ASTM A705 Grade 630 condition H1075
A number in parentheses indicates the year of last reapproval. 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. Current edition approved May 1, Originally approved in Such requirements may include but are not limited to the following: NOTE 2—A typical ordering description is as follows: Failure to comply with the general requirements of Speci?
Materials and Manufacture 5. The cuts shall be made to the required length by a qstm process. This material may be speci? C Columbium plus tantalum 0. F Columbium plus tantalum 0. G Columbium 8 times carbon minimum.

Either Rockwell C hardness or Brinell is permissible. On sizes of 1? C BHN for rounds cold drawn after solution treating. The limiting asfm offset shall be 0. Prolongations for Tests 8. The producer may elect to submit an extra forging to represent each test lot instead of prolongations, or the test specimens can be taken from the forgings themselves.
Number of Tests 9. Quench air cool Brinell, min H H  4. Warm in air to room temperature.
RH Up to 4 in. Hold for not less than 3 h. H 0. H  4. Time refers to minimum time material is at temperature and may asmt extended to obtain required ductility properties. C Unless otherwise noted, temperatures shown s705 suggested temperatures and may be varied to obtain required tensile properties. D Intermediate temperatures must meet the ductility requirements of the next highest suggested hardening or aging temperature, or both.
E L – Longitudinal axis of specimen parallel to direction of grain? T – Transverse axis of specimen perpendicular to direction of grain?
G Either Rockwell C hardness or Brinell is permissible. Applies to consumable electrode vacuum remelted. Only tensile strength applicable to sizes up to 1? K Consumable electrode remelted only.
