RE: pressure rating
Max pressure for a class 300 material group 1.1 flange to ASME B 16.5 is indeed 740 psig between -20 to 100F
"what is maximum pressure class rating" isn't clear what you're asking.
I don't think slip on flanges are not normally recommended above class 300 if that's what you mean, but they make them in theory up to class 2500

This is Max working pressure. ASME B 16.5 flanges are good for a hydrotest of 1.5 times this.
There is no difference whether it's a weld neck or slip on flange when it comes to pressure rating.
This is freely available information and I would recommend you obtain a copy of ASME B 16.5 for more information.
