Technical Specifications
Product Overview
Metallurgical Characteristics
HY-TUF exhibits a tempered martensitic microstructure with fine carbide precipitation, achieved through controlled quenching and tempering processes. The optimized alloy composition with chromium, molybdenum, and boron additions provides exceptional hardenability and strength while maintaining excellent toughness and weldability for structural applications.
Heat Treatment Process
MetalZenith employs controlled austenitizing at 900-930°C followed by water quenching and tempering at 620-680°C. This precise heat treatment cycle ensures optimal strength-toughness balance and stress relief, critical for structural integrity in load-bearing applications.
Manufacturing Excellence
Our advanced production process includes vacuum degassing, continuous casting, and controlled rolling to minimize inclusions and achieve uniform mechanical properties. Real-time monitoring systems ensure consistent quality and traceability throughout the manufacturing process.
Structural Performance Testing
HY-TUF undergoes comprehensive testing including weldability assessment per AWS D1.1 standards, bend testing for formability evaluation, fatigue testing up to 2 million cycles, and accelerated atmospheric corrosion testing. These tests ensure optimal performance in demanding structural environments.
Engineering Applications
For building construction, HY-TUF provides superior strength-to-weight ratios enabling lighter structural designs. In bridge engineering, its excellent fatigue resistance ensures long-term durability under cyclic loading. For machinery manufacturing, the combination of high strength and good machinability facilitates complex component fabrication. In vehicle construction, its crashworthiness and formability support advanced safety designs.
