Specifies requirements for specific types of wear-resistant white iron.

This Standard specifies requirements for the following types of wear-resistant white cast iron: (a) White cast iron specified by hardness. (b) Nickel-chromium type. (c) High chromium type. NOTES:1 For advice and recommendations on information to be supplied by the purchaser at the time of enquiry and order, see AS 4738. 2 For information and advice on casting practices, see AS 4738.3 Information on heat treatment and microstructures of white cast irons is given in Appendix A. 4 Information on section size and chemical composition of nickel-chromium white cast irons is given in Appendix B.5 No provision has been made in this Standard for wear testing as wear rates depend on load, velocity, rate of loading, abrasive material, presence of fluids and many other factors which are difficult to reproduce. It is usually found that the testing of wear-resistant materials in their final application is more satisfactory than any smaller scale test. Anything other than a field test must be accepted as a compromise.
