The Japanese Easily Cut Steel Number
Steel is a material that has been used for centuries and is still widely used in a variety of industrial, construction and engineering applications. Many of these applications rely on being able to accurately determine the strength and quality of a specific steel, and consequently steel is typically categorised and marked to indicate the type and grade of the steel in question. In Japan, the steel grade is usually indicated using the Japanese Easily Cut Steel Number.
The basic categorisation system is based on three key factors. These are the tensile strength, the chemical composition and the mechanical properties. The strength of the steel is indicated by the numerical code that forms the first part of the designation. This typically ranges from 01 to 26, where usually higher numbers reflect higher tensile steel strength. The chemical composition is then specified as a sequence of numbers which vary depending on the specific type of steel.
The mechanical properties are determined by three other numbers. The first number indicates the interior structure, the second the martensitic structure and the third the melting point. It should be noted that whereas the numerical codes may reference a specific type of steel, the actual steel used may not have all of the same properties as the coded number suggests. As such manufacturers must still ensure that they are well informed on the exact type of quality of steel they are purchasing or manufacturing with.
The Japanese Easily Cut Steel Number is particularly useful for industrial and engineering related applications, as it allows for quick recognition of the kind of steel that is being used. This system is also useful for anyone who is looking to purchase or sell a particular kind of steel, as it allows for quick identification and specification of the type of steel in question. This has resulted in the category becoming the international standard for steel designation and used across the world.
Overall, the Japanese Easily Cut Steel Number has proven to be an efficient and effective way for categorising different types of steel and ensuring that a known level of quality is maintained. The code is widely accepted throughout the engineering and steel industries, and by using the code, companies of all sizes are able to ensure they are purchasing and manufacturing the best quality steel possible.
