TI–PD GRADE 7 & GRADE 16Ti-0.15Pd (Grade 7)This alloy has mechanical properties similar to Commercially Pure Titanium Grade 2 but has improved resistance to general and localised crevice corrosion in a wide range °F reducing acid environments including chlorides, with a good balance °F moderate strength, reasonable ductility and excellent weldability.Ti-0.05Pd (Grade 16)Grade 16 is identical to Grade 7 with the exception that the palladium added to improve corrosion resistance is less than with Grade 7. Mechanical and physical properties, specifications and forms are all identical to those °F Grade 7.The alloy composition differs by the reduction °F Pd to 0.04-0.08%.Note: The poor availability and high cost °F palladium have led to the development °F ruthenium as an alternative alloy addition to provide similar enhancement °F corrosion resistance but at lower cost. The relevant ASTM Grades is 26 (CP Grade 2 + 0.1% Ru). Mechanical and physical properties are °F the same order as described for grades 7 and 16.CompositionC Fe N2 Pd 0.12-0,.25 % for Grade 7 and 0.04-0.08% for Grade 16O2 H2(sheet) H2(bar) Ti ~ RemSpecifications/Designations for Grades 11 and 17ASTM B265ASTM B337 Gr7 onlyASTM B338ASTM B348ASTM B363 (WPT)ASTM B381ASTM B861ASTM B862ASTM B863ASTM F467 Gr7 FastenersASTM F468 " "See also ASTM list °F B367 casting grades °F palladium containing alloys for approximate equivalent specifications to the wrought grades above. Physical Data                                                        TypicalDensity g/cm3 (lb/cu.in)                                4.51 (0.162)Melting Range°C±15°C (°F)                           1677 (3051)Specific Heat J/Kg/°C (BTU/lb/°F)                     540 (.129)Volume Electrical Resistivity mohm.cm(mohm.in)          56 (22)Thermal Conductivity W/mk (BTU/ft h°F)                 20.6 (143)Mean Thermal Exp.
