About This Item
ASTM E446 is a reference standard for evaluating steel castings up to 2 in. (50.8 mm) in thickness using radiographic comparison materials. It helps provide a consistent visual basis for assessing casting quality, which is important when comparing indications and supporting acceptance decisions. Built around the official ASTM standard title, ASTM E446 is a practical tool for inspection teams, quality programs, and procurement documents that rely on repeatable radiographic evaluation.
Overview of ASTM E446
ASTM E446, Standard Reference Radiographs for Steel Castings Up to 2 in. (50.8 mm) in Thickness, is used as a reference for interpreting radiographic images of steel castings within that thickness range. The standard supports more consistent evaluation by giving users a common point of comparison for discontinuity-related indications. In practice, it is commonly used alongside radiographic testing procedures to help align inspection results, improve communication between buyers and producers, and support more uniform quality decisions.
Common use cases of ASTM E446
This standard is commonly used during radiographic inspection of steel castings where thickness does not exceed 2 in. (50.8 mm). It is relevant in foundry quality control, receiving inspection, and contract review when cast components must be assessed against agreed acceptance criteria. ASTM E446 may also be used by inspectors, engineers, and purchasers who need a shared reference for comparing radiographs and documenting evaluation results in a consistent way.
Benefits of using ASTM E446
Using ASTM E446 can improve consistency in radiographic interpretation and reduce uncertainty during casting evaluation. It supports clearer communication between manufacturers, inspectors, and customers by providing an established comparison standard. That can help strengthen quality control, streamline acceptance decisions, and reduce the risk of disputes over radiographic findings. For organizations that purchase or produce steel castings, the standard can also support compliance-focused workflows and more dependable product assessment.
