15CDV6 yield strength and other mechanical properties

The 15CDV6 grade is a structural alloy chromium-molybdenum-vanadium steel. It is considered an interesting alternative to 30HGSA because the welding is easier. Despite this fact, 15CDV6 / 1.7734 remains extremely resistant to pressure, with good ductility values as well. All that means this particular grade is an excellent material for mass production of heavy-duty machines. It is also worth mentioning that such grades can contain low carbon percentage.

The high strength specifications indicate that a 16-25 mm bar of 15CDV6 alloy has a yield point of more than 930 MPa. The impact strength has a value bigger than 8 KCU, however a larger 25-70 mm bar seems to be weaker in that regard. The hardness (HR) of both remains the same: 321-380. These numbers mean that a 15CDV6 steel sheet is tougher than SAE 4130, for instance. Of course, heat treatment can be applied in order to improve the outstanding properties of this alloy even further.

The implementation of 15CDV6, 1.7734 steel

The above specs show clearly why 15CDV6 steel is a valued commodity in many industries. Even as demanding as the aviation industry, military included. Good toughness alongside impressive elasticity and ease of welding makes it quite prefect for rocket motor casings. The same can be said about lightweight aircraft components, which are supposed to be very resistant to physical abuse at high speeds as well. In fact, nearly all steel parts of a plane can be manufactured from this particular alloy. That means an aero company can use just 1 supplier. Hence, production costs become lower.

Additionally, a 1.7734 grade can be used for the production of roll cages for racing cars or pressure vessels of any kind. The latter can be especially valuable to different science projects or even… the fast-growing private space industry. It also needs tough aero materials, does it not? At this point, 15CDV6 alloys seem to be the best choice for the job.

Soon, even a flyin car should be mass-produced. As a result, the aero markets of all shapes and sizes are pointing their attention towards proper steel alloys. That brings us to a conclusion: the future will be made from 15CDV6, 1.7734 steel and other grades of this type.
