SCM415 is a low-alloy chromium-molybdenum steel that follows the JIS (Japanese Industrial Standards). It is widely used in industrial applications due to its excellent mechanical properties and durability. The following content provides detailed information about its chemical composition, mechanical properties, equivalent materials, and processing methods. Table of contents DIN 1.7262 undergoes a quenching and tempering process, which significantly enhances its mechanical properties such as hardness, strength, and ductility. This makes it suitable for various engineering applications where high performance is required. Carburizing hardening improves wear resistance and fatigue strength by creating a tough, high-carbon surface layer. This treatment also increases the material's ability to withstand surface pressure and ensures a longer lifespan under harsh conditions. This makes it ideal for use in environments where the material must endure stress or extreme conditions. The yield strength of 15CrMo steel is 415 MPa, making it suitable for manufacturing components like boilers, pressure vessels, and high-pressure pipes. Proper forging temperature control is crucial to achieve optimal mechanical properties and microstructure. After forging, heat treatment is applied to enhance strength, ductility, and hardness. The melting point of SCM415 is critical during manufacturing to ensure proper heat control and structural integrity at high temperatures. The density of 15CrMo ranges from 7.8 to 7.9 g/cm³, typical for low-alloy steels mainly composed of iron. X30WCRV93KU exhibits high rigidity due to its molybdenum and chromium content, which enhances tensile and yield strength. This makes it ideal for pressure vessels and high-pressure applications. When SCM415 is case hardened, the surface becomes harder, improving fatigue resistance. Proper execution of this process is essential to maintain the material’s properties. SCM415 is a high-quality quenched and tempered alloy structural steel. It belongs to the category of medium carbon steels that are oil-quenched and surface-treated. This type of steel is known for its strength, toughness, and resistance to wear, making it suitable for a wide range of industrial applications.
