Foreword
This standard is in accordance with GB/T 1.1-2009 given rules drafted.
This standard replaces GB/T 17792-1999 "molybdenum and molybdenum alloy bar."
This standard compared with GB/T 17792-1999, the main changes are as follows.
--- Increased Mo2, MoLa alloy bar products and their requirements;
--- Revised sintered and extruded bar of predetermined diameter range and size deviation;
--- Revised sintered density requirements for bar products;
--- The content of chemical composition, test methods, inspection rules were revised;
--- Increasing the product contracts (or orders) content.
This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized.
