Technical Specifications
Product Overview
Metallurgical Characteristics
QT 100 features a tempered martensitic microstructure achieved through controlled quenching and tempering processes. The optimized alloy composition with chromium, molybdenum, and nickel additions provides enhanced hardenability and improved mechanical properties. The fine-grained microstructure ensures excellent strength-toughness balance critical for structural applications.
Heat Treatment Process
MetalZenith employs austenitizing at 880-920°C followed by water or oil quenching to achieve martensitic transformation. Subsequent tempering at 580-650°C optimizes the strength-toughness relationship while maintaining excellent weldability. Our controlled atmosphere furnaces ensure uniform heating and precise temperature control throughout the process.
Manufacturing Process Excellence
Our advanced manufacturing process includes electric arc furnace melting with secondary refining, continuous casting, and controlled rolling. MetalZenith's integrated production line ensures consistent chemical composition and mechanical properties while minimizing inclusions and segregation for superior structural performance.
Specialized Quality Testing
QT 100 undergoes comprehensive testing including weldability assessment per AWS D1.1, formability evaluation through bend testing, fatigue strength analysis using rotating beam testing, and atmospheric corrosion resistance evaluation. Our quality control program ensures compliance with structural engineering requirements and long-term durability.
Structural Application Engineering
For building construction, QT 100 provides exceptional load-bearing capacity with reduced weight. In bridge engineering, its high fatigue resistance ensures long service life under cyclic loading. For machinery manufacturing, the steel offers superior wear resistance and dimensional stability. Vehicle applications benefit from enhanced crash performance and structural integrity, while general engineering applications leverage its versatile processing characteristics and reliable performance.
