ASTM A516 Gr 70 is a type of steel plate that is commonly used in pressure vessels, boilers, and other high-pressure applications. Here are some key properties and characteristics of ASTM A516 Gr 70 steel: - Grade: ASTM A516 Gr 70 - Material: Carbon Steel - Thickness: 4mm-150mm - Width: 1000mm-3000mm - Length: 3000mm-12000mm - Yield Strength: 70 ksi (485 MPa) - Tensile Strength: 90 ksi (620 MPa) - Elongation: 17% (min) - Impact Test: -20°C (optional) - Heat Treatment: Normalized ASTM A516 Gr 70 steel is known for its: - High strength and toughness - Good weldability and machinability - Good corrosion resistance - Affordable price Applications: - Pressure vessels - Boilers - High-pressure equipment - LPG cylinders - Nuclear reactor components Note: ASTM A516 is a specification from the American Society for Testing and Materials (ASTM), and Gr 70 is the grade level. The exact composition and properties of ASTM A516 Gr 70 steel may vary depending on the specific standard or specification being followed. However, it is generally considered to be equivalent to other international steel standards such as EN 10028 P265GH and GOST 23500 St45-3.
