| A The total composition for these five elements shall not exceed 1.00 %. |
| B For each reduction of 0.01 % below the specified carbon maximum, an increase of 0.06 % of manganese above the specfied maximum will be permitted up to a maximum of 1.35 %. |

Mechanical Requirement
| Tensile Requirements |
|
|
| Mechanical Properties | Grade A | Grade B |
| Tensile strength, min, psi [MPa] | 48 000 [330] | 60 000 [415] |
| Yield strength, min, psi [MPa] | 30 000 [205] | 35 000 [240] |
| Elongation in 2 in. or 50 mm | A, B | A, B |
The minimum elongation in 2 in. [50 mm] shall be determined by the following equation:
e = 625000 [ 1940] A 0.2/U 0.9
Where:
e = minimum elongation in 2 in. or 50 mm in percent, rounded to the nearest percent,
A = the lesser of 0.75 in.2 [500 mm2] and the cross-sectional area of the tension test specimen, calculated using the specified outside diameter of the pipe, or the nominal width of the tension test specimen and the specified wall thickness of the pipe, with the calculated value rounded to the nearest 0.01 in.2 [1 mm2], and U = specfied minimum tensile strength, psi [MPa].
B See Table X4.1 or Table X4.2, whichever is applicable, for the minimum elongation values that are required for various combinations of tension test specimen size and specified minimum tensile strength. |
Steel Grades
Haotan offers ASTM A53 steel pipes in two distinct steel grades: Grade A and Grade B.You may require Furnace-butt welded continuous Welded Pipe (Type F), Electric Resistance Welded Pipe (Type E), or Seamless Pipe (Type S). Our steel grades are made to meet your needs.We use raw steel from an open-hearth furnace, electric furnace, or basic-oxygen process to ensure quality and consistency in every grade.Trust in our expertise to provide the right grade for your project.
