ANALYTICAL METHOD FOR THE DETERMINATION OF CARBON IN CARBON STEELS AND STAINLESS STEELS
Technical Report
·
OSTI ID:4105228
The steel in the form of swarf or turnings is ignited at 1350 deg C in an oxygen stream. The carbon dioxide evolved is isolated by meane of a cold trap cooled in liquid oxygen and measured after expansion at room temperature, as a gas volume. The method is applicable to carbon and stainless steels in the form of swarf, millings, turnings or powder. On British Chemical Standards, carbon steel stated to be 0.32% carbon, a value of 0.32%, with a standard deviation of plus or minus 0.0645% for a single meaeurement, was obtained on nineteen tests. On British Chemical Standards, 18/12 stainlees steel stated to be 830 ppm C, a value of 840 ppm, with a standard deviation of plus or minus 23 ppm for a single measurement, was obtained on 12 tests.
