Residual Element Analysis of American Standard Pressure Cast Steel
Steel is an important alloy material, which can be divided into several categories according to different industrial processes. Pressure casting is a common way to manufacture steel parts. Compared with other processes, pressure casting has the advantages of large shape and wide range of production. In order to meet the requirements of product safety, the residual element analysis of standard pressure cast steel should be strictly implemented.
The raw materials used in pressure casting should comply with relevant national standards. The chemical components to be checked mainly include carbon, silicon, manganese, sulfur, phosphorus, copper, chromium and other leading chemical components; and six other residual elements such as nickel, vanadium, titanium, molybdenum, cobalt, and aluminum should also be checked.
The casting of American standard pressure cast steel blocks should be tested for its physical properties. And after iquidation, the acid-soluble sulfur, silicon and other chemical components should also be tested by chemical method. Residual element analysis of pressure cast steel is mainly to analyze the content of six elements including nickel, vanadium, titanium, molybdenum, cobalt and aluminum. Can X ray fluorescence spectrometer be used for residual element analysis of American standard pressure cast steel.
Yes, X ray fluorescence spectrometer can be used for residual element analysis of American standard pressure cast steel. X ray fluorescence spectrometry is an effective method of chemical analysis, which is based on the principle of X ray fluorescence. Its main characteristics include wide application range, high detection limit and quick analysis speed. In addition, it is not afraid of interference by other elements and can be used to accurately measure residual elements in steel.
In addition, we also need to use energy dispersive X-ray spectrometry (EDX) to analyze the residual element content of American pressure cast steel, because EDX can collect higher resolution data on the trace element content than X ray fluorescence spectroscopy.
Measurement results should be evaluated and processed before they can be used for production. Generally speaking, only the qualified indicators of American standard pressure cast steel can be put into production. The allowable deviation range and process requirements for residual element analysis of American standard pressure cast steel are based on ASTM A743.
The allowable contents of nickel, vanadium, titanium, molybdenum, cobalt and aluminum in American standard pressure cast steel should meet the requirements of ASTM A743. The maximum limit of these elements ranges from 0.10% to 0.08%. In addition, their allowable deviations must be within the corresponding allowable ranges.
In summary, the residual element analysis of American standard pressure cast steel should be conducted strictly according to the relevant national standards. X ray fluorescence spectrometer and energy dispersive X ray spectrometer can be used for residual element analysis of American standard pressure cast steel. The qualified indicators must meet the requirements of ASTM A743. Otherwise, it is not allowed to put it into production.
