Technical Specifications
Product Overview
Metallurgical Characteristics
EN 1.4541 is an austenitic stainless steel stabilized with titanium to prevent intergranular corrosion in the temperature range of 425-815°C. The titanium content forms stable carbides (TiC) that prevent chromium carbide precipitation at grain boundaries, maintaining corrosion resistance even after welding or high-temperature exposure. The austenitic microstructure provides excellent ductility and toughness across a wide temperature range.
Heat Treatment Process
MetalZenith employs controlled atmosphere solution annealing at 1050-1100°C followed by rapid cooling to achieve optimal properties. Our advanced heat treatment facilities feature precise temperature control (±5°C) and protective atmosphere systems to prevent oxidation and decarburization. Post-annealing stress relief at 850-900°C may be applied for specific applications requiring dimensional stability.
Manufacturing Process Excellence
Our integrated production process begins with electric arc furnace melting followed by AOD refining for precise composition control. Continuous casting ensures homogeneous structure, while our multi-stand hot rolling mills with computerized process control deliver consistent mechanical properties. Cold working capabilities include precision rolling, drawing, and forming operations with intermediate annealing cycles to maintain optimal microstructure.
Quality Standards & Testing
All EN 1.4541 products undergo comprehensive testing including optical emission spectroscopy for chemical analysis, tensile testing per ASTM A370, intergranular corrosion testing per ASTM A262 Practice A, and ultrasonic inspection for internal soundness. Our quality management system ensures compliance with EN 10204 3.1 certification requirements, providing complete material traceability from raw materials to finished products. Advanced metallographic examination verifies grain size, inclusion content, and phase distribution according to ASTM E112 and E45 standards.
