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, %

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 %.
