Steel is an iron alloy which has improved chemical and physical properties. The steels most commonly found are alloyed with between 0.2% and 2.15% carbon, but it is possible to find some steels that are alloyed with other materials such as tungsten, chromium, vanadium and manganese. Steel has been used since ancient times, but until the mid19th century, when the Bessemer process was invented, it was inefficiently and expensively produced.
Plate VS Sheet
Any metal that is thicker than a foil and thinner than 6 mm, the width of a metal plate, is sheet metal. For building structures which do not need longevity, sheet metal is sometimes used. Often, for extra strength without increasing weight, it is often corrugated or diamonded. Corrugation is the creasing of the metal to create ridges at periodic intervals, and diamond is the addition of diamond ridges that add structure to the metal.
A Plate is any sheet of metal having a thickness of 6 mm or more. In applications where longevity is more important than saving weight, plate metal is used. It is used to pass crash tests in cars where durability is required.
The gauge (thickness) of the metal is the only distinction between sheet and plate steel. Depending on the differing durability and weight specifications for various projects, they both have very distinct applications.
For general stainless steel applications such as kitchen and food processing applications, liquid storage and tanks, heat exchangers, building facades, pressure vessels and other applications involving fresh water environments, the 304 Stainless Steel Sheet is a great choice.
Stainless Steel Sheets 430 is the representative of ferritic stainless steel, with low coefficient of thermal expansion, excellent resistance to oxidation, SS sheets 430 & 420. These sheets have a special ability to resist nitric acid attacks that open their doors to specific chemical processes for application. The SS 430 sheets are ductile in the annealed state, and do not harden excessively during cold work. Using a wide range of roll forming or mild stretch-bending operations, as well as the more common processes of drawing and bending, they can be formed.
What does SS 316L sheet mean?
SS 316L sheet is a highly corrosion resistant type of stainless steel as the high concentrations of nickel and molybdenum properties help prevent corrosion from cracking and pitting. 316L stainless steel is very durable and resistant to acidic solutions such as bromides, sulfuric acid and chlorides and to chemical pollutants.
The SS 321 sheet is stabilised stainless steel with various advantages and excellent resistance to corrosion. 321 grade is stabilised against the formation of chromium carbide. It is used to produce different items for extended service at temperatures between 800 degrees F and 1500 degrees F. Owing to its excellent mechanical properties, it is also considered best for high-temperature facilities.
