Chromoly Vs Steel Axles

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

Chromoly vs steel axles.

They both were same. 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. Heat both pieces of metal red hot and quench them into water the chromoly will become brittle.

Chromoly is a chrome alloy steel with a medium carbon content and 8 1 1 molybdenum for strength. Hi i m going to replace my axle shaft front. In the past i red some topic where it was suggested to use the chromoly axle shafts instead of the rcv front. It was designed for and is used extensively in the aircraft industry due to it s high tensile.

Chrome moly is the abbreviation for chromium molybdenum and it is an alloy steel. There is an acid test you can use to determine the difference. I found the rcv at a very good price with a low delta cost respect to the chromoly alloy. Much of it has to do with heat treating and material composition.

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. 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.

The 7075 shafts are much stronger than the conventional 6061 shafts and have a slightly higher critical speed property. I ground a piece of chromoly and mild steel and there was no difference in spark pattern 2. 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. Made chromoly axles but it.

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. One was no more brittle than the other 3. Given the same o d.
