Stainless Steel: Properties and Characteristics
Stainless steel, on the other hand, stands as a testament to modern metallurgy. Its remarkable properties make it an essential material in a vast array of applications, from the medical field to aerospace. Understanding its characteristics is crucial to successfully Cerakoting it.
Stainless steel is, in essence, an alloy of steel and chromium. The addition of chromium, typically at a concentration of at least 10.5%, is what gives stainless steel its remarkable corrosion resistance. This chromium reacts with oxygen in the atmosphere to form a passive layer of chromium oxide on the surface. This layer is incredibly thin, but it acts as a barrier, protecting the underlying steel from rust and other forms of corrosion.
Various grades of stainless steel exist, each with unique properties tailored to specific applications. The most common grades include 304, 316, and 416. 304 is a general-purpose grade known for its good corrosion resistance and weldability, making it a versatile choice. 316 adds molybdenum, enhancing its resistance to chlorides and other corrosive substances, making it ideal for marine and chemical applications. 416 is a free-machining grade, meaning it’s easier to machine but may have slightly lower corrosion resistance than other grades. The grade of stainless steel will impact the final result of Cerakoting it.
Key Properties
The defining properties of stainless steel are key to consider when applying a Cerakote finish.
Corrosion Resistance: As mentioned earlier, stainless steel is already highly resistant to corrosion. Cerakote further enhances this protection, especially in environments where the steel may be exposed to harsh chemicals or prolonged moisture.
Hardness: Stainless steel is generally quite hard, making it resistant to scratches and dents. This hardness contributes to the overall durability of the finished product when combined with Cerakote.
