Technical Specifications
Product Overview
Metallurgical Characteristics
DILLIDUR 400V features a fine-grained martensitic microstructure achieved through controlled quenching and tempering processes. The optimized chemical composition with controlled carbon content and strategic alloying elements ensures excellent hardenability while maintaining good weldability and formability. The microstructure provides superior wear resistance through high surface hardness combined with a tough core.
Heat Treatment Process
MetalZenith employs advanced heat treatment technology including controlled austenitizing at 900-950°C, followed by accelerated cooling to achieve the desired martensitic transformation. Subsequent tempering at 150-250°C optimizes the balance between hardness and toughness. Our computer-controlled furnaces ensure uniform temperature distribution and consistent mechanical properties throughout the plate thickness.
Manufacturing Process
The production process begins with electric arc furnace melting followed by ladle refining and continuous casting. Hot rolling is performed using advanced rolling mills with precise temperature control. The quenching and tempering line features rapid cooling systems and automated tempering furnaces to achieve optimal microstructure and mechanical properties. Final inspection includes ultrasonic testing and surface quality verification.
Quality Standards & Certifications
DILLIDUR 400V is manufactured in accordance with international standards including EN 10204-3.1, ASTM A514, and JIS G3128. MetalZenith maintains ISO 9001:2015, ISO 14001:2015, and OHSAS 18001 certifications. Each plate undergoes comprehensive testing including chemical analysis, mechanical property verification, dimensional inspection, and non-destructive testing to ensure compliance with specified requirements and customer expectations.
