4130 Chromoly vs. Reynolds 853 Steel Cycling Forums

Aug 07, 2003 · 853 has a higher strength to weight ratio, has better fatigue strength and stiffness (about 30% greater than 4130). 853 is still Reynold's best steel. The joints actually gain strength as they cool. 853 cannot be brazed, only welded. Reynolds makes a 4130 called Reynolds 525. It's a general all-purpose tube - less expensive than 853. R2

Ultimate tensile strength indicates the maximum stress that a material can withstand while being stretched or pulled before breaking.

Compression Force on square tube Engineers Edge

Jul 26, 2016 · Can someone give some pointers on how to calculate the compression force of a steel square tube 4" tall x 2" wide x 0.125" wall thickness. I would like to know how much weight can be applied before the steel tube begins to deform. However, everywhere I look, I only see numbers for tensile strength and I'm not sure if this is completely applicable here.

DOM Tubing - Miller Welding Discussion Forums

The higher strength of the 4130 allows a thinner wall tube to be used. I would stick with NHRA wall thickness/O.D. recommendations shown in their rulebook. I would prefer the DOM tubing like is commonly used in NASCAR. It has good ductility in a crash. ( remember , higher tensile also means harder ) and is readily MIG welded.

Steel Tubes and Pipes what are the main differences

A tube is measured with the help of exact outside diameter (OD) with a set range of wall thickness. The wall thickness is vital as the tubes strength is dependent on it. On the other hand, we measure a pipe by using a nominal outside diameter. The most important property is Strength of Square Steel Tubing Physics ForumsDec 17, 2012 · If your tube is purely in tension or compression due to a load applied axially, then the stress = applied force / area of the tube. Note that the area of the tube is not 1.5 x 1.5, but the area of the metal only. If your tube has a bending moment or a twisting moment applied, then different formulas will
