As the title suggests, I would like to ask what the specific meanings of PI, PII, and PIII are, as well as what valve body materials they correspond to. I would be very grateful for your help; those who are currently working in the Sinopec industry are especially welcome to provide insights.

P represents the 18-8 series of stainless steels. PI stands for chromium-nickel-titanium steel, while PII stands for high-nickel-chromium steel
