Producing Different Types of Stainless Steel
When producing stainless steel, several different materials can be used to achieve different results. These include:
Carbon
Stainless steel with high carbon content is much more durable and longer-lasting than other alloys. This type of stainless steel is popular for the production of food-grade utensils and cooking implements.
Chromium
Stainless steel made with chromium is much more resistant to corrosion, stains, and tarnishing. One well-known example of this type of stainless in use is the Gateway Arch in St. Louis.
Nickel
Making stainless steel with nickel improves the formability, weldability, and ductility of the material. This also improves its corrosion-resistant properties. Nickel is what allows for stainless steel to be such a versatile alloy.
The Three Primary Types of Stainless Steel
While there are thousands of different types of stainless steel alloy that can be produced, most alloys will fall into one of the following three categories:Austenitic stainless steel,Ferritic Stainless Steel,Martensitic Stainless Steel.
