Comprehensive introduction to 25CrMoVA carbon steel plate

25CrMoVA is a low-alloy, high-strength structural steel known for its excellent combination of toughness, high tensile strength, and wear resistance. It is commonly used in applications requiring high strength and good fatigue resistance, such as in the manufacture of aircraft parts, automotive components, and machinery.

Key properties of 25CrMoVA carbon steel plate:

Composition:

Carbon (C): 0.22-0.29%

Chromium (Cr): 0.80-1.10%

Molybdenum (Mo): 0.15-0.25%

Vanadium (V): 0.08-0.12%

Other elements: Silicon, manganese, and trace amounts of phosphorus and sulfur.

Mechanical properties:

High tensile strength and yield strength.

Excellent fatigue and wear resistance.

Good toughness and resistance to cracking under stress.

Heat treatment:

Can be quenched and tempered to improve its strength and toughness.

Suitable for hardening, and the alloying elements like chromium, molybdenum, and vanadium provide enhanced performance at high temperatures.

Applications of 25CrMoVA carbon steel plate:

- Aerospace Industry:

Aircraft landing gear, engine mounts, structural components subjected to high stress.

- Automotive Industry:

High-performance gears, axles, and shafts.

Crankshafts and connecting rods in racing and performance vehicles due to its high fatigue strength.

- Machinery Manufacturing:

Gears, shafts, and other components subject to heavy loads and frequent wear.

High-pressure and high-temperature mechanical systems such as hydraulic cylinders and pistons.

- Power Generation Equipment:

Turbine blades and components requiring excellent fatigue resistance and toughness at high temperatures.

- Pressure Vessels and Pipelines:

Used in the manufacture of critical components like high-pressure gas containers, and steam piping systems, where high strength and toughness are vital under both ambient and elevated temperatures.

Advantages of 25CrMoVA Steel Plates:

High strength-to-weight ratio: Allows for the manufacture of lighter, more efficient components without sacrificing strength.

Excellent toughness: Maintains good toughness even after heat treatment, ensuring the material doesn't become brittle under stress.

Fatigue resistance: Ideal for parts subjected to cyclic loads, reducing the risk of fatigue failure.

Good wear resistance: Suitable for moving parts and components in contact with other materials.
