Compare API 5L X70 and sa 516-70?
Can someone compare these 2 materials and tell me the difference and if there is any similarities in between them, and which is stronger?
API 5L X70 steel is a high strength pipe material suitable for cross country pipeline applications. It is not as ductile or tough as ASTM A516-70 material which is a high quality fine grain plate steel used primarily for pressure vessels.
They are both carbon steel with the similar yield strengths but that is not the only measure of a material for a given application. Given a choice between the two, I would always choose the ASTM A516-70 material if possible.
