Type of Stainless Steel(Part One)
Now if you are wondering what if that thin chromium film or coating gets damaged, it repairs itself as long as it reacts with oxygen. Although we are emphasizing on a well-known and much boasted property of stainless steel, we must not ignore the fact that even this alloy can corrode, if it doesn't get enough oxygen to react and form that layer that protects it from corroding and rusting. This could happen with storing of foods in a stainless steel container for a prolonged time, as it prevents the contact from oxygen and results in corrosion. Some of the other common elements that are used in making this alloy include nickel, molybdenum and nitrogen.
Properties and Types of Stainless SteelThere are mainly five types of this metal alloy and more of it has been discussed below.
Austenitic Stainless Steel
This is the most commonly used type and is derived with a mix of nickel, nitrogen and manganese. It is also known for its flexibility that is achieved with the use of at least 7% of nickel content. The properties of stainless steel can further be modified with the addition of elements such as titanium, copper and molybdenum. The structure makes it more suitable for welding etc and can be used to make kitchen sinks, food processing equipment, doors and windows, for roofing, in ovens and making chemical tanks, etc.
