Yamamoto Scientific Tool Laboratory Spark test standard piece

In the spark test, the judgment of the component amount is rough compared to the precise analysis such as chemical analysis and spectroscopic analysis, but on the other hand, the judgment is not affected by the shape, roughness and heat treatment structure of the sample. 2. Non-destructive total number Inspection is possible (excluding finished products) 3. Equipment cost, time and labor are low. And so on.
1. Discovery of foreign material contamination 2. Decarburization, confirmation of presence of carburized layer 3. Discrimination of contained elements, estimation of content 4. Estimation of steel type 5. Estimation of component amount before precise analysis (100% inspection is possible) Others , High temperature oxidation resistance, nitriding, determination of whether or not it is hardened, etc.
