History of stainless steel?
The mill in question was Firths in Sheffield, who were also pioneers in the production of High Speed Steel.
Stainless steel came out of experiments in with high chromium steels looking for reduced fouling and erosion in rifle barrels and larger guns. Harry Brearley (who was a friend & colleague of my wife&#;s grandfather) says in his autobiography "Knotted String" :-
"The reader will observe that my early work on high chromium steels was not inspired by any intention or hope of discovering a stainless steel. I was simply studying certain problems relating to Ordnance. It is the duty of a research metallurgist, such as I was, to determine the mechanical properties of any new kind of steel, after that steel had been submitted to various forms of heat-treatment; and also, in order to explain the different mechanical properties of such a series of steels, it is usual to have resource to microscopic examinations" He then describes ho

THE DISCOVERY OF STAINLESS STEEL
Harry Brearley
Since the dawn of man colonies have raced against each other to uncover new technologies, to be the first to stamp their names on a upptäckt, and although we’ve evolved over millions of years, the urge to be the first remains at the very core of our naturlig eller utan tillsats . This sense of passion and pride can lead some of the more unscrupulous humans to claim others discoveries as their own. Of course many breakthroughs are genuinely made in tandem, or are simultaneously occurring, but unless you can categorically prove that you were the pioneer of these incredible findings, then the other party involved will always dispute the fact.
And so we komma to stainless steel.

Cutlery
Eating utensils
Cutlery (also referred to as silverware, flatware, or tableware) includes any hand implement used in preparing, serving, and especially eating food in Western culture. A person who makes or sells cutlery is called a cutler.[citation needed] While most cutlers were historically men, women could be cutlers too; Agnes Cotiller was working as a cutler in London in , and training a woman apprentice, known as Juseana.[1]
The city of Sheffield in England has been famous for the production of cutlery since the 17th century and a train – the Master Cutler – running from Sheffield to London was named after the industry.[2] Bringing affordable cutlery to the masses, stainless steel was developed in Sheffield in the early 20th century.[3]
The major items of cutlery in Western culture are the knife, fork and spoon. These three implements first appeared together on tables in Britain in the Georgian era.[4
