At what normal operating temperature would stress corrosion cracking become a concern for typ 304L and 316L stainless steel? What is the standard protection required to prevent stresss corrosion cracking of vessel heads at this temperature?
How should an engineer approach ASME Boiler Pressure Code external pressure calculations that go outside the range of the charts in Fig 5-UHA-28.1? The condition that exceeds this chart for 304H material is 1300F.
