Is 4130 Chromoly good for bikes?
Now, there are hundreds of kinds of steel, but 4130 finds its way into bike frames because, among other attributes, of its weldability, formability, strength, ductility and toughness.
Is Chromoly a good bike brand?
A workhorse of the industry, chromoly is a light, strong steel. When it is butted and shaped to take off excess weight, it can deliver a fairly light frame that will last through years of hard use. Chromoly is responsive and offers good flex while maintaining its form.
How long do Chromoly frames last?
Chromoly frames are typically overdesigned well above the endurance (fatigue) limit of 0.54 of tensile strength. This means if the welds are properly done, you can expect what we call ‘infinite life’.
How good is 4130 steel?
4130 steel is easily cold worked, hot worked, and forged, but cannot be aged. It has excellent ductility when annealed and is a through-hardening alloy. 4130 steel performs best as a structural steel, and is most often found as round tube or bar stock in structural applications for aircraft and buildings.
What does 4130 mean BMX?
So in long form, 4130 means an alloy steel with chromium and molybdenum that has a carbon content of 0.3%. One thing to mention about the word “alloy” is that it’s more of broad term explaining the metal material is made of two parts. For example, you might find aluminum alloy for some parts of your bike.
Are chromoly frames heavy?
Chromoly is slightly heavier than aluminum, but the frame can be thinner and has reduced stiffness, which provides a smoother ride.
What is 4130 Chromoly used for?
Applications of 4130 Steel Manufacturing equipment for bearings, vehicle parts, and gears. Rock crushing machinery. Resistance welding products. Drill bits and taps.
What is a chromoly bike frame?
Chromoly is a chrome-alloy steel with a medium carbon content and . 8% – 1.1% molybdenum for strength. 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.
How big is a 4130 chromoly mountain bike frame?

What is 4130 chromoly tubing?
Chromoly 4130 is a low alloy steel containing chromium, molybdenum, iron, carbon, and other alloying elements. The addition of chromium to steel improves strength and corrosion resistance and the molybdenum increases material toughness. 4130 chromoly tubing also has a smooth interior and exterior finish that resists scaling and oxidation.
Is the GT Performer 4130 chromoly bike in good condition?
This auction is for a gt performer 4130 Chromoly bike Bicycle. I do not know too much about bicycles but it looks to be in very good condition. The back tire is busted in a couple places. If you have any questions please email. it is being sold as is as pictured.
