Technical Specifications
Product Overview
Metallurgical Characteristics
Surgical Steel exhibits a fully austenitic microstructure with excellent grain boundary stability and resistance to sensitization. The controlled chromium-nickel-molybdenum composition provides superior corrosion resistance through passive film formation, while maintaining excellent mechanical properties for structural applications. The low carbon content prevents carbide precipitation, ensuring long-term structural integrity.
Heat Treatment Process
MetalZenith employs solution annealing at 1050-1100°C followed by rapid water quenching to achieve optimal austenitic structure. This process dissolves any carbides and ensures maximum corrosion resistance while maintaining excellent mechanical properties for structural applications.
Advanced Manufacturing Process
Our manufacturing process includes vacuum induction melting, electroslag remelting for enhanced cleanliness, and controlled rolling to achieve optimal grain structure. Advanced quality control includes ultrasonic testing, magnetic particle inspection, and comprehensive mechanical testing to ensure structural reliability.
Specialized Quality Testing
MetalZenith conducts extensive welding performance testing including HAZ toughness evaluation, forming capability assessment through bend testing, fatigue strength testing under cyclic loading conditions, and accelerated atmospheric corrosion testing in various environmental conditions to ensure superior performance in structural applications.
Structural Application Considerations
For building construction, Surgical Steel provides excellent resistance to environmental corrosion while maintaining structural integrity. In bridge engineering, its fatigue resistance and corrosion properties ensure long service life. For machinery manufacturing, the material offers precision machinability and dimensional stability. In vehicle construction, it provides lightweight strength with corrosion protection, while general engineering applications benefit from its versatility and reliability in diverse environmental conditions.
