Cr12MoV Plate

Cr12MoV Steel Plate is a high-performance cold-work die steel characterized by exceptional hardenability, high hardness, superior wear resistance, and high strength. Its chemical composition includes carbon (C), chromium (Cr), molybdenum (Mo), and other alloying elements. It is typically used to manufacture large, complex cold-stamping dies, shearing dies, deep-drawing dies, and precision measuring tools that withstand heavy loads. Its overall performance is superior to that of Cr12 steel.

Basic Information & Characteristics

• Material Type: Cold-work die steel.

• Main Elements: Carbon (C) approx. 1.45%–1.70%, Chromium (Cr) approx. 11.00%–12.50%.

• Key Features: Excellent hardenability, high post-quenching hardness, strong wear resistance, and high strength.

• Performance Advantages: Compared to Cr12 steel, Cr12MoV offers enhanced hardenability, hardness, wear resistance, and mechanical strength.

Typical Applications

• Heavy-Duty Tooling: Used for cold-stamping dies, blanking dies, and trimming dies with large cross-sections, complex shapes, and harsh working conditions.

• Forming Dies: Used for manufacturing flanging dies and deep-drawing dies for steel plates.

• Precision Tools: Also used for circular saws, standard tools, gauges, and thread rolling dies.

Heat Treatment (Example)

Common processes include preheating, heating to approximately 1050°C, followed by step quenching at 620°C, oil cooling, or bainitic isothermal quenching. Subsequent tempering at 520°C (multiple times) is performed to achieve the required hardness and toughness.

Executive Standards

Complies with the Chinese National Standard GB/T 1299 (including historical references such as GB/T 1299-1985 and updated versions like GB/T 1299-2014
