harry brearley – the man of steel - stainless steel ice balls
Have you ever used stainless steel?
An iron alloy with at least 10
5% chromium also contains different amounts of carbon, silicon and manganese.
With a wide range of applications, at home you will definitely see it in the sink and in the cutlery you use.
Although it can be defined in such a simple way, the story of stainless steel began as early as the 1820 s.
It took nearly a century to perfect and highlight its use.
In the 1820 s, researchers from Britain and France began to learn
Chromium is resistant to some acid.
In the subsequent hundred-year study, many people created, described and explained what we now call stainless steel.
But it is widely believed that the person who found it was Harry brary. Was it a sign?
Brearley was born in 1871 and was born in a poor family.
Brearley was born in a family based in Sheffield, calling it fate, or fate.
Sheffield's steel production accounts for more than half of European steel production, accounting for more than British steel production, and is undoubtedly the world's steel capital.
However, Bradley knows nothing about what he will be.
He dropped out of school at the age of 11 and started working.
He has moved a lot of jobs either because he doesn't like them or because of labor regulations.
He was then hired as a bottle washer by James Taylor, the lab's chief chemist.
Noting Brearley's curiosity, Taylor first taught him arithmetic and algebra and then went on to teach him everything he knew-from painting and welding to binding books and metal processing. Brearley hero-
Worship Taylor, worship him.
After Taylor moved to Australia, Bradley was promoted to a lab assistant and continued to enjoy his work.
He reads all the things he can come into contact with about metallurgy and is trying when he doesn't read or work.
Stole his heart, he did a lot of work on steel, he went to the place where steel took him.
This made him move to Russia in 1903 and did not return to the UK until 1907.
He then went on to work on a project for a weapon manufacturer and started to study the erosion of the rifle barrel.
To solve this problem, he spent the second year making crucble furnace steel with different contents of chromium.
He went to the electric stove in August 13, 1913.
Although his first lineup is not good, the second one is only 12. 8% chromium, 0. 24% carbon, 0.
44% manganese and 0.
The result is that 2% of silicon is better.
Interestingly, while it doesn't solve the problem at hand, Brearley can't help but notice that this sample metal has interesting properties.
It etched very slowly and performed better than carbon steel in rust.
It is resistant to nitric acid and performs the same as vinegar and lemon juice.
He showed it to the tableware manager Ernest Stewart, who was the first to call it stainless steel.
However, the months after this discovery are not easy.
Brearley's stainless steel was not immediately appreciated, and when it was finally seen, there were others who wanted to take credit from Brearley.
But again, it was Brisley who realized the potential of the role he played, and hundreds of years later we were still discussing the issue, not what those who tried to steal the steel reputation brought to him.
