ZG18 cast steel

[tandemloc]

Looking for help. I have a material cert for a cast part that states that the material complies with material grade ZG 18. As near as I can tell based on chemical and physical properties it is very close to A27 70-40. Getting answers from the chinese manufacturer is very difficult. Can anyone tell me for sure of a US equivalent?

No I had not heard of it before. THanks for posting the link. I poked around on the free stuff and didn't get any results. We generally use mild steel for everything we do so I don't know if I want to spend any money signing up for software I will likely rarely (if ever) use.
