SA 516 Grade 70 is a carbon steel material primarily used in the fabrication of pressure vessels and boilers. It is commonly used for plates, but when you ask about a "pipe equivalent," you're likely looking for a material that offers similar mechanical properties and usage in piping applications.
The closest equivalent to SA 516 Grade 70 for piping would be ASTM A106 Grade B or ASTM A53 Grade B. Both of these materials are carbon steel and are commonly used for pipes that are subjected to high temperatures and pressures, similar to the applications where SA 516 Grade 70 is used for plates.
ASTM A106 Grade B: Used for seamless carbon Steel pipe for high-temperature service.
ASTM A53 Grade B: Used for welded and seamless steel pipe for low to moderate pressure applications.
These materials provide similar tensile strength and ductility characteristics, making them suitable equivalents for piping applications where SA 516 Grade 70 might be used for plate applications.
