Under minimum limit not applicable for elements where only a minimum percentage is indicated. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. This specification covers the requirements for wrought 18chromiumnickel However, long term clinical experience has shown an acceptable level of biological response can be expected, if the material is used in appropriate applications.

On the other hand, types of finish available for fine wire products are cold-drawn, ground, and ground and polished.

Approved June 10, This abstract is a brief summary of the referenced standard. Mm Ksi MPa Up to 0.

The chemistry modifications are designed to maximize the corrosion resistance of this alloy and provide a ferrite free microstructure.

Acceptance criteria shall be agreed to between pruchaser and supplier. The outcome equals considerably longer tool life, increased productivity, better chip breaking, better dimensional tolerances, superior machined surface quality, sstm scrap losses, and consistent performance which translates to a reliable production schedule.

C Cold-drawn wire may be ordered to tensile strengths up to psi MPa with lower elongation as determined by customer and supplier. A superscript epsilon e indicates an editorial change since the last revision or reapproval. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
