ASTM Standard:

• A20/A20M: Specification for General Requirements for Steel Plates for pressure Vessels
• A435/A435:  Ultrasonic Examination Specification for Straight-Beam  of Steel Plates
• A577/A577M: For Ultrasonic Angle-Beam Examination of Steel Plates
• A578/A578M: For Straight-Beam Ultrasonic Examination of Rolles Steel Plates for Special Applications

General Requirements and Ordering Information

The plates shall confirm to ASTM A20/A20M.

• Testing and retesting methods, procedures;
• Permissible tolerances in dimensions and mass, quality;
• Repair of defects;
• Marking, loading and ordering information;
• Coils are excluded from this specifcation in case cutted to the plates form.

Material and Manufacture
The steel shall be killed and made to a coarse austenitic grain size practice.

Heat Treatment
ASTM A515 plates thickness in 50 mm [2 inch] thickness and under are normally supplied with as-rolled condition, unless it is ordered as requested.
Plates over 50 mm [2 in] in thickness shall be normalized.
