Technical Specifications
Product Overview
Metallurgical Characteristics
MS 1200 features a tempered martensitic microstructure optimized for ultra-high strength applications. The carefully balanced alloy composition promotes fine carbide precipitation during tempering, resulting in exceptional strength while maintaining adequate toughness. The low carbon content combined with strategic alloying minimizes weld cracking susceptibility while preserving hardenability.
Heat Treatment Process
MetalZenith's proprietary heat treatment involves austenitizing at 900-950°C followed by rapid quenching to achieve full martensitic transformation. Subsequent tempering at 580-620°C optimizes the strength-toughness balance. Our computer-controlled furnaces ensure uniform heating and precise temperature control throughout the process, with continuous monitoring of cooling rates and transformation kinetics.
Manufacturing Process Excellence
Production begins with vacuum induction melting of premium raw materials, followed by electroslag remelting for enhanced cleanliness. Hot rolling is performed using controlled thermomechanical processing to refine grain structure. MetalZenith's advanced rolling mills maintain precise temperature control and deformation schedules to optimize mechanical properties and dimensional accuracy.
Quality Standards & Testing
Every production lot undergoes comprehensive testing including chemical analysis by optical emission spectroscopy, mechanical property verification per ASTM standards, and ultrasonic testing for internal soundness. Charpy impact testing at various temperatures ensures adequate toughness, while fatigue testing validates long-term performance. MetalZenith maintains full traceability documentation and provides certified test reports with each shipment, ensuring compliance with aerospace AS9100D and automotive TS16949 quality management systems.
