Stainless Steel – It's English Discovery 1912

I thought as Stainless Steel was discovered here in England, by Harry Brearley, I thought it would be interesting write It's history. Brearley was born in Sheffield, England in 1871. His life had humble beginnings as the son of a steel melter. He left school at the age of twelve to enter his first employment as a labourer in one of the city's steelworks, being transferred soon afterwards to the post of general assistant in the company's chemical laboratory.

For several years, in addition to his laboratory work, he studied at home and later in formal evening classes, to specialize in steel production techniques and associated chemical analysis methods.

By his early thirties, Brearley had earned a reputation as an experienced professional and for being very astute in the resolution of practical, industrial, metallurgical problems. It was in 1908, when two of Sheffield's principal steel making companies innovatively agreed to jointly finance a common research laboratory (Brown Firth Laboratories) that Harry Brearley was asked to lead the project.

In 1912, Harry Brearley of the Brown-Firth research laboratory in Sheffield, England while seeking a corrosion-resistant alloy for gun barrels, discovered and subsequently industrialized a martensitic stainless steel alloy. The metal was later marketed under the "Staybrite" brand by Firth Vickers in England and was used for the new entrance canopy for the Savoy Hotel in London in 1929.

Brearley died in 1948, at Torquay, a coastal resort town in Devon, south west England. He is buried at Sheffield Cathedral.

It was probably Harry Brearley's upbringing in Sheffield, a city famous for the manufacture of cutler since the 16th century, which led him to appreciate the potential of these new steels for applications not only in high temperature service, as originally envisioned, but also in the mass production of food-related applications such as cutlery, saucepans and processing equipment etc. Up to that time carbon steel knives were prone to unhygienic rusting if they were not frequently polished and only expensive sterling silver or EPNS cutlery was generally available to avoid such problems. With this in mind Brearley extended his examinations to include tests with food acids such as vinegar and lemon juice, with very promising results.

Brearley initially called the new alloy "rustless steel"; the more euphoric "stainless steel" was suggested by Ernest Stuart of R.F. Mosley's, a local cutlery 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 local cutlery 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 left the 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.

The Chinese call Britain 'The Island of Hero's' which I think sums up what we British are all about. We British are inquisitive and competitive and are always looking over the horizon to the next adventure and discovery.

Stuart $18.95 Stuart Shorter was an unkempt, violent, paranoid, knife-wielding, homeless maniac. He was also witty, imaginative, intelligent, and charming. When Alexander Masters finished a first draft of a biography of the fascinating vagrant, Shorter rejected it as being "boring," and told him to rewrite it as a murder mystery to discover who "murdered" the boy he had been. Masters took Shorter`s advice, and rewrote the book in reverse chronology, leaving the initial traumas that derailed Shorter`s life for the final chapters. The result is an eerie and unforgettable mini-masterpiece: the reader witnesses Shorter move backwards in time from his current squalor through a series of devastating experiences until he is finally restored as a cheerful and curious young boy.
