This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

3.Ordering Information
3.1The material furnished under this specification shall be crushed to the specified size, and mixed before packaging, so that the
quality in each package is uniform with the lot.
3.2The reported percentage of titanium as obtained by chemical analysis shall be used to determine the billing of the material
to the purchaser.
4.Chemical Composition
4.1The various grades shall conform to the requirements as to chemical composition prescribed in Tables
1-A 1025 Specification for Ferroalloys and Other Alloying Materials, General Requirements
3. General Conditions for Delivery
3.1 Materials furnished to this specification shall conform to the requirements of Specification A 1025, including any
supplementary requirements that are indicated in the purchase order. Failure to comply with the general requirements of
Specification A 1025 constitutes nonconformance with this specification. In case of conflict between the requirements of this

5. Size
5.1 The various grades are available in sizes as listed in Table 3.
5.2 The sizes listed in Table 3 are typical as shipped from the manufacturer’s plant. These alloys exhibit varying degrees of
friability; therefore, some attrition may be expected in transit, storage, and handling.Aquantitative test is not available for rating
relative friability of ferroalloys. A code system has been developed, for this purpose, and a number rating each product type is
shown in the last column of Table 44. Definitions applicable to these code numbers are given in Specification A 1025.
5.Chemical Analysis
5.1The chemical analysis of the material shall be made in accordance with a procedure agreed upon between the manufacturer
and the purchaser.
6.Sampling
6.1The material shall be sampled in accordance with Practices E32.
