what is T45 tube made of?

what is T45 tube made of? i have been on lots of websites and all i have gathered is that T45 is a type of tube (british standard) not a type of material. i really want to find a good data sheet of all the info about this material for finite ellement analysis. i need poisons ratio, ultimate tesile stress, yield stress, and youngs modulous. youngs modulous isnt such a problem since its the same for all steels but all i can find are values of similar materials such as 4130 steel for the others. i guess the figures i have got will do but i would still like to find a data sheet.

i did find a site with some values for yield stress and ultimate tensile stress for T45 but it gave a range not a specific value which i find odd. does this mean the quality of the material varies?

another value i would like to find out is the yield stress after welding but im not sure how to get this.

Boy, it's tough to find anything on T45. The Corus website mentions it along with 4130 (SAE), but there are no product datasheets readily available.

Apparently T45 is a chrome-manganese steel as compared to chrome-moly steel.

If it has the same properties as 4130, then try

I found this, but I don't know how reliable it is. I couldn't find the alloy on Cartech's website.

Contact these guys, they have a detail spec sheet if they sell it.
