UNS N06058 and ASTM B575 chemistry needs to be slightly changed to reflect recent modifications. The Mo, Cu, Al and P levels are now slightly different than orginally covered under UNS N06058. DIN has already approved these changes under 2.4700 while keeping the same designations to avoid confusion. It is suggested that the current UNS chemistry be changed as suggested and reflected in ASTM B575.
