Need information on B4A26 Steel? Can anyone assist?

[jabce85]

I can't find any info on this type of A26.. can anyone help me out? Thanks in advance!

Maybe it's because the ASTM A26 steel specification was withdrawn in 1966 and replaced with ASTM A551/A551M.

Thanks for the reply Mech_Engineer. I saw that link earlier today, but the 'tires' bit through me off... Not to divulge too much info, but I do find it odd that an aircraft company would be using a "withdrawn" standard.

Is there anyone else who might have a more definitive answer? I'm just looking for all the info I can get.

Thanks for the interest thus far.

I looked on the internet and found only one shop in the US that supplies B4A26 Steel products.

Althought the B4A26 was withdrawn, it is superceded by ASTM 551/551M, internally to the vendor, the specs should be the same. Tires would refer the 'wheels' for railcars/vans.

If a customer is using B4A26, then I'd recommend comparing the customer specs with the ASTM spec 551/551M to see if they are the same.

Thanks for the reply, Astronuc.

That's pretty much the same conclusion I came up with. I already contacted that one shop, but I just wish there was some more technical info on this material directly. (A profile for it on MatWeb would have been nice.)

Thanks for the replies!

I checked MatWeb and I didn't find ASTM 551 grade. It's best to get the product specs from the supplier.

One should remember that specs are generally quite broad, primarily to allow product acceptance. With respect to performance in the field, one should use the appropriate values from the product certification.

MatWeb lists AISI 8620 as roughly equivalent to ASTM A551 steel, so you could probably get a general idea of what you're working with there. To get real data on the standard, you'll have to get your hands on the ASTM A551/A551M spec.

Thank you sir. I will go this route if I can't get any info back from our customer about the material.

If I do get specs for the material (and they're not proprietary) I will post them on here and also see if I can get them on MatWeb.

Cheers.
