ASTM A516 Grade 70 steel plates are widely used for pressure vessel fabrication due to their excellent strength, toughness, and weldability. Here’s a concise overview based on their properties and applications:
Composition: A516 Gr.70 is a carbon steel with a typical composition of 0.27% carbon, 0.79-1.30% manganese, 0.13-0.45% silicon, and trace amounts of phosphorus and sulfur, ensuring good mechanical properties.
Properties: Offers high tensile strength (70-90 ksi), good yield strength (38 ksi min), and excellent notch toughness, making it suitable for low to moderate temperature environments.
Applications: Ideal for fabricating pressure vessels, boilers, and storage tanks, especially in industries like oil and gas, petrochemical, and power generation.
Weldability: Excellent weldability with standard processes, supporting efficient fabrication.
Standards Compliance: Meets ASME and ASTM standards, ensuring reliability for critical applications.
