Technical Specifications
Product Overview
Metallurgical Characteristics
JIS DC53 is a high-carbon, high-chromium cold work tool steel with exceptional wear resistance and toughness. The steel's microstructure consists of tempered martensite with uniformly distributed carbides, primarily chromium and molybdenum carbides, which provide superior wear resistance. The addition of vanadium forms fine vanadium carbides that enhance hardness and wear properties while maintaining excellent toughness.
Heat Treatment Process
MetalZenith's optimized heat treatment process begins with stress relief annealing at 650-700°C. Hardening is performed at 1000-1030°C in a controlled atmosphere, followed by oil or air quenching. Tempering is conducted at 150-200°C for maximum hardness (60-62 HRC) or at higher temperatures (300-500°C) for improved toughness applications. Our precise temperature control ensures consistent microstructure and properties.
Manufacturing Process
Production begins with electric arc furnace melting followed by ladle refining and vacuum degassing to achieve optimal cleanliness. The steel is cast into ingots and hot forged to break down the cast structure. Subsequent hot rolling and controlled cooling create the desired microstructure. MetalZenith's advanced processing includes ultrasonic testing, magnetic particle inspection, and dimensional verification to ensure product integrity.
Quality Standards & Testing
Every production batch undergoes comprehensive testing including chemical analysis by optical emission spectroscopy, mechanical property verification through tensile and hardness testing, and microstructural examination. Dimensional inspection ensures compliance with specified tolerances. MetalZenith maintains full traceability from raw materials through final delivery, with complete documentation provided per EN 10204 standards.
