Stainless Steels
Stainless steels are selected in accordance with their corrosion resistance. They have been used for almost more than 100 years cause of their durability, appearance, and cleanability. These things can be found in your home, prestigious buildings, transport, food, and beverage handling, chemical plant, and medical equipment.
Chromium is one of the essential elements of stainless steel, which makes it has stainless characteristics, but most commonly the used grade is type 304, containing 8% nickel. Furthermore, it is one of a family of grades known as “austenitic”. They are featured with good ductility as well as ease of forming and welding. Because it is maintained at very low temperatures, so they can be selected for cryogenic applications. While some grades retain their properties to high temperatures as well.
Nickel is an important alloying element in all the commercial grades of the duplex stainless steel family. These have higher strength than the common austenitic grades but cannot be used over such a wide temperature range. Nevertheless, they are finding increasing use in structural applications where strength is important.
Some grades within the other families of stainless steels - ferritic, martensitic, and precipitation hardening - do contain a small percentage of nickel which enhances their properties.
Stainless steel is the largest single first use of nickel, accounting for 60.9% of nickel production in 2009. In the same period, 58.3% of the stainless steel was melted with chromium-nickel austenitic grades.
