In 1913, Harry Brearley of Sheffield, UK discovered ‘rustless’ steel. Although there had been many prior attempts, Brearley has been credited with inventing the first true stainless steel, which had a 12.8% chromium content. He had added chromium to molten iron to produce a metal that did not rust.

Is Sheffield steel stainless?
Sheffield cutlery-makers are still producing stainless steel utensils in the same workshop where the alloy was first used. Cutlery has been made in Sheffield since the 13th century. Harry Brearley developed what is widely regarded as the first ‘rustless’ or stainless steel there, revolutionising the industry.
Who invented stainless steel alloy?
In the late 1890s, German chemist Hans Goldschmidt developed an aluminothermic (thermite) process for producing carbon-free chromium. Between 1904 and 1911, several researchers, particularly Leon Guillet of France, prepared alloys that would be considered stainless steel today.
Who invented stainless steel in 1913?
Harry Brearley
Rustless Steel
Harry Brearley invented the first true stainless steel in 1913. He added 12.8% chromium to iron, and produced a metal that he found was resistant to both corrosion and rust. Brearley discovered this metal while looking for a solution to the problem of erosion in the gun barrels of the British army.
What city invented stainless steel?
Invention of Stainless Steel
In 1913, Harry Brearley of Sheffield, UK discovered ‘rustless’ steel. Although there had been many prior attempts, Brearley has been credited with inventing the first true stainless steel, which had a 12.8% chromium content.
When was the first stainless steel invented?
13th August 1913
On the 13th August 1913 Brearley created a steel with 12.8% chromium and 0.24% carbon, argued to be the first ever stainless steel.
Who makes stainless steel in the UK?
ABC Stainless Ltd has been acknowledged as one of the UK’s leading specialists in stainless steel fabrication since being established in 1981.
Does UK produce stainless steel?
The UK had an approximate demand of 280,000 tonnes during 2021. The UK produces over 200,000 tonnes of stainless steel at the Outokumpu SMACC plant in Sheffield, alongside other stainless production at Liberty Steels, but most of the UK-produced stainless steel is exported.
What is special about Sheffield steel?
With a proud tradition of steelmaking – the world’s first martensitic stainless steel was invented here more than 100 years ago – Sheffield is home to our steel providers Outokumpu. Billets and blooms are used as stock for rolling wire rod or bar (which we then turn into our components!)
Who invented 316 stainless steel?
Adding titanium to the 18-8, Hatfield is also credited with the invention of 321 stainless. In the earlier years, German scientists, such as the Krupp Research Institues, were the quickest to realize the potential of austentic stainless, inventing 316, among others.
What country is stainless steel from?
The 5 biggest exporters of stainless steel in 2021 are Indonesia, United Kingdom, Sweden, Italy and the United States of America. That powerful cohort generated 87% of exported stainless steel by value.
Who has the patent for stainless steel?
it was Philip Monnartz of Germany, in 1911, who published the first detailed work on the corrosion resistance of stainless steel. The following year, 1912, his fellow Germans, Eduard Maurer and Benno Strauss, were the first to patent austenitic stainless steel of a 21% chromium and 7% nickel combination.
Who invented high quality steel?
Sir Henry Bessemer FRS (19 January 1813 – 15 March 1898) was an English inventor, whose steel-making process would become the most important technique for making steel in the nineteenth century for almost one hundred years from 1856 to 1950.
Who made the first steel tools?
Robert Forester Mushet
The steel largely recognized as being the “first tool steel” was developed by Robert Forester Mushet, a British metallurgist, in 1868 [1].
Who invented stainless steel in ww1?
Harry Brearley
On the 2nd October 1913, the eve of the First World War, a routine report was written in the Brown-Firth Research Laboratory in Sheffield, the benefits of which we are still reaping today. Its author, Harry Brearley, chief metallurgist at Thomas Firth & John Brown Limited, had discovered Stainless Steel.
Which city is famous for stainless steel?
Amazingly, the forge that was built in 1879, where stainless steel was originally produced, is still in daily use. It is an emblem of how old and new practices have come to characterize Sheffield’s skillful community today.
Which country is the largest producer of stainless steel?
China
In 2021, China produced the highest volume of stainless steel slabs across the Asia-Pacific region, in which approximately 30.63 million tons of stainless steel was produced.

Which country invented steel first?
The Chinese of the Warring States period (403–221 BC) had quench-hardened steel, while Chinese of the Han dynasty (202 BC—AD 220) created steel by melting together wrought iron with cast iron, thus producing a carbon-intermediate steel by the 1st century AD.
Does stainless steel ever rust?
Some types of stainless steel are more prone to corrosion than others, depending on the chromium content. The higher the chromium content, the less likely the metal will rust. But, over time and if not maintained correctly, rust can and will develop on stainless steel.
Why stainless steel does not rust?
In summary, stainless steel does not rust because it is sufficiently reactive to protect itself from further attack by forming a passive corrosion product layer. (Other important metals such as titanium and aluminum also rely on passive film formation for their corrosion resistance.)
