Technical Specifications
Product Overview
Metallurgical Characteristics
SCM415 exhibits a tempered martensitic microstructure after proper heat treatment, providing an excellent combination of strength, toughness, and hardenability. The chromium content enhances hardenability and provides moderate corrosion resistance, while molybdenum additions improve high-temperature strength and reduce temper brittleness. The fine-grained structure achieved through controlled processing ensures uniform mechanical properties and excellent fatigue resistance.
Heat Treatment Process
MetalZenith employs a carefully controlled quenching and tempering process for SCM415. Austenitizing is performed at 850-880°C followed by oil quenching to achieve full martensitic transformation. Tempering at 550-650°C develops the optimal balance of strength and toughness. Our computer-controlled furnaces ensure precise temperature uniformity and cooling rates for consistent mechanical properties.
Manufacturing Excellence
Our production process begins with electric arc furnace melting using premium raw materials, followed by ladle refining and vacuum degassing to minimize inclusions. Continuous casting and controlled rolling optimize the grain structure, while our advanced heat treatment facilities ensure uniform properties throughout the material cross-section.
Structural Performance Testing
MetalZenith conducts comprehensive testing specific to structural applications including: welding performance evaluation per AWS D1.1 standards, forming capability assessment through bend testing, fatigue strength testing up to 10^7 cycles, and atmospheric corrosion resistance testing following ASTM G50 protocols. These specialized tests ensure SCM415 meets the demanding requirements of structural engineering applications.
Application Engineering Considerations
For building structures and bridge engineering, SCM415's high strength-to-weight ratio enables lighter designs while maintaining structural integrity. In machinery manufacturing, its excellent fatigue resistance and hardenability make it ideal for high-stress components. For vehicle manufacturing, the steel's formability and weldability facilitate complex geometries while providing crash resistance. In general engineering applications, SCM415's versatility allows for diverse heat treatment responses to meet specific performance requirements.
