101.8 - Low Alloy Steels (disk and rod forms)

Steel and iron SRMs described here are furnished in various forms (disk, rod and chips) for optical emission and X-ray fluorescence spectrometric methods and for other methods of chemical analysis.

See also: Table 101.3 and Table 101.5.

Nominal Sizes for Solid Steel SRMs:
600 Series: 3.2 mm diameter and 51 mm long.
1100 and 1200 Series: 31 mm diameter and 19 mm thick.
1700 Series: 34mm diameter and 19 mm thick.
A "C" preceding the SRM number indicates a chill cast sample; 31 mm diameter and 19 mm thick.

PLEASE NOTE: The tables are presented to facilitate comparisons among a family of materials to help customers select the best SRM for their needs. For specific values and uncertainties, the certificate is the only official source.
