Chromoly Vs Mild Steel Chassis

It s lighter and stiffer than steel but it s also more brittle and easily damaged.

Chromoly vs mild steel chassis.

Aluminum is the second most commonly used material for bicycle manufacturing. It will still save your life if done right. If it is mild steel then i have to rebuild the whole thing. When cost is a factor as for most of us mild steel is a good choice.

Chromoly is slightly heavier than aluminum but the frame can be thinner and has reduced stiffness which provides a smoother ride. 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. If it s chromoly then i just have to replace a couple of struts and add more to my roll cage to bring it to specs. 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.

If anyone has a viable answer please let me know. 4130 is better due to the amount of weight savings you can have with it. With dom 4130 and docol being the most common as many sanctioning bodies do not allow mild steel erw. So if you run a comp buggy 4130 is the way to go.

In a trail rig like mine i will be using mild steel and a mig. One of the never ending topics of conversation is the use of 4130 steel over mild steel in professional drag racing builds.
