Standard Specification for Metal Injection Molded (MIM) 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.
SCOPE
1.1 This specification covers ferrous metal injection molded 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.
1.2 This specification covers the following injection molded materials.
1.2.1 Compositions:
1.2.1.1 MIM-2200, low-alloy steel
1.2.1.2 MIM-2700, low-alloy steel
1.2.1.3 MIM-4605, low-alloy steel
1.2.1.4 MIM-4140, low-alloy steel
1.2.1.5 MIM-316L, austenitic stainless steel
1.2.1.6 MIM-17-4 PH, precipitation hardening stainless steel
1.2.1.7 MIM-420, martensitic stainless steel
1.2.1.8 MIM-430L, ferritic stainless steel
1.2.1.9 MIM-440, martensitic stainless steel
1.2.1.10 MIM-Cu, copper
1.3 Chemical composition limits are specified in Table 1.
1.4 With the exception of the values for density and the mass used to determine density, for which the use of the gram per cubic centimetre (g/cm3) and gram (g) units is the longstanding industry practice, the values in inch-pound units are to be regarded as standard. The values given in parentheses or in separate tables are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
