Technical Specifications
Product Overview
Metallurgical Characteristics
CPM S30V is a martensitic stainless steel produced through Crucible Particle Metallurgy (CPM) technology, which involves rapid solidification of molten steel into fine powder particles followed by consolidation. This process results in a uniform distribution of fine vanadium carbides throughout the steel matrix, providing exceptional wear resistance and edge retention properties.
Manufacturing Process
MetalZenith employs advanced powder metallurgy techniques including gas atomization, hot isostatic pressing (HIP), and controlled atmosphere processing. The steel undergoes vacuum melting to ensure cleanliness, followed by rapid solidification to achieve fine carbide distribution. Subsequent consolidation processes eliminate porosity and achieve full density.
Heat Treatment Procedures
Annealing: Heat to 870-900°C, hold for 2-4 hours, cool slowly to achieve 255-285 HB hardness. Hardening: Austenitize at 1065-1095°C, quench in oil or air to achieve maximum hardness. Tempering: Temper at 150-540°C depending on desired hardness and toughness balance. Multiple tempering cycles may be employed for stress relief.
Quality Standards & Testing
All CPM S30V products undergo comprehensive quality control including chemical analysis by optical emission spectroscopy, hardness testing per ASTM E18, microstructural examination, and dimensional verification. MetalZenith maintains traceability records for each heat and implements statistical process control to ensure consistent quality. Products comply with international standards and customer-specific requirements.
Corrosion Resistance & Performance
The 14% chromium content provides excellent corrosion resistance in mild environments, while the high vanadium content (4%) forms hard vanadium carbides that contribute to superior wear resistance. The steel exhibits excellent edge retention and can maintain sharpness significantly longer than conventional tool steels, making it ideal for premium cutting applications.
