API 5L Gr.B/L245 steel vs A106 Gr.B steel for seamless pipes steel plate

API 5L Gr.B/L245 steel plate meaning: The two digit number following the "X" indicates the Minimum Yield Strength (in 000's psi) of pipe produced to this grade.  X42 has the minimum yield strength of 42 kilopound/square inch and X52 has the 52 ksi.
ASTM A106 pipe is the standard specification for A106 Gr.B seamless carbon Steel pipe for high-temperature and pressures service.
API 5L standard has PSL1 and PSL2 two product specifications, they are different on chemical composition, manufacturing processes, mechanical strength, heat treatment, test records, traceability etc. Below is the API 5L PSL1 X42 steel technical requirements.
