Doesn't one's textbook have a classification table?

One could look for the AISI/SAE classification schedule.

I don't have a textbook. So I'm looking on the internet. I just want to know what is C, 10, and 40 on the steel given.

try wikipedia.org under "SAE steel grades" I think that answers your question well. (You could have thought of that yourself, but it interested me too. Thanks)
