We provide standard specimens of the microscopic structure of steel materials, along with detailed explanations through photographs.
This document introduces the "Microscopic Structure Standard Samples" handled by Yamamoto Scientific Tool Research Co., Ltd. Representative materials have been selected from the steel materials listed in JIS. These have been classified into categories from 1 to 7, and strict heat treatment has been applied to them, resulting in representative microscopic structures being produced at the Materials Technology Education Research Association. Additionally, the material properties, heat treatment conditions, and structures are thoroughly explained through actual standard samples, their photographs, and detailed descriptions to ensure a comprehensive understanding.

Yamamoto Scientific Tool Research Co., Ltd. is a specialized manufacturer of high-precision hardness reference specimens compliant with ISO and JIS standards. We handle high-precision hardness reference specimens, microscopic tissue standard specimens, spark test standard specimens, hard nesters, and Charpy impact reference specimens. Since ancient times, humanity has developed soft "iron" for tools and weapons, honing the technology to increase the carbon content in iron to enhance its strength, which has led to the use of various types of metals for a wide range of applications today. The high-precision hardness reference specimens compliant with ISO and JIS for indirect verification of hardness testers are widely used around the world, thanks to Japan's cultivation of hardness uniformity recognized globally and the standard values based on international standards.
