SUS201 202 Stainless Steel Rectangular Pipe 0.3MM 1500MM weld multi-role
Environmentally friendly and recyclable
In addition to chromium, stainless steels are made with alloys of silicon, nickel, carbon, nitrogen, and manganese. Nitrogen, for example, improves tensile properties like ductility. Nickel is added to austenitic steel to improve flexibility. These alloys are added in varying amounts and combinations to meet specific end-use applications, which is why it’s very important for stainless steel manufacturers to verify that the correct percentages of each alloy are being used. There are two technologies that provide the elemental analysis needed to produce high quality stainless steel: X-Ray Fluorescence (XRF) and Optical Emission Spectroscopy (OES).
Handheld XRF is a highly valuable technology in the scrap metal market. Stainless steel is 100% recyclable and therefore a huge amount of stainless steel must be evaluated at the scrap yard. Handheld XRF analyzers bring immense value to scrap metal recyclers because it is a highly accurate, nondestructive testing technique that can analyze a metal sample in seconds with little to no need for sample preparation. With XRF, stainless steel scrap can be quickly analyzed and sorted according to grade and type.
OES is a robust, reliable, and widely-used technology for the analysis of metals and alloys in the lab. Compared with traditional combustion analyzers, OES provides faster elemental analysis with high precision and accuracy in iron and steel, aluminum, copper, magnesium, precious metals and other specialty metals/alloys. OES has demonstrated its capability to provide more efficient control of steel production by providing accurate sample analysis during the manufacturing process.
