4130 Chromoly Steel Vs Reynolds 725

Heat treating can improve material properties that s heating and cooling the material in a specific way.

4130 chromoly steel vs reynolds 725.

Most cycling steel alloys are based on 4130 chromoly. Reynolds 725 vs 4130. Using an industry standard alloy with mechanical properties similar to our famous 753 brand reynolds mandrel butt and heat treat this alloy so that thinner walls can be used compared to non heat treated steels. The same 0 30 carbon steel chemistry as our 725 range but without the heat treatment process.

In 1897 the company patented the process for making butted tubes which are thicker at the ends than in the middle this allowed frame builders to create frames that were both strong and lightweight. The strength and ductility can be varied by cold working and normalizing if required. How can i save the inputs given to a form in a excel sheet in my pc.

Now go to the most common quality cycletube steel which is 4130 cr mo this has almost identical properties as the old reynolds 531 and is what reynolds 525 and 520 is made of it s also almost certainly what any quality bike manufacturer uses for their own brand or generic cr mo tubing this gives a typical uts of 1110 mpa and a yield. Reynolds 725 vs 4130. 725 can be tig welded and used within our designer select combinations including 853 and 631 tubes. In its 110th year reynolds re launched a limited edition set of 531 tubes for brazed bike frame use.
