The quality of iron castings is evaluated through several testing methods:

  • Visual Inspection: To check for surface defects like cracks, porosity, or inclusions.
  • X-ray or Ultrasonic Testing: To detect internal defects or voids.
  • Hardness Testing: Measures the hardness of the casting, which relates to strength and wear resistance.
  • Tensile Testing: Assesses the strength of the material by pulling it apart until it breaks.
  • Dimensional Inspection: Ensures that the casting meets design specifications.
