In our offer you will find etching reagents for metallography, used to test metallographic defects. Furthermore, they are used in metallurgy for sample digestion, for microscopic and macroscopic investigations. In the same way testing the structure, welds and samples after hardening or carburizing is possible.
We offer reagents from Polish Standards or ASTM E407 standards. Reagents which you will not find in the table below we can offer especially for your order.
Metallography is a science about the construction of metals and their alloys.
Microscopic examinations – performed to tell the type, size, shape and distribution of structural components in the studied sample. They are carried out using metallographic microscope. The samples are buffed and polished and then etched thus revealing grains and grain borders accurately.
The most commonly used reagent for microscopic examination is Nital which reveals ferrite grains and the structure of alloys boundaries.
For iron alloys, specifically for cast iron it is common to use Pikral, which reveals grain boundaries and structural components.
Macroscopic examinations – consist in observation of samples with unaided eye or with a small magnification in order to rate the quality and to detect any flaws. You can detect, among others, cracks, blisters, pores, overfills, underfills, scratches, thicknesses of hardened or carburized layer, grain size and shape, fibrousness, lines of deformation.
We offer reagents for microscopic examination of iron alloys and additionally non-ferrous metals.
Adler’s reagent – used for macroscopic examination of welded joints. It reveals weld layers and heat affected zones specifically.
Baumann’s reagent – reveals the distribution of sulfur and phosphorus in the sample. Sulfur is a harmful admixture because it causes fragility when hot. The fact that silver sulphide formed in the reaction leaves black spots on the photographic paper is used for the study, which testify to sulfur concentrations. Phospores leave brighter spots similarly.
Anczyc’s reagent – shows places rich in phosphorus. Places with increased phosphorus content are darker.
Fry reagent – reveals the plastic deformation in carbonaceous steels containing nitrogen in addition to non-aging steels.
Jacewicz’s reagent – used for deep etching, reveals material discontinuities, non-metallic precipitation and fibrousness.
Furthermore, our top-selling metallography reagents are included in the table.
