Chromoly vs steel.

4130 chromoly tubing also has a smooth interior and exterior finish that resists scaling and oxidation. Which one is better. Steel is the most commonly used material in bike frames. Chromium molybdenum also called chrome molybdenum chrome moly or cr mo and chromium vanadium also called chrome vanadium or cr v are names for two families of steel alloys used in hand tool manufacturing.

Chromoly is a chrome alloy steel with a medium carbon content and 8 1 1 molybdenum for strength. Chromium molybdenum or chromium vanadium steel. When properly manufactured and heat treated they are chemically. 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.

Carbon or high tensile steel is a good strong long lasting steel but it isn t as light as its more high tech brother the steel known as chromoly. 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. 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.

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. 41xx steel is a family of sae steel grades as specified by the society of automotive engineers sae. And wall thickness a chrome moly tube weighs the same as a mild steel tube. 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.

Alloying elements include chromium and molybdenum and as a result these materials are often informally referred to as chromoly steel common variant stylings include chrome moly cro moly crmo crmo cr moly and similar they have an excellent strength to weight ratio and are considerably. 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.
