Understanding ASTM A387 GR.91 CL.2 Plates
ASTM A387 GR.91 CL.2 plates are pressure vessel grade chrome molybdenum alloy steel plates used in various applications, including boilers and heat exchangers. These plates have a high amount of chromium and molybdenum, which makes them incredibly durable and resistant to corrosion and oxidation at elevated temperatures. They also have excellent weldability and formability due to their low carbon content, making them great for many projects.
These ASTM A387 GR.91 CL.2 Plates can be used in various applications, including construction, petrochemical plants, ships, pressure vessels, oil & gas production facilities, power plants, heat exchangers, boilers, etc. Additionally, they can also be used in chemical processing equipment as well as other industries where there is a need for highly durable materials such as cryogenic storage tanks or high-temperature process piping systems.
These plates have outstanding properties such as good formability even at elevated temperatures thanks to their low carbon content, allowing them to remain ductile while still providing excellent strength and toughness at normal and elevated temperatures up to 815°C (1500°F). It has exceptional weldability due to its low carbon equivalent value, making it an ideal choice for welding applications requiring good impact resistance, such as shipbuilding or offshore platforms where there is often a need for strong welds in harsh environments with corrosive fluids or gasses present at higher than normal temperatures like those found in steam generation plants or nuclear power plants.
The main benefit of using these plates is that they are very cost-effective compared to other alloys while still offering superior performance characteristics such as exceptional strength and toughness at higher than normal temperatures and excellent formability and weldability even at elevated temperatures up to 815°C (1500°F). This makes them an ideal choice for use in many projects, including those requiring strong welds that must withstand exposure to harsh environments with corrosive fluids or gasses present at higher-than-normal temperatures, like those found in steam generation plants or nuclear power plants.
