ASTM E – 08 Standard Practice for Preparing Sulfur Prints for Macrostructural Evaluation

Selection of appropriate printing practices including selection of type of emulsion coated media, acid type and strength, will yield satisfactory prints. The layer of magnetite on the surface of A is thicker than that of A P22, due to the different amount of chrome content.

The magnetite is formed by controlling the water chemistry and e1810 temperature of fluid inside the facility. The experimental facility allows examining liquid droplet impingement erosion in the same conditions as the secondary side piping in nuclear power plants by generating the magnetite on the surface of the test materials.

However, the materials of pipes carrying two-phase flow should be selected considering their susceptibility to LDIE. In the initial stage of the experiments, the mass astn rate of A B was greater than that of A P In nuclear power plants, carbon steel piping having experienced wall thinning degradation is generally replaced with low-alloy steel piping.

An experimental facility was set up to develop a prediction model for clarifying multiple degradation mechanisms that occur together.

Scientific Research An Academic E11800. It is presumed that the results are caused by the different yield strengths of the test materials and the different degrees of buffer action of the magnetite deposited on their surfaces. Steels with compositions that produce predominantly titanium or chromium sulfides will not produce useful images.

Historical Version s – view previous versions of standard. For specific precautionary statements, see Section 9. Link to Active This d1180 will always route to the current Active version of the standard.

It is the responsibility of the user of this standard to asstm appropriate safety and health practices and zstm the applicability of regulatory limitations prior to use. Very faint images in the sulfur print can be made more visible by scanning the sulfur print into a PC, and using a photo editor to increase the color saturation.

Very low sulfur content steels will produce too faint an image to be useful for macrostructural evaluations. It has been thought that wall thinning on the secondary side piping in nu-clear power plants is mostly caused by Flow-Accelerated Corrosion FAC.

No other units of measurement are included in this standard. Under carefully controlled conditions, aetm is possible to compare print image intensities if the images are formed only by manganese sulfides.

The density of the print image should not be used to assess the sulfur content of a steel. However, after a certain period aztm time, the mass loss rate of A P22 became greater than that of A B.

The sulfur print complements macroetch methods by providing an additional procedure for evaluating the homogeneity of a steel product. This paper presents a comparison of the mass loss rate of the tested materials between carbon steel A B and low alloy steel A P22 resulting from degradation effect.
