X4111 STAYBRITE SHUTTERS. ------------------- The condition which I referred to as "descaled" is obtained by pickling the material in a hot mixture of hydrochloric and nitro acids. If you would let me have two or three of the shutters, I would have them treated for you, so that you could try them for yourself to see that they did not retain grease marks. I should not anticipate that either asand blasted or scratched material, whether the scratching was produced by emery or a wire brush, would be likely to retain their condition, as either of these actions result in surface stresses which are liable to set up corrosion, even in Staybrite. I am asking BY/EM. to see you, so that you can hand him some pieces for us to treat. BY.{R.W. Bailey - Chief Engineer} By | ||
