This standard specifies the requirements for forged/rolled CTC segments. The segments must be made from either nonmagnetic austenite stainless steel or magnetic martensite stainless steel. The chemical compositions must meet any of the grades specified in the standard. The mechanical properties of the steels must meet the requirements specified in the standard. The segments must be machined in the sequence as defined in the standard.


Test shall be carried out in accordance with the method prescribed.

  • Tensile test
