Concept
A516 Grade 70 is a carbon steel plate designed for pressure vessel applications, adhering to the ASTM A516 standard. Known as a pressure vessel quality (PVQ) steel, it excels in moderate and lower-temperature environments, offering superior notch toughness and weldability. This grade is widely regarded for its reliability in high-pressure systems.
Dimensions
A516 Grade 70 is available in various sizes to suit industrial needs. Plates typically range from 2 mm to 150 mm in thickness, 600 mm to 3000 mm in width, and 6000 mm to 12,000 mm in length. Custom dimensions can be supplied based on specific requirements, ensuring flexibility for diverse projects.
Chemical Composition
The steel’s composition includes:
Carbon (C): 0.27% max, for strength.
Manganese (Mn): 0.85-1.20%, enhancing toughness.
Phosphorus (P): ≤0.035%, minimizing brittleness.
Sulfur (S): ≤0.035%, improving ductility.
Silicon (Si): 0.15-0.40%, boosting elasticity.
This blend ensures durability and performance under stress.
Application Range
A516 Grade 70 is extensively used in the oil, gas, and petrochemical industries for fabricating boilers, pressure vessels, and storage tanks. Its ability to withstand moderate temperatures and pressures makes it ideal for power generation plants and chemical processing equipment. Additionally, it supports applications like bridges and structural components requiring robust, weldable steel.
In summary, A516 Grade 70 is a versatile, high-quality steel plate integral to industrial infrastructure worldwide.
