Standard Specification for Metal Injection Molding (MIM) Ferrous Materials
ABSTRACT
This specification covers ferrous metal injection molded (MIM) materials fabricated by mixing elemental or pre-alloyed metal powders with binders, injecting into a mold, debinding, and sintering with or without subsequent heat treatment. These materials are: low-alloy steel produced from admixtures of iron powder and other alloying elements such as nickel and molybdenum (MIM-2200 and MIM-2700); low-alloy steel produced from admixtures of iron powder and other alloying elements such as nickel, molybdenum, and carbon (MIM-4605); austenitic stainless steel produced from pre-alloyed powder or an admixture of powders (MIM-316L); precipitation hardening stainless steel produced from pre-alloyed powder or an admixture of powders (MIM-17-4 PH); and ferritic stainless steel produced from pre-alloyed powder or an admixture of powders (MIM-430L). Chemical analysis shall be performed for the elements copper, chromium, molybdenum, and nickel. The materials shall be subjected to tensile test and unnotched Charpy impact energy test.
