Stainless steel is a group of iron alloys containing at least 11% chromium, an element that inhibits iron from rusting and also provides heat resistance to steel.
Different types of stainless steel include carbon (from 0.03% to greater than 1.00%), nitrogen, aluminum, silicon, sulfur, titanium, nickel, copper, selenium, niobium, and molybdenum.
Specific types of stainless steel are often referred to by their AISI three-digit number, such as 304 stainless steel.

Stainless steel can be rolled into sheets, plates, bars, wires, and tubes.
Stainless steel is an ideal material for many applications because it has the strength of steel and the corrosion resistance of chromium.
It is used in many applications such as cookware, cutlery, surgical instruments (medical bone plates), major appliances, vehicles, construction materials in large buildings, industry, and storage tanks and tank trucks for chemicals and food.
Stainless steel is generally classified into four different groups:
Austenitic Stainless Steel: This is the most common type of stainless steel.
Austenitic stainless steel has higher levels of chromium, molybdenum, and nickel than other types of stainless steel.
It is highly adaptable and known for its excellent strength and ductility.
Ferritic Stainless Steel: This steel contains between 10.5% and 30% chromium.
Ferritic stainless steels typically have low carbon contents of no more than 0.1%.
Ferritic stainless steels are magnetic and are primarily preferred for their resistance to temperature, corrosion, and stress-deterioration cracking.
Duplex Stainless Steel: This steel combines austenite and ferrite to create a metal that is stronger than either alone.
This combination gives the steel greater strength, which can result in significant weight savings.
Its corrosion resistance makes it ideal for use in marine applications.
Martensitic Stainless Steel: This steel is similar in structure to ferritic stainless steel, but has a higher carbon content (up to 1.2%), which allows the steel to be hardened to a great extent.
This steel is particularly suitable for making medical tools and surgical instruments.
