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
