General Requirements for Delivery

Structural steel plates furnished under ASTM A572 shall comply with requirements of the current edition of Specification A6/A6M, for the specific structural product ordered, unless a conflict exists in which case this specification shall prevail.

Coils are not applicable to this specification until they are processed to a finished structural product. Structural steel plates produced from coil means they have been cut to individual lengths from a coil. The processor directly controls, or is responsible for, the operations involved in the processing of a coil into a finished structural product. Such operations include decoiling, leveling or straightening, hot-forming or cold-forming (if applicable), cutting to length, testing, inspection, conditioning, heat treatment (if applicable), packing, marking, loading for shipment, and certification.

A252 COMPARITIVE SPECIFICATIONS

ASTM Specification A252 describes nominal (average) wall steel pipe piles of cylindrical shape and applies to pipe piles in which the steel cylinder acts as a permanent load-carrying member or as a shell to form case-in-place concrete piles. Surface imperfections exceeding 25% of the nominal wall in depth are considered defects. Defects not exceeding 22.5% of the nominal wall in depth may be repaired by welding. Before welding, the defect shall be completely removed.

a. The deoxidation method is designated as follows: FF: Fully killed steel containing nitrogen binding elements in amounts sufficient to bind available nitrogen (e.g. min. 0,020 % total Al or 0,015 % soluble Al). b. The maximum value for nitrogen does not apply if the chemical composition shows a minimum total Al content of 0,020 % with a minimum Al/N ratio of 2:1, or if sufficient other N-binding elements are present. The N-binding elements shall be recorded in the Inspection Document.
