Technical Specifications
Product Overview
Metallurgical Characteristics
HY-100 exhibits a tempered martensitic microstructure achieved through controlled quenching and tempering processes. The low-alloy composition with nickel, chromium, and molybdenum additions provides exceptional hardenability and toughness. The fine-grained structure ensures uniform strength distribution and excellent impact resistance, making it ideal for high-stress structural applications requiring superior mechanical properties.
Heat Treatment Process
MetalZenith employs precision austenitizing at 870-900°C followed by controlled water quenching to achieve full martensitic transformation. Subsequent tempering at 580-620°C optimizes the strength-toughness balance while maintaining excellent structural integrity. Our advanced heat treatment facilities ensure uniform temperature distribution and controlled cooling rates for consistent mechanical properties.
Manufacturing Process Excellence
Our manufacturing process begins with electric arc furnace melting followed by ladle refining and vacuum degassing to achieve superior cleanliness. Continuous casting and controlled rolling optimize the microstructure before heat treatment. Advanced process control systems monitor temperature, time, and cooling rates throughout production to ensure consistent quality and performance.
Specialized Quality Testing
MetalZenith conducts comprehensive testing specific to structural applications including: welding performance evaluation using standard procedures, forming capability assessment through bend testing, fatigue strength determination under cyclic loading conditions, and atmospheric corrosion resistance testing in simulated environmental conditions. These specialized tests ensure optimal performance in demanding structural environments.
Structural Application Engineering
For building construction, HY-100's high strength-to-weight ratio enables lighter structural designs while maintaining safety factors. In bridge engineering, excellent fatigue resistance ensures long-term durability under dynamic loading. For machinery manufacturing, superior toughness prevents brittle failure in high-stress components. Vehicle manufacturing benefits from weight reduction without compromising structural integrity. General engineering applications leverage the combination of high strength, good weldability, and reliable performance across temperature ranges.
