A387 Gr 5 Cl 2 refers to ASTM A387 Grade 5 Class 2, which is a high-quality chromium-molybdenum Alloy steel plate primarily used in pressure vessel applications. Here are some key points about A387 Gr 5 Cl 2 steel:
Composition: A387 Gr 5 Cl 2 contains chromium (Cr), molybdenum (Mo), and other alloying elements such as manganese (Mn) and silicon (Si). The precise chemical composition ensures improved strength, corrosion resistance, and heat resistance.
Mechanical Properties: A387 Gr 5 Cl 2 offers excellent tensile strength, yield strength, and impact resistance at elevated temperatures. Typically, it has a minimum tensile strength of 75 ksi (515 MPa) and a minimum yield strength of 45 ksi (310 MPa).
Pressure Vessel Applications: A387 Gr 5 Cl 2 steel is commonly used for fabricating pressure vessels in industries such as oil and gas, petrochemical, and power generation. It is suitable for operating temperatures up to 600°C (1110°F) and exhibits good resistance to high-temperature hydrogen attack.
Heat Treatment: A387 Gr 5 Cl 2 is typically supplied in the normalized and tempered condition. This heat treatment process improves the material's toughness and makes it suitable for service under varying temperature and pressure conditions.
Weldability: A387 Gr 5 Cl 2 offers good weldability, enabling it to be easily welded using common welding methods such as SMAW (Shielded Metal Arc Welding), GTAW (Gas Tungsten Arc Welding), and SAW (Submerged Arc Welding).
Certification and Testing: A387 Gr 5 Cl 2 steel plates undergo rigorous testing and certification to ensure compliance with industry standards. These tests can include mechanical property testing, chemical analysis, impact testing, and non-destructive examination.
It's important to note that when using A387 Gr 5 Cl 2 steel or any other material for pressure vessel applications, it is essential to follow the applicable codes, regulations, and guidelines to ensure safe and reliable operation.
