Technical Specifications
Product Overview
Metallurgical Characteristics
EN36 exhibits a tempered martensitic microstructure with fine carbide precipitation, achieved through controlled austenitizing at 850-870°C followed by oil quenching and tempering at 550-650°C. The nickel-chromium-molybdenum alloying system provides excellent hardenability and toughness, while maintaining high strength levels essential for structural applications.
Heat Treatment Process
MetalZenith employs precise heat treatment cycles including stress relieving at 650°C, austenitizing in controlled atmosphere furnaces, and multi-stage tempering to achieve optimal mechanical properties. Our computer-controlled processes ensure uniform heating and cooling rates, critical for dimensional stability in structural components.
Manufacturing Excellence
Our EN36 production utilizes electric arc furnace melting with ladle refining, followed by continuous casting or ingot casting depending on final product requirements. Advanced hot working processes including controlled forging and rolling ensure optimal grain flow and mechanical property distribution throughout the material cross-section.
Structural Performance Testing
MetalZenith conducts comprehensive testing protocols including weldability assessment using standard procedures, forming performance evaluation through bend testing, fatigue strength determination via rotating beam testing, and atmospheric corrosion resistance testing in salt spray chambers. These specialized tests ensure optimal performance in structural engineering applications.
Application Engineering
For building construction, EN36 provides exceptional load-bearing capacity and seismic resistance. In bridge engineering, its fatigue resistance ensures long-term structural integrity under cyclic loading. Automotive applications benefit from its high strength-to-weight ratio, while heavy machinery applications utilize its excellent impact toughness and wear resistance in demanding operational environments.
