Stainless steel precision casting manufacturers share how to determine the manganese content in precision castings:

Determination method of manganese content in precision castings

There has been no uniform rule for the determination of plutonium content in precision castings, and various methods are very different. For the promulgation of national standards and to meet the needs from time to time, we summarize and save here.

To measure the Mn of precision castings, you can find relevant national standards, such as GB/T 5121.14-2008. You can find the detailed answers you need, and there are very detailed steps.

Which brands of 721 measurement standards are determined, first refer to which national standards to see at which wavelength the actual measurement is measured, and then select 721 within 360-1000 to solve the problem. Otherwise, a spectrophotometer that looks like ultraviolet light is needed. If the budget is sufficient, you can choose Japan. If you have a small budget, you can choose domestic production.

In short, it is reported that the Mn content of the steel bid in the precision casting is given. After the steel is processed, a series of concentrations C are mixed with different solutions, and then the absorbance A is measured to form a standard curve. Then use the sample solution you prepared to measure the absorbance value, and get the Mn concentration according to the curve, then you can estimate the Mn content of the sample.
