2. Technical requirements:
1). Chemical Composition:
Yield Strength Grade | Demotic Raw-material Grade |
235 | Q235B, Q235C, Q235D, Q235qC, Q235qD |
345 | Q345A, Q345B,Q345C,Q345D,Q345Qc, Q345Qd, StE355, B480GNQR |
Carbon Equivalent
Ceq(%)=C+Mn/6+Si/24 +Ni/40+Cr/5+Mo/4+V/14
Ⅰgrade product Ceq(%)
Yield Strength Grade | 235 | 345 | 390 |
Ceq(%) | ≤0.36 | ≤0.43 | ≤0.45 |
Note: In order to improve the performance of steel,390 could add the microelement such as V, Nb, Ti, Mo and N etc. |
2). Mechanical Property:
Yield Strength Grade | W.T (mm) | Yield Strength (Mpa) | Tensile Strength (Mpa) | Elongation (%) | (20°C) Impact Value J |
235 | 4~12>12~22 | ≥235 | ≥375 | ≥23 | ≥27 |
345 | 4~12>12~22 | ≥345 | ≥470 | ≥21 | ≥27 |
390 | 4~12>12~22 | ≥390 | ≥490 | ≥19 | ≥27 |
3). ⅠGrade Product Yield Strength:
Yield Strength Grade | Outside perimeter (mm) | Wall Thickness (mm) | Yield Strength % | |
Directly to Square | Round to Square | |||
235 | ≥800 | 12~22 | ≤80 | ≤90 |
345 | ||||
390 | ≤85 | ≤90 | ||
Note: when the outer perimeter less than 800mm,can be determined by supply and buyer |
3. Manufacturing Process:
1).Directly into Square: make continuous angle deformation of cold-rolled or hot-rolled steel plate directly, and then by high frequency welding form a rectangular steel tube forming method. Also known as square-square method.
2). Round to square: make continuous angle deformation of cold-rolled or hot-rolled steel plate directly, and then by high frequency welding form a round steel tube forming method, though the reshaping finally form a rectangular steel tube forming method. Also known as round to square method.
