Technical Specifications
Product Overview
Metallurgical Characteristics
RHA Steel features a tempered martensitic microstructure achieved through controlled quenching and tempering processes. The optimized alloy composition with chromium, nickel, and molybdenum additions provides exceptional strength-to-weight ratio and superior impact resistance. The fine-grained microstructure ensures uniform mechanical properties and excellent through-thickness performance critical for structural applications.
Heat Treatment Process
MetalZenith employs precision austenitizing at 870-900°C followed by controlled quenching in oil or polymer solutions to achieve optimal hardness. Subsequent tempering at 200-250°C ensures the desired strength-toughness balance while maintaining dimensional stability and stress relief throughout the material cross-section.
Manufacturing Excellence
Our advanced manufacturing process includes vacuum degassing, controlled rolling, and precise heat treatment cycles with continuous monitoring of temperature profiles and cooling rates. MetalZenith's state-of-the-art facilities ensure consistent quality and traceability throughout production, meeting the most stringent structural engineering requirements.
Specialized Quality Testing
RHA Steel undergoes comprehensive testing including welding performance evaluation using standard procedures, forming capability assessment through bend tests, fatigue strength analysis under cyclic loading, and atmospheric corrosion resistance testing in various environmental conditions. Additional ballistic testing and impact resistance verification ensure superior performance in demanding applications.
Application Engineering Considerations
For building structures and bridge engineering, RHA Steel provides exceptional load-bearing capacity and seismic resistance. In mechanical manufacturing, its high strength enables weight reduction while maintaining structural integrity. Vehicle manufacturing benefits from superior crash resistance and durability. General engineering applications leverage its excellent machinability and welding characteristics for complex fabrications requiring high-performance materials.
