4130 Chromoly Vs Stainless Steel

Chromoly falls under the the aisi 41xx designations and it is important to be aware of the different properties and applications of chromoly steel when deciding which material you need.

4130 chromoly vs stainless steel. 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. 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. There are 31 material properties with values for both materials. So in long form 4130 means an alloy steel with chromium and molybdenum that has a carbon content of 0 3.

Chromoly steel is actually alloy steel grade 4130. 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. Aisi 316 stainless steel vs. This alloy is generically called chrome moly chromoly crmo cromo chromo and most quality steel frames use a variant of chrome moly.

For example you might find aluminum alloy for some parts of your bike. Aisi 4130 chromoly steel uns g41300 aisi 4130 steel uns g41300 also known as 4130 chromoly steel is a chrome molybdenum series low alloy steel with high strength toughness and hardenability usually used in quenched and tempered condition. Properties with values for just one material 5 in this case are not shown. They have 69 of their average alloy composition in common.

Integrated 4130 chromoly head tube. The 30 at the end of the grade number designates that it has approximately 0 30 carbon by weight. Chromoly 4130 is a low alloy steel containing chromium molybdenum iron carbon and other alloying elements. Both aisi 316 stainless steel and annealed sae aisi 4130 are iron alloys.

This principle of engineering frames to use less of a stronger stiffer material is true for all frame materials. They have a very high 98 of their average alloy composition in common. 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. There are 31 material properties with values for both materials.

The materials themselves are not lighter it is the way they are used that allows the builder. Both sae aisi 1020 steel and sae aisi 4130 steel are iron alloys. 4130 chromoly tubing also has a smooth interior and exterior finish that resists scaling and oxidation. Sae aisi 1020 steel vs.
