    Main Grade

    Grade of high-quality carbon boiler steel: GrA, GrC

    Chemical Component

    Element Grade A Grade C
    C ≤0.27 ≤0.35
    Mn ≤0.93 0.29-1.06
    P ≤0.035 ≤0.035
    S ≤0.035 ≤0.035

    A For each reduction of 0.01 % below the specified carbon maximum, an increase of 0.06 % manganese above the specified maximum will be permitted up to a maximum of 1.35 %.

    Mechanical Property

    Grade A Grade C
    Tensile Strength ≥ 415 ≥ 485
    Yield Strength ≥ 255 ≥ 275
      Elongation rate ≥ 30 ≥ 30

    Test Requirement

    Hydraustatic Test:

    The Steel Pipe Should Be Tested Hydraulically One By One. The Maximum Test Pressure Is 20 MPa. Under The Test Pressure, The Stabilization Time Should Be Not Less Than 10 S, And The Steel Pipe Should Not Leak.

    After The User Agrees, The Hydraulic Test Can Be Replaced By Eddy Current Testing Or Magnetic Flux Leakage Testing.

    Flattening Test:

    Tubes With An Outer Diameter Greater Than 22 Mm Shall Be Subjected To A Flattening Test. No Visible Delamination, White Spots, Or Impurities Should Occur During The Entire Experiment.

    Flaring Test:

    According To The Requirements Of The Purchaser And Stated In The Contract, The Steel Pipe With Outer Diameter ≤76mm And Wall Thickness ≤8mm Can Be Done Flaring Test . The Experiment Was Performed At Room Temperature With A Taper Of 60 °. After The Flaring, The Flaring Rate Of The Outer Diameter Should Meet The Requirements Of The Following Table, And The Test Material Must Not Show Cracks Or Rips

    Hardness Test:

    Brinell or Rockwell hardness tests shall be made on specimens from two tubes from each lot
