Description
Cr12MoV Round Bars / Flat Bars / GBT T21201 Round Bars
Cr12MoV Round Bars are premium cold work tool steel bars known for their exceptional wear resistance, high hardness, excellent compressive strength, and dimensional stability after heat treatment. This Chromium-Molybdenum-Vanadium Alloy Tool Steel is widely used for manufacturing punches, dies, shear blades, thread rolling dies, cold forging tools, blanking dies, gauges, and precision tooling.
Cr12MoV is a high carbon, high chromium cold work die steel developed to provide outstanding wear resistance, high hardenability, and improved toughness compared to conventional Cr12 tool steel. The addition of molybdenum and vanadium refines the carbide structure, resulting in better fatigue resistance and longer service life.
It is extensively used in automotive tooling, metal stamping, engineering industries, aerospace tooling, and heavy industrial applications.
M/s Textron Steel and Alloys supplies high-quality Cr12MoV Round Bars in forged, peeled, bright, turned, polished, and centerless ground finishes. Our bars are available in various diameters and lengths with complete mill test certificates.
What is Cr12MoV Steel ?
To understand the comparison, we first need to define the challenger.
Cr12MoV material is the Chinese GB standard designation. The code stands for:
• Cr12 : ~12% Chromium (High corrosion/wear resistance)
• Mo : Molybdenum (Hardenability)
• V : Vanadium (Wear resistance)
