in harsh operating conditions. Where reliability, strength, and compliance are critical, our ASME SA387 Grade 11 Class 1 Plates are the go-to material.
