history of stainless steel

 

 

  As per documentations regarding the history of stainless steel, Harry Brearley of England invented stainless steel. It is believed that his interest in steel was initiated as a result of his father’s profession, which was melting steel. Brearley put in efforts night and day to become an expert in the analysis of steel and its production. In 1908, he set up the Brown Firth Laboratories. Four years later in 1912 he was asked to help solve the problems encountered by a small arms manufacturer. It was then that his search for a better type of steel began. He realized that the best type of all-purpose steel would be one with better resistance to erosion, and not corrosion.

In the initial stages Brearley began his experimentation with steels containing chromium. This is because this form of steel was known to melt at a higher temperature in comparison to other metals. As per the recorded history of stainless steel the first authentic stainless steel was melted on 13th August 1913. This is said to have contained 0.24% carbon and 12.8% chromium.

After this initial invention, years later, more precisely, by the late 1920’s, two additional kinds of stainless steel were found. These were the martensitic stainless with 13% to 18% chromium contend, austenitic stainless steel that contained 18% chromium and 8% nickel. Both these variations turned out to be very versatile and useful. Over the years, a group of steels containing a minimum of 10.5% chromium came to be regarded as stainless steel. This group of metal is distinguished from other metals as it creates a protective film of chromium oxide that renews itself thus preventing any form of rusting.

As the history of stainless steel goes, right from its invention in 1912 till date, there is constant study an upgrade of this metal. Newer grades keep coming about. This leads to the metals increased used in households and in the industries. Because of its strength, high melting point, versatility, corrosion and erosion resistance, aesthetic appearance, it is put to multi-purposes uses at home, such as stainless steel sinks, cupboards, utensils, cookware, etc. ~ author Karishma Bajaj.
