Class 30 Grey Iron Chemical Specifications

[dshore]

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

Thank you

Lucky for you ASTM has published this information in ASTM A48 / A48M - 03(2012) Standard Specification for Gray Iron Castings:

I was hoping for the free version

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.

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.
