Chromoly Vs Steel Axles

And wall thickness a chrome moly tube weighs the same as a mild steel tube.

Chromoly vs steel axles.

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. I found the rcv at a very good price with a low delta cost respect to the chromoly alloy. They both were same. You may pay a little more for u s.

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. 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. Much of it has to do with heat treating and material composition. Made chromoly axles but it.

In the past i red some topic where it was suggested to use the chromoly axle shafts instead of the rcv front. What is chromoly steel. The practical thought process is that steel is the strongest and most cost effective material. A common misconception is that chrome moly is lighter than mild steel.

Chrome moly is the abbreviation for chromium molybdenum and it is an alloy 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. The 7075 shafts are much stronger than the conventional 6061 shafts and have a slightly higher critical speed property. Given the same o d.

By using lighter weight materials that have good stiffness characteristics the rpm capability is also increased. Hi i m going to replace my axle shaft front. It was designed for and is used extensively in the aircraft industry due to it s high tensile. Chromoly is a chrome alloy steel with a medium carbon content and 8 1 1 molybdenum for strength.

There is an acid test you can use to determine the difference. Heat both pieces of metal red hot and quench them into water the chromoly will become brittle. Imported chromoly axles tend to differ from those made in the u s. Which are the benefits to use the chromoly instead of the rcv.

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.
