Chromoly Vs Mild Steel Price

For all measurable purposes 4130 and 1018 weigh the same at 491 lbs.

Chromoly vs mild steel price.

And wall thickness a chrome moly tube weighs the same as a mild steel tube. Chromoly 4130 is a low alloy steel containing chromium molybdenum iron carbon and other alloying elements. Chromoly vs titanium or carbon fiber. The addition of chromium to steel improves strength and corrosion resistance and the molybdenum increases material toughness.

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. It was designed for and is used extensively in the aircraft industry due to it s high tensile. The first and most often heard myth is that chromoly is lighter than mild steel this is terribly incorrect. Aluminum on the other hand is more like glass which breaks before it bends.

Chrome moly is the abbreviation for chromium molybdenum and it is an alloy steel. Given the same o d. The elongation values of the docol tubes are better than in the 4130 chrom moly tubes. 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.

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. It fails in a predictable way bending before it breaks. Also steel is reliable. The docol tubes showed a better behavior at fracture compared to the crmo tubes.

It is from this view point that i will present facts to debunk some of the myths between 4130 chromoly and 1018 mild steel chopper frames. 4130 chromoly tubing also has a smooth interior and exterior finish that resists scaling and oxidation. The mechanical properties of the docol 800 dp tubes are very similar to the 4130 chrome moly tubes. The docol tubes have slightly lower yield strength but higher tensile strength.
