5. Chemical Requirements

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%.

B Unless otherwise specified by the purchaser, 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 1.65%.

C These five elements combined shall not exceed 1%.

6. Mechanical Properties
Tensile Strength, min: 60ksi/415MPa
Yield Strength, min: 35ksi/240MPa

7. Manufacturing Process
Raw Material Inspection → Cold Centering → Heating → Piercing & Rolling → SIzing → Heat Treatment → Testing → Finishing → NDE → Visual & Dimension Inspection → Marking → Storing & Shipping

8. Heat Treatment
Hot-finished pipe need not be heat treated. Cold-drawn pipe shall be heat treated after the final cold draw pass at a temperature of 1200°F(650°C) or higher.

9. Supplementary Requirements
S1 Product Analysis
S2 Transverse Tension Test
S3 Flattening Test, Standard
S4 Flattening Test, Enhanced
S5 Metal Structure and Etching Test

The steel shall be homogeneous as shown by etching tests conducted in accordance with the appropriate sections of method E381. Etching tests shall be made on a cross section from one end or both ends of each pipe and shall show sound and reasonably uniform material free from injurious laminations, cracks, and similar objectionable defects, the length shall be rejected, subject to removal of the defective end and subsequent retests indicating the remainder of the length to be sound and resonably uniform material.
