Product Description

AWWA C207 CLASS E Hub flange
 

A high mechanical stress increases the risk of high temperature in our AWWA C207-18 Class E Inconel Hub Flange by increasing the hydrogen diffusion rate, crack initiation and propagation in the material. In this AWWA C207-18 Class E Hub Flange, cracks tend to propagate in the embrittled ferrite phase and arrest at ferrite austenite phase boundaries.

Susceptibility to high temperature in our AWWA C207-18 Class E Duplex Steel Hub Flange significantly increases with increasing austenite spacing, where coarse - grained microstructures are therefore more susceptible. Alloy 20 AWWA C207-18 Class E Hub Flange are useful when aeration is not present (oxygen helps protect steel under such conditions).
