RUSTLESS IRON.

FITTINGS THAT WILL NOT TARNISH. The progress that is being made at Shsffield in reducing the cost of stain-* less iron, for which a great future is prophesied, is described in tlhe Sheffield Chamber of Commerce journal. Experiments have been in hand for some time, it is stated, to find whether a ductible (malleable) material could be made with rust-resisting properties, so that it could be used for many purposes for which stainless steel, op account of its hard nature, has proved, unsuitable. Stainless steel cannot be used for articles of intricate shapes with sharp angles, which have to be fashioned out of the cold metal. Stainless steel also requires to be hardened to ensure production and retention of its rustless properties, and many articles are so shaped as to make hardening an impossibility. Rustless iron overcomes all these difficulties, and is a remarkable advance on anything previously offered. This material may possibly revolutionise many trades where the use or ordinary iron or, steel has so far been unsuitable ’owing to the inability of; ordinary iron or steel to withstand corrosive action. Rustless iron, only requires to be finished bright and with a good polish to be rust-resist-ing. All the user has to do is to polish the surface. POSSIBLE USES. Rustless iron will take a polish equal to that obtained on electroplate, apd is impervious without attention to rust and tarnishing. This cannot be said of brass, copper, elec-tro-plate, or even silver, all of -which, unless regularly cleaned, tarnish. Rustless iron lias been put tp the most severe tests. A few of its pos-

1 sible uses are for. motor-car fittings, bodies, wheel, discs, door-handles and brackets, drawer handles, cooking utensils, name-plates, wire door mats, golf clubs, and fireplace apd hearth furniture. FLEXIBLE STEEL. MAKING CUTLERY CHEAPER AND BETTER. One of the most, promising results yielded by further experiments at Sheffield into tfiiie possibilities pf| an improved stainless steel is the production of a material, the flexibility of which is so great. tJhat in tables knife form it can be bent almost double without cracking. This flexibility is in contrast with the brittleness which has been one of the chief causes of the high, cost pf manufacturing stainless cutlery. It also reduces the wastage by something like 10 to 20 per cent.'
