Macrostructure
Specimens for the determination of the macrostructure shall represent the entire cross-sectional area in the annealed condition and be prepared in accordance with the latest issue of Practice A561. Material supplied to this specification shall be capable of exhibiting a structure free of excessive porosity, segregation, slag, dirt or other nonmetallic inclusions, pipe, checks, cracks, and other injurious defects.
Macroetch severity levels for center porosity and ingot pattern, illustrated photographically in Practice A561, shall not exceed the ratings specification in Table 4 in ASTM A681 for the appropriate material size and composition. More stringent requirements are available by agreement between seller and purchaser.
Decarburization
Specimens for the determination of decarburization shall represent a cross section of the material and be prepared in accordance with the latest issue of Guide E3. Material supplied to this specification shall be capable, when examined at 20 times or greater magnification, of not exceeding the values given in Tables 5-8 for the appropriate size and shape of material. Lower limits of decarburization may be specified by agreement between the seller and purchaser.
Material ordered as ground and polished or ground finished or machine finished shall be free of scale and decarburization.
Workmanship, Finish, and Appearance
All alloy tool steels shall be free of heavy scale, deep pitting, laps, porosity, injurious segregations, excessive nonmetallic inclusions, seams, cracks, checks, slivers, scale marks, dents, soft and hard spots, pipes, or any defects that would detrimentally affect the suitability of the material after removal of the recommended stock allowance.
