Stainless Steel Computers Part 1: The Main Choice for the Food Industry. In this first part of the article, we are going to talk about the Stainless Steel main characteristics and family differences.
Stainless Steel History
Despite the fact that iron has been used for thousands of years playing a crucial role in society's development, the process of making steel from it was only discovered 150 years ago. The 19th century marks the finding of chromium-alloyed steels with incredible resistance to corrosion. But was only at the beginning of the 20th century that this incredible material was patented and industrially manufactured. "While seeking a corrosion-resistant alloy for gun barrels in 1912, Harry Brearley of the Brown-Firth research laboratory in Sheffield, England, discovered and subsequently industrialized a martensitic stainless steel alloy, today known as AISI Type 420. The discovery was announced two years later in a January 1915 newspaper article in The New York Times."[2] |

Stainless Steel PropertiesPart of the alloy family, Stainless Steel contains 10% to 30% chromium which provides this incredible metal a remarkable resistance to corrosion and rust. These properties comes from the fact that the chromium forms a layer of chromium oxide on the surface of the metal preventing oxygen from coming into contact with the iron and corroding it. As the oxygen in the atmosphere reacts with the iron in carbon steel, "iron-oxides" are created, which appear as "red rust" on steel. Steel corrosion produces a layer of oxide several times thicker than the original iron present, often resulting in the surface flaking or rusting and reducing the thickness of the steel.
Comparable to glass, stainless steel is nonporous, so it does not absorb dirt and grime like other materials. This makes it easier to clean and keeps any bacteria or germs from getting trapped on the surface, also protecting internal circuits from being harmed by mold and other contaminants. |
Stainless Steel FamilyDifferent types of stainless steel can be distinguished based on their chemical compositions as well as their technical characteristics:
Due to its corrosion-resistant properties and the ability to withstand harsh conditions, Stainless Steel is heavily used in the food and maritime industries. For that reason, it makes sense to choose an industrial-grade computer made of the same material widely used in the industry. As one of the leading industrial-grade PC producers in Australasia manufacturing Stainless Steel computers for over two decades, STX Technology is the first choice when looking for rugged computers. You can find below some of our top-selling Waterproof Stainless Steel Computers.
In the next post, we will cover why we use the Austenitic Stainless Steel family in our products, specifically the 304 and 316 grades. We will discuss the advantages of using this type of steel and why it is the best choice for manufacturing Touch Computers for Industrial & Harsh Environments.
