Roll Cage Materials

[OutCell]

Hello,

Well i am trying to conduct an FEA on roll cages. I found that the usual materials used for Roll cages (According to FIA regulations+not) were:

1) CDS Carbon Steel

2) ERW Mild Steel

3) DOM Mild Steel

4) Cr (Chrome Molybdenum) Steel

Now i was searching for more info on the specific properties and specs on these but i could only find AISI 1018 steel which i think is CDS?

Anyone knows the specific material+properties used or more information for these 4 that is used in Roll Cage making?


I tried looking on MatWeb, but the results are all general and got me confused a little. Please help me out

thanks

The previous standard material was Chromemoly. Now its DOM mild. CM requires very specific welding techniques, heats, and other procedures which makes it strong, but easy to mess up. DOM is almost as strong, but requires no special welding techniques, so its the new go-to choice.

Try www.eng-tips.com. Its a forum strictly for engineers, so expect to be banned if you're not, but a search will probably turn up some info.

Thanks curtis, i am confused with all the numbering related to these materials so was trying to know the specific naming/numbering for materials used in roll cage making..

It is hard to get a reply on eng-tips

I don't know what the specific properties are for those generic names, but once you figure it out a good source of material information is the Metallic Materials Properties Development and Standardization (MMPDS) document. An older version is available for free here:

It is targeted towards aviation so it may not have all the answers, but you may still find it helpful.

Thanks Alastor

I use MatWeb.com and eFunda for material properties table
I downloaded the PDF, will take a look at it, thanks
