About This Item

 

Full Description

1.1 This test method provides for the X-ray spectrochemical analysis of stainless steels for the determination of the following elements in the ranges indicated:

ElementConcentration Range, %
Chromium11.0 to 19.0
Nickel0.20 to 13.0
Copper0.05 to 3.50
Molybdenum0.05 to 3.00
Manganese0.40 to 2.00
Columbium (Niobium)0.30 to 0.70
Cobalt0.05 to 0.50

Note 1--These concentration ranges can be extended by the use of suitable reference materials. The detection limit for the elements is lower than the listed value. The ranges represent the nominal levels at which this method was tested.

1.2 This test method is applicable to the control analysis of either chill-cast or wrought samples having a diameter of approximately 25 mm.

Note 2--Samples of greater or lesser size than those designated may be used with specially designed sample holders.

1.3 Matrix effects exist between the elements listed. To compensate for these effects, a series of calibration curves are required to cover the designated concentration ranges. The composition of the sample must approximate closely one or more of the reference materials used in the calibration curve which is applied. Mathematical corrections may also be used to solve for matrix effects. (Refer to Practice E1361.) A variety of such systems is commonly used. Any of these are acceptable that will achieve analytical accuracy equivalent to that reported for the method.

1.4 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. Specific hazard statements are given in Section 7.
