I am looking for the published ASTM chemical specifications for Class 30 grey iron.

Thank you

I was hoping for the free version

RE: Class 30 Grey Iron Chemical Specifications

Sorry, actually ASTM A48 only specifies properties. There is no defined requirement for chemical composition. Typical composition can be found in this document:

There is no free version of copyrighted materials.
If you use these in business then the liability of not owning them is huge.

Join ASTM. You get a free volume as a member (membership is cheaper than the book).
And you can vote on ballots by email, so no meetings to attend.

RE: Class 30 Grey Iron Chemical Specifications

Good comments by all.Class 30 is based on mechanical properties, depending on the casting size , configuration, melting practice etc, chemistry will have to be suitably altered.

You may need to add some Mo up to 0.5% to attain your tensile strength.
