Brearley initially called the new alloy "rustless steel"; the more euphoric "stainless steel" was suggested by Ernest Stuart of R.F. Mosley's, a localcutlery manufacturer, and eventually prevailed. It is reported that the first true stainless steel, a 0.24wt% C, 12.8wt% Cr ferrous alloy, was produced by Brearley in an electric furnace on August 13, 1913.

The well told story is that Brearley noticed in his sample bin one of his pieces which had not shown signs of rusting after being exposed to air and water. This was further examined and analysed, a new steel, which he called "rustless steel", was born, the first commercial cast coming from the furnaces in 1913. Its name was changed to the more euphonic "Stainless Steel" following a suggestion from Ernest Stuart of R.F. Moseley's, a localcutlery maker, and this eventually prevailed.

He was subsequently awarded the iron and steel institutes's Bessemer Gold Medal in 1920.

Virtually all research projects into the further development of stainless steels were interrupted by the 1914-18 War, but efforts were renewed in the 1920s. Harry Brearley had leftthe Brown Firth Laboratories in 1915, following disagreements regarding patent rights,

The research continued under the direction of his successor, Dr. W.H. Hatfield. It is Hatfield who is credited with the development, in 1924, of a stainless steel which even today is probably the widest-used alloy of this type, the so-called "18/8", which in addition to chromium, includes nickel (Ni) in its composition.

Have you recently purchased a granite counter top for your new home or have you updated and remodeled? If you have you were probably shocked at the prices when you were sent to a plumbing supply center or a kitchen and bath dealer to pick out your stainless steel sink and faucets. The number one rule in selecting a sink is stay away from the hype, and do not over pay for a name brand sink that your neighbors will not recognize. Focus on quality and utility, your kitchen is a work center and your sink should complement your families lifestyle. Do you cook a lot, and wash large pans if so you may want to consider a large single bowl 30 X 18 this sink is the current trend. Once you select the appropriate style sink for your family you need to consider the quality of the sink.

Quality features of an undermount sink are that it must be 18 gauge. There is a lot of hype about 16 gauge sinks right now. The industry standard is 18 and it is more than adequate. The difference between 16 and 18 is minimal, most companies advertising a 16 gauge sink are using a three piece construction (not desirable) and only the deck plate is 16. In these cases you will find the manufacturer cut production costs by having the bowls made in 20 gauge (stay away from a sink like this). You also need to find a sink that has a very good undercoating and is padded. The undercoating is used for condensation control as well as noise reduction.
