History of Stainless steel

The invention and use of stainless steel can be traced back to the First World War. At that time, British guns on the battlefield were always shipped back because the bores were worn out and could not be used. The military production department ordered Brellley to develop high-strength and wear-resistant alloy steel, specifically to solve the problem of gun bore wear. Brellley and his assistants collected various types of steel produced at home and abroad, alloy steels of various properties, conducted performance experiments on various types of machinery, and then selected more suitable steels to make guns. One day, they experimented with an alloy steel containing a large amount of chromium. After the wear test, it was found that this alloy was not wear-resistant, indicating that it could not be used to make guns. So they recorded the experimental results and threw them in the corner. . One day a few months later, an assistant came rushing to Braly with a piece of shiny steel and said, “Sir, this is the alloy steel that Mr. Mullah sent me when I was cleaning out the warehouse. Do you want to experiment and see what special effect it has!” “Okay!” Braly said happily, looking at the shiny and dazzling steel.
The experimental results prove that it is a piece of stainless steel that is not afraid of acid, alkali and salt. This kind of stainless steel was invented by Mullah in Germany in 1912. However, Mullah didn’t know what use this stainless steel had.
Braly thought to himself: “This kind of steel that is not wear-resistant but corrosion-resistant can’t be used to make guns, so can it be used as tableware?” He went ahead and made stainless steel fruit knives, forks, spoons, and fruit plates. and folding knives.
The stainless steel invented by Brellley obtained the British patent in 1916 and began mass production. Since then, the stainless steel accidentally found in the garbage dump has become popular all over the world. Henry Brellley is also known as the “Father of Stainless Steel”.

Stainless steel is a type of steel that contains a minimum of 10.5% chromium content by mass. The addition of chromium creates a protective oxide layer on the surface of the steel, which makes it highly resistant to corrosion and staining.

Stainless steel has a wide range of applications due to its excellent corrosion resistance and durability. It is commonly used in the production of kitchen appliances, cookware, cutlery, medical equipment, automotive parts, construction materials, and many other products.

There are different grades of stainless steel, each with varying properties and composition. The most commonly used grades of stainless steel include 304, 316, and 430. Grade 304 is the most commonly used and is known for its high corrosion resistance, while grade 316 is often used in marine environments due to its superior corrosion resistance. Grade 430, on the other hand, is less corrosion resistant than grades 304 and 316 but is often used for applications that require a lower cost option.

Stainless steel is known for its corrosion resistance, high strength, and durability. It is commonly used in applications that require resistance to moisture, such as in kitchen utensils, appliances, medical equipment, and construction materials. It is also used in the automotive and aerospace industries due to its high strength-to-weight ratio.

Stainless steel comes in various grades and finishes, each with its unique properties and uses. The most common grades of stainless steel are 304, 316, and 430, which vary in their composition and properties. The finish of stainless steel can also vary, with common finishes being brushed, polished, and satin.
