New York, July 23.
A new stainless steel alloy which resists salt-water corrosion and has a toxic effect upon barnacles has been patented here, Licences are being issued for its manufacture for use principally in the hulls of all types of ocean-going vessels, The alloy is known as "silver steel." Its unique properties are due to the addition of between 1 and 2 per cent, of silver to common stainless steels containing nickel and chromium.
The silver forms a film of silver chloride on the surface of the steel. Silver chloride is not soluble in water, and therefore serves to protect the metal from the destructive corrosion that has been found to at. tack other stainless steels when used in salt water.
Barnacles and other living water organisms, it is claimed, are poisoned by the silver chloride. ' Vessels with silver steel hulls, therefore, will not need to be drydocked for scraping even after the longest voyage—Reuter, London, July 23—Major C. R. Attlee, Leader of the Opposition, who underwent a major operation on June 20, left the nursing home today. He is not expected to return to the House of Commons until after the summer recess.—Reuter.
