(Test Method)Standard Test Methods for Chemical Analysis of Chromium and Ferrochromium
Standard Test Methods for Chemical Analysis of Chromium and Ferrochromium
SIGNIFICANCE AND USE
These test methods for the chemical analysis of metals and alloys are primarily intended to test such materials for compliance with compositional specifications such as Specification A101 and A481. It is assumed that all who use these test methods will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that work will be performed in a properly equipped laboratory.
SCOPE
1.1 These test methods cover the chemical analysis of chromium and ferrochromium having chemical compositions within the following limits:
ElementConcentration, % Aluminum0.25 max Antimony0.005 max Arsenic0.005 max Bismuth0.005 max Boron0.005 max Carbon9.00 max Chromium 51.0 to 99.5 Cobalt0.10 max Columbium0.05 max Copper0.05 max Lead0.005 max Manganese0.75 max Molybdenum0.05 max Nickel0.50 max Nitrogen6.00 max Phosphorus0.03 max Silicon12.00 max Silver0.005 max Sulfur0.07 max Tantalum0.05 max Tin0.005 max Titanium0.50 max Vanadium0.50 max Zinc0.005 max Zirconium0.05 max
1.2 The analytical procedures appear in the following order:
Sections Arsenic by the Molybdenum Blue Photometric Test Method
[0.001 % to 0.005 %]10-20 Lead by the Dithizone Photometric Test Method
[0.001 % to 0.05 %]21-31 Chromium by the Sodium Peroxide Fusion-Titrimetric Test Method
[50 % to 75 %]32-38
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
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 whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 6.
10.1 This test method covers the determination of arsenic in chromium and ferrochromium in concentrations from 0.001 % to 0.005 %.
21.1 This test method covers the determination of lead in chromium and ferrochromium in concentrations from 0.001 % to 0.05 %.
32.1 This test method covers the determination of chromium in all carbon grades of ferrochromium in concentrations from 50 % to 75 %.
