API 5L Grade X65 or L450 PSL1 pipe is normal carbon steel material among the tree types and for common use, (None corrosion environment but in high pressure pipelines required a certain mechanical properties). so it has the highest content of C, Mn, Si, P, S than the other two types. (These chemical elements is lower the steel is purer).
