Multi- element analyzer for stainless steel element detection and element classification

Stainless steel is a general name for stainless steel and acid-resistant steel. Stainless steel is a steel that is resistant to corrosion by weak media such as the atmosphere, steam, and water, while acid-resistant steel is a steel that is resistant to corrosion by acids, alkalis, salts, and other chemically etched media. QL-S3000C computer infrared all-round measurement of multi-element analyzer is the company's exclusive, domestic advanced multi-element tester , using computer to achieve program control and data processing. It can quickly and accurately measure the mass fraction of various elements in stainless steel, with a high degree of automation . The original element analyzer does not have a quantitative sample function, and it is accurate and reliable, and it is user-friendly.

There are many kinds of stainless steels and their properties are different. It has gradually formed several major categories in the course of development.

According to the organizational structure, it is divided into four categories : Markov stainless steel (including precipitation hardening stainless steel), ferritic stainless steel, austenitic stainless steel and austenite plus ferritic duplex stainless steel .

According to the main chemical composition of steel or some of the characteristic elements in steel, it can be divided into chromium stainless steel, chromium nickel stainless steel, chromium nickel-molybdenum stainless steel, low carbon stainless steel, high-molybdenum stainless steel, and high-purity stainless steel;

According to the performance characteristics of the steel and the use of classification, is divided into nitric acid-resistant stainless steel, sulfuric acid-resistant stainless steel, corrosion-resistant stainless steel, stainless steel, stress corrosion resistance, high-strength stainless steel, etc.;

Classified according to the functional characteristics of steel, divided into low-temperature stainless steel, non-magnetic stainless steel, free-cutting stainless steel, superplastic stainless steel.

At present, the commonly used classification methods are classified according to the characteristics of the steel structure and the chemical composition of steel and the combination of the two. Generally divided into martensitic stainless steel, ferritic stainless steel, austenitic stainless steel, duplex stainless steel and precipitation hardening stainless steel, or divided into two major categories of chromium stainless steel and nickel stainless steel.
