Organization: ASTM
Publication Date: 1 April 2015
Status: active
Page Count: 4
ICS Code (Powder metallurgy): 77.160
scope:

This specification covers parts produced from ironphosphorus powder metallurgy materials. These parts are used in magnetic applications requiring higher permeability and electrical resistivity and lower coercive field strength than attainable routinely from parts produced from iron powder.

Two powder types are covered; Type I containing nominally 0.45 wt.% phosphorus, and Type II containing nominally 0.8 wt.% phosphorus.

This specification deals with powder metallurgy parts in the sintered or annealed condition. Should the sintered parts be subjected to any secondary operation that causes mechanical strain, such as machining or sizing, they should be resintered or annealed.

The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to customary (cgs-emu and inch-pound) units, which are provided for information only and are not considered standard.

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 and health practices and determine the applicability of regulatory limitations prior to use.
