Technical Specifications
Product Overview
Metallurgical Characteristics
EN 1.4016 is a ferritic stainless steel with a body-centered cubic (BCC) crystal structure. The chromium content of 16-18% forms a protective passive oxide layer, providing excellent corrosion resistance in atmospheric and mildly corrosive environments. The ferritic structure makes this grade magnetic and non-hardenable by heat treatment, offering good formability and weldability characteristics.
Heat Treatment Process
MetalZenith employs controlled annealing processes at 750-850°C followed by air cooling or controlled cooling to achieve optimal grain structure and mechanical properties. Solution annealing at 850-950°C may be applied for stress relief and maximum corrosion resistance. Our advanced furnace technology ensures uniform heating and precise temperature control throughout the material cross-section.
Manufacturing Process
Our production process begins with electric arc furnace melting followed by AOD refining for precise chemistry control. Continuous casting produces high-quality billets, which undergo hot rolling, cold rolling, and annealing cycles. MetalZenith's advanced rolling mills achieve excellent surface quality and dimensional accuracy. Final processing includes pickling, passivation, and surface finishing according to customer specifications.
Quality Standards & Testing
Every batch undergoes comprehensive testing including chemical analysis by optical emission spectroscopy, mechanical testing per ASTM standards, intergranular corrosion testing (ASTM A262), and dimensional inspection. MetalZenith maintains full traceability from raw materials to finished products, ensuring compliance with international quality standards and customer specifications.
Corrosion Resistance & Performance
EN 1.4016 exhibits excellent resistance to atmospheric corrosion, water, and mild chemical environments. The material demonstrates superior performance in automotive exhaust applications, kitchen equipment, and architectural applications. MetalZenith's optimized chemistry and processing ensure maximum corrosion resistance while maintaining excellent formability for complex forming operations.
