Description of the effects of common alloying elements on steel

Another page from my wonderful notes. "Hardenability" is listed for many of the elements.  Hardenability, in general terms, refers to the response of a steel to heat treatment. ie if you have a very low hardenability, heat treating will not have much of an effect on the properties of the steel.




If the list is too general or you have any specific questions, or if you think the list is not useful, please let me know!

Cool notes some of them I knew but could not recall correctly dealing with the differing tube sets and high ends super steels in cycling will give you a quick and dirty metallurgy background.  Though some things look good on paper or in theriory they do not always work out well. ( coloumbus metax .... epic super steel failure)

As for a background what are you looking for? A quick explanation of the mechanism?

something along the lines of: adding Boron causes the formation of very hard Borocarbides which increase the hardness of steel, but alloying with Boron is not common because the range of Boron you can use before the steel gets brittle is very narrow?

I think you misunderstand me i have the background ( I do usually have to brush up these days though) sometimes when discussing a new frame with a customer you have to break down the differing steels from the four major brands for the customers so they do not become blinded by names and hype.   Renolds, Coloumbus, Dedaci, True Temper all make great high end steels and the best builders mix and match ( if compatible to joining process) some companies will also through out tensile strength for a comparrison to Ti. (90k+) Basically all other materials in cycling want to resemble the charasitics and ride quality of steel.

Oops my bad. When I read your email I switched around the words "give" and "you" in my mind  :0002-1239:  :drinkfall:

Interesting that bikes are that advanced into materials!

Bikes and aerospace are the leaders in light weight high strengh material adoption.

Golf clubs are getting pretty crazy into advanced materials as well I'm told

True I forgot about them. I never understood the sport.

golf is trickle down and usually from the cycling industry you will notice that the shafts are usually made by the tubing manufacturers that supply the cycling industry.

cycling and aerospace work hand in hand in had as they both need the same things in steel I 'll post some links of some of the steel companies tomorrow

It really has changed dramatically in the last 5 years steel is far better and is very close in weight now to some of the exotic matriarchs. We use to only have to deal with difference in shape and butting now it is steel make up and propertys.
