3 Chemical composition
The heat analysis shall conform to the requirements as to the chemical composition prescribed in Table 1. Ingot analysis can be used for reporting all chemical requirements except hydrogen, which shall be determined after the heat treatment and pickling procedure.
4 Microstructure
The microstructure, when examined as indicated in Table 3, shall be alpha + beta, and shall correspond to ISO 20160:2006, micrograph A 1 to micrograph A 9, for annealed material.
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 of the pieces not meet the specified requirements or should they break outside the gauge limits, 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 any of the retests fail to meet the appropriate requirements, the product represented shall be deemed not to comply with this part of Iso 5832.
6 Test methods
The test methods to be used in determining compliance with the requirements of this part of ISO 5832 shall be those given in Table 3.
Representative test pieces for the determination of mechanical properties shall be prepared in accordance with the provisions of ISO 6892-1.ISO 5832-11 pdf free download.
