1.1This specification covers high-silicon cast iron castings intended for corrosion-resistant service.
1.2This specification covers three grades as shown in Table 1. Selection of grade depends on the corrosive service to be experienced by the casting. All three grades are suited for application in severe corrosive environments. However, Grade 2 is particularly suited for application in strong chloride environments, and Grade 3 is recommended for impressed current anodes.
| Element | Composition, Weight % | ||
| Grade 1 | Grade 2 | Grade 3 | |
| Carbon | 0.65–1.10 | 0.75–1.15 | 0.70–1.10 |
| Manganese | 1.50, max | 1.50, max | 1.50, max |
| Silicon | 14.20–14.75 | 14.20–14.75 | 14.20–14.75 |
| Chromium | 0.50, max | 3.25–5.00 | 3.25–5.00 |
| Molybdenum | 0.50, max | 0.40–0.60 | 0.20, max |
| Copper | 0.50, max | 0.50, max | 0.50, max |
1.3The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.4The following safety hazards caveat pertains only to the test method portion, Section 9, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
