5.1 The chemical composition of high manganese steel alloys must be determined accurately to ensure the desired metallurgical properties. This procedure is suitable for manufacturing control and inspection testing.

1.1 This test method provides for the analysis of high manganese steel by spark atomic emission spectrometry for the following elements in the ranges shown:

Elements

Conposition Range, %

Aluminum (Al)

0.02 to 0.15

Carbon (C)

0.3 to 1.4

Chromium (Cr)

0.25 to 2.00

Manganese (Mn)

8.0 to 16.2

Molybdenum (Mo)

0.03 to 2.0

Nickel (Ni)

0.05 to 4.0

Phosphorus (P)

0.025 to 0.06

Silicon (Si)

0.25 to 1.5
