12、se in the manufacture of surgical implants. This part of ISO 5832 applies to materials in bar form up to a maximum diameter of 100 mm. NOTE The mechanical properties of a sample obtained from a finished product made of this alloy can differ from those specified in this part of ISO 5832. 2 Normative

Ingot analysis may be used for reporting all chemical
15、 requirements except hydrogen, which shall be determined after the last heat treatment and pickling procedure.

The grain size, determined as specified in Clause
17、6, shall be no coarser than grain size No. 4. at a magnification of 100 , and no alpha case or other foreign phases shall be visible. 5 Mechanical properties The tensile properties of the alloy, determined as specified in Clause 6, shall be in accordance with the requirements of Table 2. Should any
18、of the test pieces not meet specified requirements, two further test pieces representative of the same batch shall be tested in the same manner. The alloy shall be deemed to comply only if both additional test pieces meet the specified requirements. If a test piece fails outside the gauge limits, th
19、e test is invalid and a retest shall be performed. If any of the retests fails to meet the appropriate requirements, the product represented shall be deemed not to comply with this part of ISO 5832. However, the manufacturer may, if desired, subject the material to heat treatment again and resubmit
20、it for testing in accordance with this part of ISO 5832.
