ASTM A106 seamless pipes are used in the construction of oil and gas pipelines, power plants, petrochemical devices, boilers and ships building. ASTM A106 Gr.B is an American brand,consist of A,B and C three levels.106A means tensile strength 330 Mpa,B stands for 415 Mpa,then C is with high T/S @ 485Mpa.Among which the Gr.B is most common in supply and demand,

The chemical composition of A 106Gr.B is as follows:
1. C≤0.25
2. Mn=0.27-0.93
3. P≤0.035
4. S≤0.035
5. Si≤0.1
6. Cr≤0.4
7. Cu≤0.4
8. Mechanical properties: T/S ≥415／MPa , YS ≥240／MPa.
