Chromoly steel is relatively lighter compared to other types of steel. It is known for its high strength-to-weight ratio, making it a popular choice for applications where both strength and weight are important considerations, such as in bicycle frames or roll cages for race cars.
Steel hasn't a chemical equation.
That's not a test for any particular alloy at all, only a rough guide to two metals' relative hardnesses. Mild-steel cannot be hardened through, only case-hardened to give a thin, wear-resistant surface layer. Heat-treatable steels can be hardened through but hardness alone merely tells you it has been hardened, and may simply be high-carbon steel (Iron plus a small amount of carbon). If you know the metal in a particular machine can only be either untreated mild-steel or Chromoloy, then hardness will differentiate them; but if you don't know what alloys have been used, it tells you only which components have been hardened, and could be any of two or more such alloys in the machine. As for using a file as a hardness-tester.... Not with any file belonging to me or anyone else who respects their tools, you don't!
It depends on multiple factors, There are multiple grades/alloys of both that have different characteristics ( flexibility, temperature ranges, chemical resistance that affect it's strength). If you are going by volume, comparing pieces of the same width/length/thickness, than steel is always stronger. If your comparing by weight, comparing 2 pieces that weight the same, than aluminum is almost always stronger with the exception of chromoly steel. 41xx grade chromoly steel is the only steel that is stronger/weight than aluminum alloys(debatable), but most agree that the aluminum of similar weight will be stiffer. Aluminum alloys usually show a 1/3 weight saving with equal strength vs. non Chromoly steels, like that used in production cars. All commercial planes are made of aluminum alloy.
most often a firearm's barrel will be made with high quality steel. In some special cases the barrel will be chrome lined or will be made with stainless steel. both of which are used to prevent corrosion, expand the life of the firearm's barrel and to make cleaning easier.
Modern light switches are made from plastic, copper, and (maybe) coiled steel springs.

People do it all the time, but you have to bake the metal to release the hydrogen after you do it. Otherwise the steel gets brittle.

Yes, the Mike Spinner Hyper Pro model features a chromoly frame. Chromoly steel is known for its strength and durability, making it a popular choice for high-performance BMX bikes. This frame construction helps provide a balance of lightweight performance and resilience during tricks and jumps.
Generally speaking aluminum frames have larger diameter tubes than steel or titanium bikes, but the most obvious is to test with a magnet. If it sticks it's a steel frame. If it doesn't it's probably aluminum. Titanium frames are still so rare that you are very unlikely to buy one w/o knowing.
Chromoly (often spelled cromoly) is an abbreviation for "chromium-molybdenum steel". Chromoly is an alloy used to produce tubing for bicycle frames and race-car roll cages. It is not as lightweight as some steel alloys, but has the advantages of high tensile strength and malleability. It is also easily welded and is considerably stronger and more durable than standard (1020) steel tubing. It is also known as 4130 steel, and is composed of 0.28 to 0.33% carbon, 0.4 to 0.6% manganese, 0.8 to 1.1% chromium, 0.15 to 0.25% molybdenum, 0.04% phosphorus, 0.04% sulfur, and 0.2 to 0.35% silicon, in addition to iron.

I think a freestyle bmx should be made out of steel but I've heard bmx's are made out of chromoly or alluminion, i hope that's just for racing
Chromoly is stronger in terms of tensile strength and both metals are about the same in yield or bending strength.
Offroad go-kart chassis are typically constructed using chromoly steel tubes, specifically 4130 steel, due to its high strength-to-weight ratio and durability. This material provides the necessary rigidity to withstand rough terrains while keeping the overall weight low. Alternatively, mild steel, like DOM (Drawn Over Mandrel) tubing, may also be used for budget-friendly builds, but it is heavier and less resilient than chromoly. The choice of steel ultimately depends on the desired performance, weight, and cost considerations.
chromoly is used in are daily life by riding bikes in a bike we also use it in cars so it could look shiny. its used in bikes cars
Wall thickness is about one mm.
