Heat treatment of Front Pivots.

Hs{Lord Ernest Hives - Chair}12/B34114.

With reference to heat treatment of the Front Pivots.
I am agreed that the temperatures 800°C and 540°C are probably good and safe ones.

I am also pleased that our heat treatment generally turns out to be more regular and consistent than that we get from outside.

R.{Sir Henry Royce}
