Chromoly Steel Rust
What is chromoly steel.
Chromoly steel rust. It is a high carbon content steel which makes it resilient to high heat scenarios and with its abrasion resistance the barrels wear slower over time. Stainless steel types such as 304 or 316 are a mix of elements and most contain some amount of iron which easily oxidizes to form rust. Mostly is just a litte rust on the surface. 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.
4130 chromoly tubing also has a smooth interior and exterior finish that resists scaling and oxidation. With a chromoly steel bike you can worry less about bike upkeep and enjoy riding year after year rain snow or shine. This steel is the most common used today by various militaries including the united states. You can buy it at your car parts shop.
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. These range from applying a coat of a wax like renaissance or johnson s paste wax to simply applying a thin coat of a good rust preventing lubricant like clp breakfree. 4150 or mil spec steel is commonly used in heavy fire applications. 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.
There are many ways to protect a gun from rust. 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 a chrome alloy steel with a medium carbon content and 8 1 1 molybdenum for strength.
I wouldnt worry about holes or failure. The addition of chromium to steel improves strength and corrosion resistance and the molybdenum increases material toughness. The steel used for bikes is a high quality alloy this makes it less easyer to rust. 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.
In short there s no difference between a standard 4130 carbon steel barrel and a chromoly barrel because they re the same thing.
