Stainless Steel
Stainless steel is a group of iron alloys that contain a minimum of 11% chromium, an element that inhibits the iron from rusting and also provides heat-resistant properties to the steel. Different types of stainless steel include the elements carbon (from 0.03% to greater than 1.00%), nitrogen, aluminium, silicon, sulfur, titanium, nickel, copper, selenium, niobium, and molybdenum. The specific types of stainless steel are often designated by their AISI three-digit number for example 304 stainless.
Stainless steel can be rolled into sheets, plates, bars, wire, and tubing. Stainless steel is an ideal material for many applications because it has the strength of steel and the corrosion resistance of chromium. It can be used in many applications such as cookware, cutlery, surgical instruments, major appliances, vehicles, construction material in large buildings, industrial, and storage tanks and tankers for chemicals and food products.
Stainless steel is generally divided into four distinct groups:
Austenitic Stainless Steel: This is the most common types of stainless steel. Austenitic stainless steels, in comparison with other types, contain elevated levels of chromium, molybdenum and nickel. It is adaptable and known for its excellent strength and malleability.
Ferritic Stainless Steel: This steel contains anywhere between 10.5% and 30% chromium. Ferritic stainless steels usually have low carbon content no more than 0.1%. Ferritic stainless steels are magnetic and are mainly preferred for their resistance to temperature corrosion and stress deterioration cracking.
Duplex Stainless Steel: This steel combines the austenitic with ferritic, resulting in a metal that is stronger than both. This combination gives the steel a higher strength can which can lead to significant weight reductions. Its resilience to corrosion makes it ideal for use in marine applications.
Martensitic Stainless Steel: This steel is structurally similar to ferritic stainless steel but with an elevated carbon content (up to 1.2%), this allows the steel to be hardened to a significant degree. This steel is especially useful for creating medical tools and surgical instruments.
