As the title suggests, there is a batch of flanges requiring a duplex steel material. The customer demands an pitting equivalent value of >38; which grade would be the best choice? Can A182 F51 achieve it?

Thank you. I checked the standards, and it’s indeed the case. It’s because this material is relatively expensive
