ASME SA 387 Grade 5 Class 1/2 Sheet and Plates are low alloy steel materials that contain between 4-6% chromium and 0.45-0.65% molybdenum, which significantly boost their ability to withstand high temperatures and resist corrosion. The carbon content is kept between 0.05% and 0.15%, along with controlled amounts of silicon, manganese, phosphorus, and sulfur. These plates are known for their impressive mechanical strength, boasting a tensile strength that ranges from 415 to 585 MPa and a yield strength starting at 240 MPa. Class 1 plates are recognized for their higher ductility, while Class 2 plates excel in tensile properties. They are commonly used in pressure vessels and heat exchangers, thanks to their reliability under thermal stress.
In the petrochemical, oil and gas, and power generation sectors, ASME SA 387 Grade 5 Class 1/2 Sheet and Plates are essential for high-temperature and high-pressure applications. These alloy steel plates are crucial for constructing boilers, heat exchangers, reactors, and pressure vessels due to their remarkable resistance to thermal fatigue and corrosion. Class 1 plates are typically selected for their formability and ductility, while Class 2 plates are favored in situations that demand higher tensile strength. Their excellent weldability and long-lasting durability make them vital for tough industrial settings that require consistent performance.
