Metroch is a solution for complete Micro graphic methods used
to test metal and their products. The wizard (modules) available are
confirming all equivalent national & international methods. The
available wizards are : GRAIN SIZE ASTM E-112, E-930, E-1181, ISO 643-03, JIS G 0551-05 BS 490 DIN 643-03, IS-4748-88, SIS 111101 GOST 5639-82.Determine feritic and austenitic Grain Size in Steel. Technique to analysisi: GRAPHITE FLAKES ASTM A247, ISO 9451-1, DIN EN 945-94, BIS 7754 JIS G5504, IS-7754. Flakes occuring in Cast Iron are designated by Form (by Roman no. I to VI) Distribution (designated by capital letter A to E) and Size (designated by Arabic no 1 to 8). Confirmity to Standards ASTM ISO 2639-02, BS-6479-84, IS-6416-88 JIS G0557 DIN 50790. The test determine the depth of hardened surface under low magnification by measuring the distance from the surface to the point shaving a different coloration towards core. COATING THICKNESS The test method covers measurement of the local thickness of metal and oxide coatings by microscopical examination of cross sections. DECARBURIZATION ASTM E1077, ISO 3887, JIS-0557-98 BS-6617-1, IS-7754 DIN 50192. The depth of decarburization in unalloyed and low alloy steel is determined by Micro graphic Method. Depth of Partial, total and complete decarburization is reported separately. NODULARITY ASTM A 247-67, ISO-9451-1, IS-7754 DIN E 945-94, JIS G5504, BIS 7754 JIS G5504. Nodules (spheroidal Graphite in Cast Iron) are separated from Non Nodules on predefined spheroidicity. Nodules/Sqmm are calculate and on the basis of its size and it is designed by Arabic no. 1 to 8 according to ASTM & ISO standards. POROSITY ASTM 247 Pores in casting are estimated and reported on the basis of intensity. The percentage is calculated. NON-METALLIC INCLUSION ASTM E-1245 E ASTM E45-97, ISO 4163-82, DIN 50602. The wizard determine contents of Non-metallic. Inclusion in rolled or forged steel products. According to ASTM, expression of results are in Group A, B, C, D along with segmentation of thick/thin and its severity level. |
