Product Information
API 5L PSL2 Gr.B grade designations come from API Spec 5L Specification for Line Pipe. Stronger grades have the designation X followed by the specified minimum yield strength of the pipe steel, measured in kilopounds per square inch (abbreviated ksi). Standard Line Pipe has grade designation A and B.
Chemical composition(%)
| Standard | Grade | ||||
| API 5L | Gr.b | C | Mn | P | S |

Mechanical requiremnts
| Grade | Yield Strength (Mpa) | Tensile Strength (Mpa) |
| API 5L GR.B | 245-450 | 415-760 |
Note: Line pipe mechanical testing usually omits Reduction of Area (RA) measurement reporting, and Charpy V-Notch (CVN) testing. This prevents use of this pipe as body material above 36 ksi yield strength for API Spec 6A equipment without retesting for Reduction of Area, and in the case of low temperature service, Charpy V-Notch testing as well.
0.50% maximum for copper, 0.50% maximum for nickel, 0.50% maximum for chromium, and 0.15% maximum for molybdenum.
For each reduction of 0.01% below the specified maximum concetration for carbon, an increase of 0.05% above the specified maximum concentration for manganese is permissible, up to a maximum of 1.65%.
Unless otherwise agreed, the sum of the niobium and vanadium contents shall be <=0.06%.
The sum of the niobium ,vanadium and titanium concentratons shall be <=0.06%.
