ASTM-E327 › Test Method for Optical Emission Spectrometric Analysis of Stainless Type 18-8 Steels by the Point-To-Plane Technique (Withdrawn 1999)
Show Complete Document History
The following bibliographic material is provided to assist you with your purchasing decision:
1.1 This test method covers the optical emission spectrometric analysis of stainless Type 18-8 steels for the following elements:Element Concentration Range, % Chromium 17.0 to 20.0 Nickel 8.0 to 15.0 Manganese 0.8 to 2.0 Silicon 0.4 to 0.8 Copper 0.1 to 0.2
1.2 This test method is designed for routine analysis of chill-cast disks or inspection testing of stainless Type 18-8 steel flats upon which a surface of at least 13-mm (1/2-in.) diameter may be prepared. The samples must be sufficiently massive to prevent overheating during the discharge and of similar metallurgical condition and composition as the standards used.
1.3 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.
