AMS 2175 Casting Visual Standards O'Fallon Casting

Although better known for delineating the frequency and inspection criteria for Radiography, Magnetic Particle and Penetrant Inspection, AMS 2175 also devotes substantial sections to quantifying the standards for Visual inspection. AMS 2175 requires a 100% Visual examination of every casting and provides some allowance for the existence of various types of small non

No. 123 Marking for Shipment (Civil Agencies) Cast Iron and Cast Steel Castings Quality Control, EX-work As for cast iron and cast steel parts, quality issues are always very important. The following will elaborate our experience to the quality control, ex-work inspection, material, visual, defects and dimensional examination. Also we will introduce standard inspection reports and certificates.

Due to the complexity of the process, defects can occur but we employ a comprehensive range of non-destructive testing and inspection techniques to provide quality assurance.

Feb 27, 2018 · MSS-SP-94 is a code on Quality Standard for Ferritic and Martensitic Steel Castings for Valves, Flanges, Fittings, and other Piping Components Ultrasonic Examination Method MSS-SP-147 is a code on Quality Standard for Steel Castings Used in Standard Class Steel Valves-Sampling Method for Evaluating Casting Quality Inspection Methods Overview and Comparisonsupplied. In the case of castings, separate test bars are cast at the same time as the part casting and from the same material used to pour the part casting. Although the tensile test is not normally conducted by the user of the metal product, it is important for the user to understand the test and its results.

Cleaning involves removal of sand, scale, and excess metal from the casting. Burned-on sand and scale are removed to improved the surface appearance of the casting. Excess metal, in the form of fins, wires, parting line fins, and gates, is removed. Inspection of the casting for defects and general quality is performed.

Non-Destructive Casting Quality Inspection Methods

There are many methods to test and detect issues inside the casting. These techniques help to make sure that it does not fail under load. The two main types of internal inspection methods are destructive as well as non-destructive testing. As the name implies, the destructive method involves opening up a casting, to check its metal properties SAE AMS2175 - Castings, Classification and Inspection of Class 4 - Castings not included in Class 1 or Class 2 and having a margin of safety greater than 200 percent. Grades. Castings, or sections of a casting, shall be of the following grades:Grade A - The highest quality grade of casting, or area of a casting, with minimum allowable discontinuities and very difficult to produce except in local areas.

STEEL CASTINGS HANDBOOK

To obtain the highest quality product, the part should be designed to take advantage of the flexibility of the casting process. The foundry must have either the part drawing or pattern equipment and know the number of parts to be made. To take advantage of the casting process, the foundry should also know which surfaces are to be machined STEEL CASTINGS HANDBOOKTo obtain the highest quality product, the part should be designed to take advantage of the flexibility of the casting process.

Standardization of Castings Quality

Digital radiographic imaging and recording/enhancement methods may be used if the casting supplier has documented proof that these methods result in a minimum equivalent sensitivity of 2 % and a 2-2T quality level. Wire-type image quality indicators are acceptable for use in accordance with ASTM E747. Visual Inspection of Castings Stainless Foundry Visual Inspection of Castings. Certain types of defects are obvious upon visual inspection of castings:cracked, tears, slag adhesions, blowholes, metal penetration, scabs, shifts, non-fill, cracked molds or cores and similar defects can be identified visually.
