Technical Specifications
Product Overview
Metallurgical Characteristics
Sleipner steel features a complex carbide structure with primary chromium carbides and secondary vanadium carbides distributed in a martensitic matrix. The high chromium content provides excellent wear resistance and dimensional stability, while molybdenum enhances hardenability and toughness. The refined microstructure achieved through controlled processing ensures superior mechanical properties for structural applications.
Heat Treatment Process
MetalZenith employs controlled austenitizing at 1020-1050°C followed by air cooling or oil quenching, then tempering at 150-200°C for optimal hardness retention. For structural applications requiring enhanced toughness, modified tempering cycles at 400-500°C can be applied to achieve the desired balance of strength and ductility.
Manufacturing Process Excellence
Our advanced manufacturing process includes vacuum induction melting for chemical homogeneity, controlled forging for grain refinement, and precision heat treatment with computerized temperature control. Quality assurance includes ultrasonic testing, hardness mapping, and microstructural analysis to ensure consistent properties throughout the material.
Specialized Quality Testing
Comprehensive testing protocols include welding performance evaluation using standard procedures, forming characteristic assessment through bend testing, fatigue strength determination via rotating beam tests, and atmospheric corrosion resistance testing in controlled environments. These specialized tests ensure optimal performance in structural applications.
Structural Application Considerations
For building frameworks and bridge construction, Sleipner steel provides exceptional load-bearing capacity and long-term dimensional stability. In machinery manufacturing, its wear resistance and precision machinability enable tight tolerances. For automotive applications, the combination of high strength and fatigue resistance ensures reliable performance under dynamic loading conditions.
