A350 Flanges

A350 LF2 is a carbon steel fitting material, very similar to A105, that is used in general industrial applications and can withstand continuous service down to -46F. This material is supplied in a normalized condition and the Charpy V-Notch tested at -50F.The Charpy testing is used to reveal a materials natural ductile to brittle transition as temperature decreases. A test sample is brought down to temperature, notched and then struck by a pendulum device. The device measures the amount of energy absorbed by the material until failure occurs
