What is ISO 23692 about?
ISO 23692 specifies procedures for quantitative analysis of Mn dendritic segregation in steel billets, blooms, slabs using electron probe microanalysis (EPMA).
The minimum size of analysable dendrites is dependent on the resolution of the microscope of EPMA, and the beam size of filament used for quantitative analysis.
Note 1: ISO 23692 is applicable to continuously cast products with Mn content of more than 0,01 % by mass.
Note 2: ISO 23692 used for steel ingots and steel products, such as cast iron and cast steel.
Who is ISO 23692 for?
ISO 23692 on quantitative analysis of Mn dendritic segregation is applicable to:
- Steel products or appliance manufacturers
- Ceramicists
- Metal alloys manufacturers
- Analyzers
Why should you use ISO 23692?
Electron probe X-ray microanalysis (EPMA) is a modern technique used to qualitatively determine and quantitatively measure the elemental composition of solid materials, including metal alloys, ceramics, glasses, minerals, polymers, powders, etc. on a spatial scale of approximately one micrometer laterally and in depth.
The dendritic segregation rich in Mn is unavoidable during steel solidification, which is the direct cause of banded structure in steel product formed in the hot rolling process. The toughness and strength of steel are greatly affected by the banded structure.
ISO 23692 provides method for quantification of the dendritic segregation can facilitate steel maker to optimize steel-making process parameters, and therefore control the banded structure in the final product.
