    Applicability and limitations

    The manufacturer's official website only lists nominal compositions: Cr 17.5%, Mo 28.5%, Si 3.4%; these single points are not permissible upper and lower limits and shall not be used for range reverse-lookup or standard guarantees.. C<0.08% is a strict upper limit.; Co is the base; Ni/Fe are listed as other elements but have no values.. N/O/P/S and Cr/Mo/Si ranges in the original reference library cannot be confirmed based on this table; original values are retained in the repair evidence. The manufacturer page lists both UNS/AMS as NotListed; do not invent identifiers..
