API 5L X65 PSL2 Yield strength conformation

Yield strength is a property that is generally specifed as a minimum to be met, not an exact number to be "hit."

If the API requirement is 600Mpa minimum YS, the material is compliant with the requirement. The higher the yield strength, the more force that the material will be able to withstand before permanently shanging its dimension,. Thats what Yield strength is.

LIke money, Good looking women, and interest rates on ones savings, More is better.

It ain't like Golf!

Why not look up what All those terms on that test report mean so you can have better understanding? Just google "yield strength, Ultimate tensile strength, % elongation, and % reduction in Area , separately, to learn what those numbers really mean?
