Materials specs and properties
(OP)
Hi folks first post beers on me!.
I have been handed a note from my manager asking for some info on:-
1 A Cast Iron the grade on the drawing is 500/7 and a supplier has recommended 600/3. What do these numbers mean please? Or where can I find a table of properties etc? I'm not sure of composition for this one.
2 We have a 'Unified Number' for a carbon steel it is G10210, although I have an list of ASTM numbers Boss wants a BS number or cross ref list (for both). Composition is
C 0.18-0.23
Mn 0.60-0.90
P 0.04 max
S 0.05 max
Thanks

G10210. If you don't have the internet
then try 1021.
Not know the size and purpose of what your
looking the web site will help you better
and you can print out the information
you need.

RE: Materials specs and properties
I have a question for you regarding the cast iron designations. Are you sure that they aren't supposed to be:
60-03
and
50-07
The reason I am asking is because ASTM A 536 Standard Specification for Ductile Iron Castings references grades as follows:
80-60-03, which means 80 ksi tensile strength (550 MPa), 60 ksi yield strength (410 MPa), and 3% minimum elongation. 70-50-05 is the next standard grade, then 60-42-10.

Thanks again.
RE: Materials specs and properties
In any case, I think that TVP and arunmrao are correct, and that the numbers refer to ductile (aka nodular, aka spheroidal) iron, a grade of cast iron containing additives that make the graphite clump into round aggregations. PrImpEng, if you check with a local iron foundry, they should be able to enlighten you on the callout choices.
Good luck!
