MPIF - 35 P/F STEEL PARTS
Materials Standards for P/F Steel Parts
|Publication Date:||1 January 2000|
MPIF Standard 35 is issued to provide the design and materials engineer with the information necessary for specifying powder metal (P/M) material which have been developed by the P/M parts manufacturing industry. This section of Standard 35 deals with products manufactured by powder forging (P/F). It does not apply to conventional P/M structural materials, self-lubricating bearings or metal injection molded materials which are covered in subsequent sections. Each section is divided into subsections based on the various types of P/F materials in common commercial use within that section. Notes at the beginning of each subsection discuss the characteristics of that material.
The use of any MPIF Standard is entirely voluntary. MPIF Standards are issued and adopted in the public interest. They are designed to eliminate misunderstandings between the manufacturer and the purchaser and to assist the purchaser in selecting and obtaining the proper material for his particular product. Existence of MPIF Standard does not in any respect preclude any member or non-member of the Federation from manufacturing or selling products which use materials or testing procedures not included in this Standard. Other materials which are not covered in this Standard may be commercially available.
By publication of these Standards, no position is taken with respect to the validity of any patent rights nor does the Metal Powder Industries Federation undertake to ensure anyone utilizing the Standards against liability for infringement of any Letters Patent or accept any such liability.

MPIF Standards are subject to periodic review and may be revised. Users are cautioned to refer to the latest edition.
Both the purchaser and manufacturer should, in order to avoid possible misconceptions or misunderstandings, agree on the following conditions prior to the manufacture of a P/F component: material selection, chemistry, proof testing, typical property values and processes, which may affect the part application.
