Alloy Guide Sheet Terms of Use

Use Good Design Principles

1. St. Paul Foundry is providing this information on metal characteristics for informational purposes only. Before making a final decision on alloy selection consider the following and all other appropriate design and specification principles. Please note that this is not an exhaustive list.

2. Consult the appropriate specification from an accredited specifying body (ASTM, SAE, Federal or Military) to determine current minimum values of this alloy.

3. Use appropriate design safety factors.

4. Use Failure Modes and Effects Analysis to help identify possible weaknesses in designs and specifications.

5. Use computerized stress analysis tools.

6. Use appropriate certification requirements for your casting suppliers. These may include test bars, chemical certifications, radiography, dye penetrant or other non-destructive testing methods.

7. Test your design to failure in a controlled environment. Then test it to failure in a simulation of its end use.

8. You and you alone are responsible for the suitability of your design and the materials that you select.
