鋼、ニッケル、コバルト合金における超低炭素・硫黄分析

Maintaining precise control over carbon and sulfur concentrations is vital in the production of steel, nickel-base, and cobalt-base alloys. Even trace amounts of these elements can significantly influence the mechanical properties of a material, affecting its ductility, weldability, and resistance to corrosion. Because surface contamination can cause substantial errors in analytical data, achieving reliable results at ultra-low levels requires both rigorous sample preparation and highly sensitive detection technology.

In this application, researchers utilize the CS444 carbon/sulfur determinator, which follows the ASTM E1019 combustion method. The process involves combusting a clean, representative sample in a high-frequency induction furnace within a pure oxygen environment.

By utilizing advanced infrared (IR) detection, the system accurately measures the carbon and sulfur gases released during combustion. This method, combined with the use of high-purity accelerators like LECOCEL II, ensures the rapid and precise determination of element levels, providing manufacturers with the data necessary to guarantee the quality and performance of high-strength industrial alloys.
