There is now a ball valve requirement that the valve body be made of 310 stainless steel, in accordance with national standards. After checking GB/T 12230, I found that it lists only 316 cast steel, not 310 cast steel. How should I deal with this? I would appreciate some guidance from experts, thank you!

Why must it be 310? Is it in a high-temperature operating condition?

Per ASTM A743-CK20

The temperature isn’t very high either, it’s just 200°

The 310 casting grade is CK20

It’s made of material 2520; it can withstand temperatures up to 1000 degrees

I am a valve designer; I choose NB/T 47010 S31008

310 has only advantages in terms of corrosion prevention for seawater-based substances
