A coding issue with Neway valves

There is promotional material for Neway valves, showing that the gate valves and valve stems used in acidic environments have the letters NC on them. Does anyone know what this means? For example, regarding the valve stem specification A182 - F6a - NC, I searched on Baidu for a long time but couldn’t figure out what NC means. What kind of coating treatment is it?

Considering that the valve is used in an acidic environment, NC should indicate that the material meets the NACE MR 0175 standard.

I can see that you not only have a good understanding of operating conditions, but also know a lot about valve materials and standards
