ASME SA387 Grade 91 Class 2 Plates – High Quality Alloy Steel for High-Temperature Applications
Conquest Steel & Alloys is a leading manufacturer and supplier of ASME SA387 Grade 91 Class 2 Plates that are perfect to be used in high-temperature and pressure applications. The plates are designed with a chrome-moly-vanadium alloy content that provides superior creep strength, resistance to oxidation, and toughness under long-term stress.
SA387 GR.91 CL.2 steel plates are widely applied in boiler fabrication, heat exchanger fabrication, pressure vessel fabrication, and high thermal cycle exposed components. The chemical composition contains 9% Chromium and 1% Molybdenum along with Vanadium and Niobium additions, which provide increased mechanical strength and structural properties at temperatures above 600°C.
Every plate provided by Conquest Steel & Alloys is ASME and ASTM compliant with appropriate certifications and test reports. The plates are offered in tailor-made dimensions and thicknesses and are heat-treated (normalizing, tempering) for optimal performance and weldability.
We supply ASME SA387 Grade 91 Class 2 Plates that are dependable, consistent, and totally traceable, catering to high-critical industries such as power generation, refinery, petrochemical, and energy. Our products guarantee long-term safe operation even under the most challenging conditions.
