In our project we have requirement of Zinc-Plating / bichromate-treated on bolting in carbon steel & P11 piping class.
Now Max. Design Temp in P11 piping classes is 405 DegC & 200 DegC in carbon steel classes.
I want to know the max temperature upto which zinc plated bolting can be used & if zinc plating is not suitable for this temp other alternative plating type.
Thank you for your kindly help.
Kind Regards,
Vijay Kadam
