1 Introduction
JIS G2316-1986, known as the Japanese Nickel-Iron, is the national standard of Japan issued by the Japan Industrial Standard (JIS). It is the most important material standard in Japan and is widely applied in the production, inspection and acceptance of various iron, alloy and non-ferrous metal products.
2 History
The JIS G2316-1986 standard dates back to the late 1950s when Japanese manufacturers began to mass produce iron and steel products for domestic consumption as well as for export. The Japanese Nickel-Iron standard was established to ensure high quality and uniformity of materials used in different industries. Today, it is the single most applicable standard in Japan and is used in the production, acceptance and inspection for a variety of steel, nickel and non-ferrous metal products.
3 Scope
JIS G2316-1986 governs the manufacture, inspection, and acceptance of nickel and iron products. These products include alloyed and non-alloyed steel, as well as an array of non-ferrous metals. The standard provides guidelines on the chemical composition and mechanical properties of such materials. It also details the testing methods and inspects to be followed when inspecting the products during and after their manufacture.
4 Physical Specifications
The JIS G2316-1986 standard sets out the physical characteristics that must be met by the material in order to be compliant. Depending on the material, physical properties such as tensile strength, ductility, hardness, and grain or stress orientation may be specified. These properties provide essential information about the material’s strength, durability and ability to withstand various environmental conditions.
5 Test Methods
The JIS G2316-1986 standard specifies a number of tests to be applied to ensure the quality of the material. These tests include ultrasonic testing, chemical analysis, mechanical testing and metallographic examination. Such tests are used to assess the material’s mechanical, chemical and physical properties in order to guarantee that the material is of an acceptable quality.
6 Corrosion Resistance
The JIS G2316-1986 standard also outlines the corrosion resistance characteristics for a material. Corrosion resistance is the material’s ability to withstand corrosion when exposed to a corrosive environment. This is of particular importance when selecting materials for outdoor applications. The standard outlines the requirements for the corrosion resistance of a material, as well as the methods used to assess its performance.
7 Conclusion
The JIS G2316-1986 is the most important standard in Japan and is adopted by most manufacturers when producing, inspecting, and accepting iron and steel products. It outlines the physical, mechanical and chemical properties that are required for the production of quality materials, as well as the testing methods and acceptance criteria. The standard is an essential reference for any company looking to acquire high-quality materials produced in Japan.
