Chromoly Vs Steel Axles

The 7075 shafts are much stronger than the conventional 6061 shafts and have a slightly higher critical speed property.

Chromoly vs steel axles.

Chromoly steel is a type of low alloy steel that gets its name from a combination of the words chromium and molybdenum two of the major alloying elements. One was no more brittle than the other 3. I found the rcv at a very good price with a low delta cost respect to the chromoly alloy. By using lighter weight materials that have good stiffness characteristics the rpm capability is also increased.

The chromium adds strength hardenability and a level of corrosion resistance to mild carbon steel though chromoly is not as corrosion resistant as stainless steel. Also in the nickel chromium molybdenum group this low alloy lower carbon grade isn t viable for drive axles tensile strength is about half of the 1040 material typically used for oe. Much of it has to do with heat treating and material composition. Made chromoly axles but it.

There is an acid test you can use to determine the difference. And wall thickness a chrome moly tube weighs the same as a mild steel tube. Which are the benefits to use the chromoly instead of the rcv. Given the same o d.

It was designed for and is used extensively in the aircraft industry due to it s high tensile. The practical thought process is that steel is the strongest and most cost effective material. Chromoly is a chrome alloy steel with a medium carbon content and 8 1 1 molybdenum for strength. A common misconception is that chrome moly is lighter than mild steel.

Chromoly steel is often used when more strength is required than that of mild carbon steel though it often comes at an increase in cost. Hi i m going to replace my axle shaft front. They both were same. I ground a piece of chromoly and mild steel and there was no difference in spark pattern 2.

In the past i red some topic where it was suggested to use the chromoly axle shafts instead of the rcv front. Chromoloy tubing is made from a family of low alloy steels that contain chromium and molybdenum sae 4130 or 4140 along with the iron carbon and other elements. You may pay a little more for u s. It is a steel that is stronger than carbon steel more commonly used in bike manufacturing so we can use thin wall tubing giving you a lightweight frame that will last through years of riding.

Imported chromoly axles tend to differ from those made in the u s.
