Explore the application of handheld analyzers in the stainless steel industry

Stainless steel refers to steel that is resistant to corrosion by weak corrosive media such as air, steam and water, as well as chemical corrosive media such as acids, alkalis and salts. It is also known as stainless acid-resistant steel. The content of different alloy components in stainless steel has a significant impact on the corrosion resistance, high-temperature oxidation resistance and mechanical strength of stainless steel. The basic alloying elements of stainless steel include Fe, Cr, Ni, Mn, Mo, N, Cu, Nb, Ti, Si and other elements. Different proportions and compositions are used to meet the requirements for the microstructure and properties of stainless steel for different applications.

The following takes the commonly used stainless steels 304 and 316 in our production and life as examples to introduce the application of handheld alloy analyzers in the rapid detection of stainless steel grades.

304 stainless steel, also known as 18/8 stainless steel, has the GB grade of 06Cr19Ni10. 316 stainless steel is also a widely used steel grade, with the GB grade of 022Cr17Ni12Mo2. It is mainly used in the food industry and surgical instruments. The addition of molybdenum gives it a special structure that is resistant to corrosion. 316 contains a higher content of nickel and molybdenum alloys, which makes its price higher than that of 304. In actual trade, it is difficult to quickly distinguish different types of steel grades, which may cause significant losses to users and also bring certain product quality and even safety hazards.

In actual production and life, due to the difficulty in distinguishing 316 and 304 stainless steel in appearance and the fact that conventional analysis methods are rather cumbersome and time-consuming, the handheld alloy analyzer is a portable spectrometer specifically designed for on-site use. It can quickly, non-destructively and accurately provide information on the composition, content and grade of stainless steel materials. It is very suitable for on-site screening and re-inspection of a large number of raw materials and products.

The KMX-RAY K-8000 alloy analyzer can non-destructively, rapidly and accurately analyze and detect alloy elements and identify alloy grades on-site. Rapidly analyze the content of more than 29 elements ranging from titanium (Ti) to uranium (U).
