Chromoly Steel

The addition of lead gives 41l40 the best machinability of all the alloy steel we offer.

Chromoly steel. 4130 is excellent for wear. Certificates with a traceable lot number are available for these products. The alloy can also be hardened by heat treatment. Buy now shapiro metal supply centrally located in st.

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. Chrome moly sheet 4130 chrome moly sheet is a low alloy steel containing molybdenum and chromium as strengthening agents. Chromoly is a chrome alloy steel with a medium carbon content and 8 1 1 molybdenum for strength. Also known as chrome moly steel this versatile 4140 alloy steel is used for a wide range of parts such as gears axles shafts collets and die holders.

It resists fracturing from repeated stress. Chromoly steel is also treated before and after manufacturing to increase the natural resistance to corrosion dramatically lessening the chance of rust. 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. Chromoly 4130 is a low alloy steel containing chromium molybdenum iron carbon and other alloying elements.

41xx steel is a family of sae steel grades as specified by the society of automotive engineers sae. Chromoly is the informal name for 41xx steel an alloying steel that s strengthened with chromium and molybdenum. Steel 4130 chromoly solid rounds sheets and plates and seamless round tubes. The addition of chromium to steel improves strength and corrosion resistance and the molybdenum increases material toughness.

The molybdenum ratio is 0 15 0 25 by weight while the chromium is 0 8 1 1 and the carbon ratio is just 0 30. For technical drawings and 3 d models click on a part number. With a chromoly steel bike you can worry less about bike upkeep and enjoy riding year after year rain snow or shine. Easy to machine 41l40 alloy 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. The carbon content is nominally 0 30 and with this relatively low carbon content the alloy is excellent from the fusion weldability standpoint. 4130 chromoly tubing also has a smooth interior and exterior finish that resists scaling and oxidation. It resists fracturing from repeated stress.
