ISO 2938 Composition
The composition of ISO 2938 is of utmost importance as it determines its physical and mechanical properties. ISO 2938 is an alloy of carbon, manganese, sulfur, and phosphorus. The percentage of each component is critical and is usually controlled to ensure that the desired properties are achieved. The carbon percentage ranges from 0.28% to 0.34%, manganese from 0.60% to 0.90%, sulfur at 0.050%, and phosphorus at 0.050%. The sulfur and phosphorus percentages are controlled to reduce the effects of impurities, which negatively affect the mechanical properties of ISO 2938.
ISO 2938 Physical Properties
The physical properties of ISO 2938 are unique, making it distinguishable from other steels. ISO 2938 has a density of 7.85 g/cm3 and a melting point of 1420-1460 degrees Celsius. It has a thermal expansion coefficient of 11.7 x 10-6/K, which is critical in applications where changes in temperature due to expansion and contraction could cause structural damage. The electrical conductivity of ISO 2938 is 13% IACS, which makes it an ideal material for electrical applications.
ISO 2938 Mechanical Properties
The mechanical properties of ISO 2938 are impressive, making it an ideal steel material for different applications. The yield strength ranges from 315 to 490 N/mm2, while the ultimate tensile strength ranges from 490 to 660 N/mm2, depending on the heat treatment given to its structure. ISO 2938 also has a high fatigue limit, making it suitable for demanding mechanical applications. ISO 2938 can be machined easily, and its welding properties are excellent.
ISO 2938 Uses
ISO 2938 finds use in different industries for various applications. Its unique properties make it ideal for use in mesh wire, nails, bolts, nuts, threaded rods, welded wire mesh panels, rebars, and other construction materials. It is also used in the automotive industry for chassis components, suspension systems, and brake systems. ISO 2938 is also widely used in the electrical industry for wires, transformer cores, generators, and other electrical equipment where electrical conductivity and magnetic properties are essential.
ISO 2938 Hardness
ISO 2938 has a hardness range between 140 and 187 HB depending on the heat treatment applied. Heat treatment is critical in achieving the desired hardness for different applications. ISO 2938 can be hardened through various heat treatment methods, including annealing, normalizing, and tempering. The suitable heat treatment method depends on the desired application or use of ISO 2938.
ISO 2938 Heat Treatment
Heat treatment is crucial in achieving the desired properties of ISO 2938. Annealing is the process of heating the steel to a specific temperature and then cooling it slowly to make it more ductile and less brittle. Normalizing is heating the steel to a temperature above the critical range and then cooling it with air or oil. Tempering is heating the steel to a specific temperature and cooling it in perspective. The heat treatment process used for ISO 2938 depends on the desired properties and use of the material.
ISO 2938 is a unique carbon-manganese steel that has gained wide use in different industries due to its distinct chemical, physical, and mechanical properties. Its properties make it ideal for various construction, automotive, and electrical applications. ISO 2938 can be hardened through different heat treatment methods to achieve a desired hardness range for other applications. Understanding the composition, physical and mechanical properties used, hardness, and heat treatment of ISO 2938 is critical in choosing the suitable material for the desired application.
