Product Description:
15CDV6 is a low-alloy steel that contains a combination of carbon, chromium, vanadium, and molybdenum, making it a highly versatile material used primarily in the aerospace, automotive, and high-performance engineering industries. It is designed to offer excellent hardenability, strength, toughness, and resistance to wear and fatigue. 15CDV6 is often used for parts that require high mechanical properties, including gears, shafts, and structural components, especially where both strength and toughness are crucial.
Features:
- Excellent Hardenability: 15CDV6 has good hardenability, which allows it to achieve high strength and wear resistance after heat treatment.
- High Strength and Toughness: It offers a good balance of strength and toughness, making it suitable for components that need to endure heavy loads, shock, and mechanical stress.
- Fatigue Resistance: The alloy has good fatigue resistance, making it ideal for parts subjected to repetitive loading conditions, such as gears and shafts.
- Wear Resistance: The vanadium and chromium in the steel provide excellent wear resistance, even under high friction and wear conditions.
- Good Weldability: 15CDV6 can be welded using standard welding techniques, making it versatile for manufacturing processes.
- Impact Resistance: The material offers good impact resistance, allowing it to withstand sudden shocks and heavy loads.
Specifications:
- DIN 1.7734: German standard for this low-alloy steel, which includes 15CDV6.
- AISI/SAE equivalent: Similar to AISI 4140 and AISI 4150 steels but with different alloying elements.
- ISO 683-1: This international standard provides specifications for low-alloy steel used in applications requiring high-strength properties, which includes 15CDV6.
