Cr12MoV
Cr12MoV is a classic high-carbon, high-chromium cold work die steel that holds a pivotal position in mold manufacturing and mechanical processing due to its exceptional comprehensive mechanical properties. This product is produced using premium scrap steel as raw material through electric arc furnace smelting and electroslag remelting refining processes. Its precise and controllable chemical composition effectively reduces impurity content while ensuring uniform and dense internal structure. The core features are particularly outstanding: Combining high hardness with exceptional wear resistance, it achieves HRC60-64 hardness after appropriate heat treatment, enabling it to withstand high-intensity friction and impact while extending die service life. Excellent hardenability ensures uniform quenched structure even in thicker cross-sections, preventing defects like uneven hardness. With inherent toughness and temper stability, it resists fractures and deformation during prolonged use, meeting complex industrial processing requirements. Whether for precision stamping, cold extrusion, shearing, or forming applications, Cr12MoV delivers stable performance to reliably enhance production efficiency and product accuracy, making it an indispensable high-quality die steel material in industrial manufacturing.
The Cr12MoV products showcased here come in various specifications to meet diverse processing and application needs. The specific models and technical parameters are as follows:

Surface treatments include blackened, annealed, and quenched states, meeting diverse machining requirements.
- Round steel specifications: Cr12MoV-Φ (diameter) × L (length), with diameters ranging from 5mm to 200mm and standard lengths of 6000mm. Customized cutting is available upon request. Precision grades include standard (±0.5mm) and high-precision (±0.1mm), meeting diverse machining requirements.
- Module specifications: Cr12MoV steel with dimensions ranging from 100×100×100mm to 500×500×500mm, including custom sizes. Forged for precision shaping, these modules feature refined grain structure for enhanced mechanical properties, ideal for large-scale mold manufacturing.
- Implementation standard: GB/T 1299-2014 (National Standard), ensuring product quality complies with industry specifications, with material certification and test reports available.
- Chemical composition (mass percentage,%): C 1.45-1.70, Si 0.40-0.70, Mn ≤0.40, Cr 11.00-12.50, Mo 0.40-0.60, V 0.15-0.30, P ≤0.030, S ≤0.030. The precise proportion of these components is the key to its outstanding performance.
- Heat treatment parameters: Annealing temperature 830-860℃, holding 2-4h, followed by furnace cooling; Quenching temperature 950-1050℃, oil-cooled or air-cooled; Tempering temperature 150-200℃, holding 2-3h. The hardness can reach HRC60-64 after tempering. The heat treatment process can be adjusted according to actual usage requirements.
The Cr12MoV product features a clean and defect-free appearance: The sheet surface is smooth and flawless, with no cracks, inclusions, or porosity. The edges are free of burrs, and the cutting surface is perfectly aligned. Dimensional accuracy is rigorously controlled, with deviations strictly within industry standards. The round steel exhibits uniform coloration without oxide scale buildup, maintains consistent diameter, and shows no significant bending or deformation. The module's forging marks are evenly distributed, and the surface has undergone rough machining to facilitate subsequent precision grinding. The overall appearance boasts an excellent texture, showcasing high-quality manufacturing processes.
Metallographic analysis reveals that the internal microstructure of Cr12MoV steel consists of fine needle-like martensite and carbides, with uniformly distributed and finely dispersed carbides showing no significant aggregation. The average grain size is controlled at 8 or above, effectively enhancing the steel's hardness, wear resistance, and toughness. Through the electroslag remelting process, internal impurities are thoroughly removed, resulting in extremely low occurrence rates of defects such as shrinkage cavities and porosity. The density reaches over 99.8%, ensuring that the steel will not fracture or fail due to internal defects during long-term high-strength use, thereby guaranteeing the stability of mold operation.
- Hardness: The annealed state hardness is ≤255HBW, while quenching and tempering can achieve HRC60-64. The hardness distribution is uniform with a deviation of no more than ±1HRC, effectively resisting friction and wear between the mold and workpiece, thereby extending the mold's service life.
- Impact toughness: αk ≥ 20 J/cm² (at room temperature), maintaining sufficient toughness even at-20°C to prevent mold fracture caused by low-temperature brittleness, meeting diverse regional and operational requirements.
- Wear resistance: Tests show its wear rate is only 1/5-1/3 of ordinary carbon steel. In high-frequency friction scenarios like stamping and extrusion, it maintains mold surface precision while reducing maintenance and replacement frequency.
- Hardenability: The core maintains hardness above HRC58 after quenching at a 200mm thickness, eliminating the need for additional cooling measures, simplifying heat treatment processes, and reducing production costs.
Using high-purity scrap steel as raw material, the process combines electric arc furnace smelting with electroslag remelting for dual refining. By strictly controlling chemical composition and impurity levels, it ensures stable and reliable steel quality. Compared to conventional die steel, Cr12MoV exhibits superior density and uniform microstructure, effectively eliminating material-related die failure risks at the source and providing a solid foundation for subsequent processing and application.
Overcoming the limitation of 'incompatible hardness and toughness', this product achieves high hardness and wear resistance while maintaining excellent toughness and temper stability, meeting multidimensional requirements in complex industrial environments. Whether for stamping dies subjected to high-frequency impacts or forming dies requiring long-term precision, it delivers stable performance. Compared to similar products, its service life extends by 30%-50%, effectively reducing production losses.
Available in diverse forms including panels, round steel, and modules, each configuration offers a wide range of standard specifications. The system also accommodates customized requirements such as irregular dimensions, special surface treatments, and tailored heat treatments, eliminating the need for additional secondary processing. This enables direct adaptation to various mold designs and manufacturing needs, significantly reducing processing time and costs.
Although Cr12MoV is a premium alloy die steel, its pricing offers excellent cost-effectiveness through large-scale production and meticulous cost control. Moreover, its outstanding wear resistance and stability reduce the frequency of die maintenance, extend replacement cycles, and lower both die wear costs and production downtime losses. Over time, this enables customers to significantly reduce production costs and enhance operational efficiency.
Each batch of products undergoes rigorous quality testing, including chemical composition analysis, metallographic structure examination, hardness measurement, impact toughness testing, and non-destructive testing (NDT), to ensure all parameters comply with national standards and customer requirements. Comprehensive test reports and material certifications are provided, with support for retesting by third-party testing institutions, thereby enhancing quality assurance and ensuring customer confidence in product usage.
