Quantitative Analysis of Low Alloy Steel using the Supermini200

This application note describes low alloy steel analysis using the Supermini200, which is optimized for process control.

Background

Alloy steels with up to 4 or 8% of alloying elements added are called low alloy steels. Low alloy steels are made by adding various elements intended to improve a specific characteristic of steel such as hardenability. Alloy steels are generally made in electric furnaces. The concentration of elements in molten steel are adjusted during the process of steel making, so that rapid analysis of the elemental composition is required. As part of the control of the steel making process, analyses of slag and raw materials such as quicklime and ferroalloys are also required. X-ray fluorescence spectrometers are the most common analysis tools to analyze steel owing to rapid analysis and the ability to measure both bulk metal and powders.

The new Supermini200 has improved software capabilities as well as a better footprint. As the world's only high-power benchtop sequential wavelength dispersive X-ray fluorescence (WDXRF) spectrometer for elemental analysis of oxygen (O) through uranium (U) of almost any material, the Rigaku Supermini200 uniquely delivers low cost-of-ownership (COA) with high resolution and lower limits-of-detection (LLD).
