Molybdenum & Stainless Steel
The name for the chemical element molybdenum evolved from the ancient Greek word for lead, as it was often confused with lead ores. It is not found alone as metal but occurs as an oxide in various minerals. Silvery-gray in appearance, it has one of the highest melting points of any element. Because of this property, it provides incredible strength and stability to steel alloys, which is why its most common use involves steel production. All of the 300-series grades of stainless steel contain some molybdenum, with certain grades that are highly resistant to corrosion containing up to 7 percent molybdenum. However, these higher grades are only necessary for use in extreme environments where metals are exposed to extremely high chloride levels.
Comparison between 304 VS 316 Stainless Steel
When looking at these two steel grades, both look similar in appearance and have comparable chemical compositions. Both resist rusting and corrosion well, while also offering added durability. When comparing 304 vs. 316 stainless steel, the latter’s higher cost can be attributed to its better corrosion resistance. Because of this price differential and the limited environments in which 316 steel is advantageous, the 304 grade is the most widely used austenitic stainless steel.
