Old Material Spec A263 Gr 0

[jamesl]

Does anyone have access to A263 spec published in 1950's? I am dealing with some vessels built in 1958. The shell plates were lined or cladded with 405SS per A263 Gr 0. Based on some details on drawing, I think the the liners were attached to the base metal by spot welding.

Yes, I have a 1952 edition of ASTM. Under Process 2. (a) The alloy cladding metal may be bonded to the base metal by any method that will produce a clad steel which will conform to the requirements of these specifications".

Bend Test
Grade 0, Type 405, cold bend 180 degrees
and tension test

metengr,

Thanks.

Based on your reading, did A263 Gr 0 1952 require integrally and continuously bonded cladding?

 

[metengr]

Yes

Adding to metengr's last post, the only problem was there wasn't any easy way to check whether it was bonded or not until you cut it.
Back in those days we had several problems with CS clad with SS.
