Which is the better steel for a frame: Reynolds 520 or Reynolds 4130? Thanks.

Same alloy
Good to know. If the alloy is the same, though, what's the difference between 520 and 4130?

520 is the proprietary designation for a range of butted frame tubes made by Reynolds using a chromium molybdenum steel alloy similar to the AISI 4130 standard.
Other manufacturers also make butted frame tubes of AISI 4130 chromium molybdenum alloy.
The raw material used for Reynolds 520 is essentially 4130, so the difference between 520 and 4130 is that 520 refers to the finished tube sets from Reynolds, while 4130 is simply a steel alloy that other manufacturers use to make their own tube sets competing with Reynolds 520.

Not just similar, but actually 4130.
Here's a quick inside tip for people wondering about exotic, custom compositions of steel. They don't exist. Unless you go to a welding filler rod manufacturer like ESAB, well, infact, only ESAB really, or have a custom 100lb heat made in a research department's electric melting facility, you won't get a 200 tonne steel mill to make you a damned thing that isn't an internationally accepted, standardised steel. They do this for various reasons:
1.) No-one but you wants it
2.) It's not a standardised steel, so no-one has any idea how to heat-treat it (They like to work from fifty year old Jominy tables). So no-one but you wants it
3.) It's mechincal properties, fracture behaviour and - most important to contruction - welding behaviour are unknown so no-one but you wants it.
See a pattern?
Even the brand new Reynolds 953 is in fact disguised Carpenter Custom 455, which is a thirty-year old standard precipitation hardenable 455-grade stainless steel.

Thanks, Falanx. I thought so, but decided to hedge a little. :p
