STAINLESS METAL.

Sheffield metallurgists have discovered a process of making any article of any lhetal stainless by the deposit of a. film 6f chroiiiiunf by the same method as that employed in the electro-deposi-tion of silver,'known as clectro-plate. It is thus possible to make a knife pf ordinary steel stainless without the employment of stainless steel, a somewhat expensive form of steel, because of the employment of chromium and other alloys in the actual process of the steelmaking. Less chromium is used in the new process. Chromium is deai- as alloys go, It is about 4s fid per pound.' It remains to be seen*, says the Sheffield correspondent of the “Manchester Guardian, ’ ’ whether in practice the results obtained in' experiment are fully confirmed. If they are confirmed, many trades which produce domestic and other ware and bright , parts for motor-car and other fittings will be called upon to adopts the new laboursrtving invention. This is the fourth invention of the kind to the credit of Sheffield metallurgists. Stainless steel and stainless iron we're discovered in Sheffield, and mOre recently' the new nickel alloy which combines with hardness and durability the quality of stain-resist-ing, although not really stainless if subjected to severe tests. The electro.chrome process is of greater significance because it can be applied to all metals. Experience has shown that articles which lighten the load in the kjtchcn and scullery have a very good sale. Stainless "steel table knives, which were produced just before the outbreak of war have been sold in thousands for use in England and the colonies. The invention gave the Sheffield cutlery trades a new lease of life. Factories arc all busy now on the production of stainless cutlery.
