Does anyone here know the modern equivalent of this grade? Our supplier doesn't know and I've googled it to death without luck! It's for a turbine exhaust duct and the drawing is early-mid 70's.
Hi, we have a section of turbine exhaust ducting to make, the original (old) drawings specify this grade, and the customer requires the same or equivalent grade. I've found EN 10028-7 that covers it, but I've drawn a complete blank on finding the actual equivalent grade. If anyone can help out...
