In layman's terms, stainless steel is steel that not easy to rust, actually some stainless steel both has rustless property and has acid resistance (corrosion resistance) property. Harry Brearley, a well-known metallurgical scientists graduated from the University of Sheffield in the early 20th century, invented the stainless steel. The invention and use of stainless steel can be traced back to the First World War. British scientists cloth Henry Bradley Hurley is authorized by the British government military armory to research and improve the work of weapons manufacturing. At that time, the rifle barrel of the soldiers’ is easy to wear, Bradley Hurley wanted to invent a scratch-resistant alloy steel. The stainless steel invented by Bradley Hurley got the patent of the United Kingdom in 1916 and begin the stainless steel fabrication from then on. Ever since then, the accidental discovery of stainless steel from the rubbish pipe swept over the world, and Henry Bray is also known as the "father of the stainless steel.
Classification of Stainless Steel
According to different organizational structures at room temperature, stainless steel can be divided into martensitic stainless steel, austenitic stainless steel, ferritic and duplex stainless steels; According to major chemical composition, it can be divided into chromium stainless steel and chrome-nickel stainless steel; According to different purposes, there are nitric acid-resistant stainless steel, resistant to sulfuric acid stainless steel, seawater-resistant stainless steel; According to corrosion types of points it can be divided into the resistance to pitting corrosion stainless steel, stress corrosion resistance stainless steel, the resistance to intergranular corrosion stainless steel; According to different functional characteristics, it can be divided into magnetic stainless steel, free cutting steel, low-temperature stainless steel, high strength stainless steel. Because stainless steel has a series of characteristics of excellent corrosion resistance, formability, compatibility, as well as strength and toughness in a wide temperature range, so it is widely used in heavy industry, light industry, daily industry as well as architectural decoration industry.
Typical Use of Stainless Steel
First , most of the stainless steels are used in buildings which requires to maintain the original appearance of the building in a long time. When determining the type of stainless steel, the main consideration is the required standards of beauty and the local atmospheric corrosion. However, a growing number of other applications is just to seek the structural integrity of impermeability. For example, the roof and side walls of industrial buildings. Second, the facade decoration function,stainless steel plates can be widely used in the facade of shop fitting, large format stainless steel can even be printed personalized patterns, the process is called UV, which is a process popular in recent years.
