15CDV6 1.7734 High Strength Steel Tube Low Alloy Steel Pipe For Racing Frame
Material
15CDV6 is a high-strength low-alloy steel with excellent mechanical properties and toughness. It can achieve the best balance in strength, fatigue resistance and weight, so it is very suitable for making racing structural steel pipes such as racing roll cages and frames.
Specification
- Steel Grade: 15CDV6 / 1.7734
- Standard: EN 10083-3 low alloy carburizing steel
- Dimensions: We can customize the outer diameter, wall thickness, length, etc. of the steel pipe according to the customer's drawing requirements.
- Surface treatment: We can provide hot rolling, cold drawing.
Key Features
- High tensile strength and yield strength, suitable for racing car structures
15CDV6 has excellent toughness and fatigue resistance under load conditions
Although it is very strong, it can also be welded and processed
Vanadium is added to the chemical composition of the steel pipe to increase strength
Corrosion resistance
