Technical Specifications
Product Overview
Metallurgical Characteristics
M50 steel features a martensitic microstructure with uniformly distributed primary and secondary carbides. The high chromium and molybdenum content provides excellent hardenability and wear resistance, while vanadium additions contribute to fine carbide formation and enhanced toughness. This combination makes it exceptionally suitable for high-stress structural applications.
Heat Treatment Process
MetalZenith employs controlled austenitizing at 1010-1040°C followed by oil or air quenching and double tempering at 540-560°C. This process optimizes the balance between hardness and toughness while ensuring dimensional stability critical for structural applications.
Manufacturing Excellence
Our advanced manufacturing process includes vacuum melting for superior cleanliness, controlled forging for optimal grain flow, and precision heat treatment using computer-controlled furnaces. Quality control includes ultrasonic testing, magnetic particle inspection, and comprehensive mechanical property verification.
Structural Performance Testing
MetalZenith conducts specialized testing for structural applications including welding performance evaluation using standard procedures, forming characteristic assessment through bend and impact tests, fatigue strength testing under cyclic loading conditions, and atmospheric corrosion resistance testing in various environmental conditions.
Application Engineering
For building structures, M50 provides exceptional load-bearing capacity and long-term stability. In bridge engineering, its fatigue resistance ensures reliable performance under dynamic loading. For machinery manufacturing, the dimensional stability and wear resistance enable precision structural components. In vehicle construction, the high strength-to-weight ratio optimizes structural efficiency while maintaining safety standards.
