Mechanical properties of 40NCD7 40NiCrMo7 forged bars shall be determined on specimens machined from a pancake forging or prolongation thereof, which has been forged and heat treated with the balance of the forgings it represents.
The specimens shall be taken at mid-radius of the forging cross-section in a tangential orientation, and centrally located between the parallel faces of the pancake forging. Prolongation tensile and/or Charpy specimens shall be similarly oriented and adjacent to the section-face per technical manual
Mechanical property tests are to be conducted in accordance with ASTM A370, latest edition.
Standard ASTM 1/2 inch (13 mm) diameter tensile test specimens shall be used when the dimensions of the test material permit; in other instances, a sub-size specimen as defined in ASTM A370 may be used.
QUALITY REQUIREMENTS of 40NCD7 40NiCrMo7 forged parts
Forgings shall be free from cracks, seams, laps, shrinkage and other injurious
imperfections which, due to their nature or degree, would prevent fulfillment of the physical or mechanical requirements of the part.
The finished forging shall be magnetic particle inspected in accordance with ASTM A275, latest edition, and procedure ASTM E709, latest edition,
using the fluorescent method, and shall meet acceptance criteria as defined in Standard 21,125-00.
Ultrasonic inspection of the forging shall be conducted in accordance with the latest edition of ASTM A388, and shall meet acceptance criteria as defined in Standard 21,306-00.
