Wuxi Xiangxin Steel Co. ltd Provide the Inspection before shipping. Our company could provide the PMI ,  micrometer ,or Metal material analyzer to  test the quality, at the same time, Customer also could ask the third party for checking, such as SGS, BV,Sunshine ect.

Please check the chemical composition test method below.

1. Spectrometer
One is to use direct reading spectrometer to detect full elemental analysis, and can detect C element, and the other is X-ray fluorescence spectrometer. This method has fast detection speed, convenient instrument carrying, and accurate detection of components and grades.
2. metal material analyzer
The metal material analyzer is a metal material element analysis system that uses a high-frequency induction furnace with an infrared carbon-sulfur analysis system to quickly and accurately measure carbon steel, high-medium-low alloy steel, raw cast iron, gray cast iron, ductile iron, and alloy cast iron. Determination of elements in various materials such as ferroalloy, ferrosilicon, ferromanganese, ferronickel, ferrochrome, rare earth metals, coke, coal, slag, catalyst, ore. The instrument burns samples through a high-frequency induction furnace, and the content of C and S elements is determined by infrared analysis. Mn, P, Si, Cr, Ni, Mo, Cu, Ti, V, Al, W, Nb are determined by photoelectric colorimetry. The content of elements such as Mg and total rare earth.
