Chainstay yokes - what thickness? Mountain Bike Reviews good hardness 4130 steel for bottom bracket steel pipe

Heat-treating increases yield stength, higher quality steels can be heat-treated to a higher yield before becoming brittle, 4130 is not considered a very high quality steel since you can only really go up to 130ksi, but 4340 and 300M is and you can go up to 280ksi. Low carbon mild steel can only be surface hardened, so no increase in yield. Chainstay yokes - what thickness?

It has good resistance to

How are the thicknesses of steel tubing different?How are the thicknesses of steel tubing different?Some modern tubes are "triple butted" meaning that there are 3 different wall thicknesses - the thinnest being in the middle. Forming and welding the tubing affects the properties of the steel, so tubing is often "heat treated" i.e. heated to a specific temperature and cooled at a controlled rate, to minimise these effects.Steel Frame Tubing - Fact and Mythology Velo Duo Cycles How does a lugged steel frame compared to weld? Road good hardness 4130 steel for bottom bracket steel pipe

All tubing used in the construction of steel bikes (other than stainless) is a type of 4130 chromoly. 4130 is a general class of steels, based on the content of the alloying elements. The different types of alloys allow for higher strengths, allowing for thinner tubing

Which is better 4130 or 853 chrome moly?Which is better 4130 or 853 chrome moly?853 has a much higher Ultimate Tensile Strength than 4130. Typically 190 KSI vs. around 120 KSI (about 50% greater). 853 has a strength to weight ratio close to Ti! Because the air-hardened joints Increase in strength after welding, the overall stiffness of the frame is increased substantially (30% greater than 4130 Chrome-Moly is typical).4130 Chromoly vs. Reynolds 853 Steel Cycling Forums Which is better 4130 or Reynolds 853 tubing?Which is better 4130 or Reynolds 853 tubing?Butted tubing is more difficult to come across in larger diameters and lengths that are most oft used in bents.

What Is 4130 Chromoly and Heat Treating - BMX UNION

Essentially, 4140 chromoly is harder / stronger than 4130 due to the increased carbon. However, it also comes with a slightly higher price tag and that additional hardness and strength is not necessary for most applications in BMX. Heat-Treating Heat-Treating is a term that goes hand in hand with 4130 chromoly very frequently in BMX.
