sae material specification

Can anyone out there help? I am currently trying to wade through a
large pile of prints that are all from a Japanese company. If anyone
else has ever dealt with prints from Japan you understand my pain. We
(USA) don't seem to see eye to eye on how drawings should be
structured. Anyway here is my question. I have a part that needs to
be recreated and I am clueless about what type of material it was
previously made from. All the drawing says is SAE590700 as the
material. Does anyone know what these are or were I can find out what
it is? 1018, A-2, 4140, 6061 ?????

 

is it first angle or third angle projection? that is always fun...

the drawing says, "SAE590700". does the 'SAE' signify tha the material
has already been converted from something to what we can understand?
have you googled the SAE number?

p.s. congratulations on sinking that sub

 

One place to look is in the back of a Misumi catalog if you have one
handy... they have a list of JIS standard steels and what the American
equivalent is...

Good idea, but not any help in this case. I have never looked in the
back of the Misumi catalog until today................. there is some
good stuff back there. Thanks for the infoz.

 

Please recheck the number. Spaces, dashes, letters/numbers ...

 

Do a search for SAE 5907 steel... that appears to be what you are
searching for... In regards to the misumi catalog, the Metric catalog
has more reference goodies in the back compared to the English
catalog... hope that helps...

I can help you out with one of the numbers. 4140 is Pre-heat treated
shafting steel used as standard steel for precision ground revolving
shafts of all types, from high speed hydrostatic and magnistatic
spindle shafts, to high quality cam and crank shafts. It has been the
concensus most widely used throughout the machine and tool industry for
many years. With regards to the other numbers, I would suggest that
you obtain any steel company's heat treating hand book, (given out
free), and look up the numbers. You might want to go online and look
up Crucible Steel, Carpenter Steel, Ackerlind Steel, Bethlehem Steel
and many more, and eventually you will run across the numbers and their
complete description of properties, etc. I am sure that the Japanese
steel manufacturers offer the same courtesy to their accounts.

Good luck,
