Foreword

This revised standard adopts ASTMA518/A518M-99 (2008) "Corrosion resistant high silicon iron castings standards." This standard and ASTMA518/A518M-99 (2008) compared, there is a major difference in the technical content. --- Made larger editorial changes in the structure; --- Deleted ASTMA518/A518M-99 (2008), Chapter 6 analyzes the chemical composition, the use of chemical analysis method; --- Corresponding to our cast iron grades to replace the cast iron grades of ASTM; --- Removed appendix ASTMA518/A518M-99 (2008) of. This standard replaces GB/T 8491-1987 "Corrosion resistant high silicon iron castings." This standard compared with GB/T 8491-1987, the main technical changes as follows. --- Delete the original standard of four grades of materials and their respective chemical composition and mechanical properties; --- Adds three new grades of materials and their corresponding chemical composition and mechanical properties; --- Change the representation of material grades; --- Delete the original standard table 3 casting machining allowance; --- Delete the original table 4 standard casting defects allowed range; --- Increased bending test test rod specifications. Appendix A of this standard is an informative annex. The standard proposed by China Machinery Industry Federation. This standard by the National Foundry Standardization Technical Committee (SAC/TC54) centralized. This standard was drafted.
