A The sum of these five elements must not be greater than 1.00%。

B For every 0.01% decrease in the maximum carbon content, the maximum manganese content is allowed to increase by 0.06%, but the maximum cannot exceed 1.35%.

C Each 0.01% decrease in the maximum carbon content will allow the maximum manganese content to increase by 0.06%, but the maximum must not exceed 1.65%.

A The minimum elongation of gauge length 2in. (50mm) shall be determined by the following formula:

e=625000(1940)A0.2/U0.9

e = the minimum elongation of the gauge 2in. (50mm), the percentage rounded to the nearest 0.5%;

A = Calculated according to the specified outer diameter of the nominal tube or the nominal width of the tensile sample and its specified wall thickness, and rounded to the nearest cross-sectional area of the tensile sample of 0.01 in.2 (1 mm2), and It is compared with 0.75in.2 (500mm2), whichever is smaller.

U = specified minimum tensile strength, psi (MPa).

B For various combinations of different sizes of tensile test specimens and prescribed minimum tensile strength, the required minimum elongation is shown in Table X4.1 or Table X4.2, according to its applicability.

Test Requirement

Tensile test, bending test, hydrostatic test, nondestructive electrical test of welds.
