What are ASTM A387 GR 22 CL 2 Plates?
ASTM A387 GR.22 CL.2 plates are made from alloy steel that is designed to resist corrosion in harsh environments and temperatures ranging from -20°F to 1400°F (-29°C to 760°C). This alloy is composed of chromium molybdenum and silicon with a nominal composition of 0.50% carbon, 0.45% manganese and 0.15% silicon (balanced by iron). The alloy also contains small amounts of other elements, such as sulfur, phosphorus, and nitrogen, which add additional strength to the material without compromising its ductility or toughness properties at elevated temperatures or pressures up to 4800 psi (330 bar).
Features of ASTM A387 GR.22 CL.2 Plates
ASTM A387 GR.22 CL 2 Plates offer excellent strength and high heat resistance thanks to their low carbon content, which protects against high-temperature oxidation, creep deformation, thermal shock, and stress corrosion cracking (SCC). The plates also feature superior wear resistance compared to other alloys due to their higher chromium content which forms a protective oxide layer on the surface of the plate when exposed to oxygen in the atmosphere or air at elevated temperatures as well as when submerged in water or oil environments up to 1200°F (650°C). Additionally, these plates have good weldability due to their low levels of carbon, which helps prevent hot cracking during welding operations on thicker sections of plate material where preheat may be required for certain ASME code welding processes such as those involving pressure vessels or structural components subject to torsional loading requirements under API 6A specifications for offshore drilling rigs operating in deep-water environments where extreme temperatures may occur due to geothermal activity below the ocean floor.
Applications of ASTM A387 GR 22 CL 2 Plates
Due to its strong mechanical properties and heat resistance characteristics, ASTM A387 GR 22 CL 2 plates are used in many industries including shipbuilding and offshore structures; boilers; chemical processing plants; power plants; construction equipment; heavy machinery; mining equipment; storage tanks; valves; pumps; bridges; pipelines; conveyor systems; nuclear reactors etc. Another common application for these plates is for industrial ovens where there may be extreme temperature conditions that require continuous operation over long periods of time with minimal maintenance necessary on a regular basis due some form of catastrophic failure event such as fire damage or overheating caused by an electrical short circuit occurring inside the oven enclosure structure itself resulting in potential product contamination issues that could cause serious health safety concerns if not properly addressed prior to use by end users who might come into contact with any residual contaminants left behind after cleaning has been completed post event.
