316 stainless steel is a relatively new grade of stainless steel and just recently begun to see widespread usage. It’s strength, durability, and relative resistance to corrosion make it ideal to be used in a broad selection of applications. The main distinction is the addition of manganese, an alloy that greatly improves corrosion resistance, particularly for sodium or chloride-exposed places. 316 stainless steel also contains manganese, which improves wear resistance as well which makes it great for making magnetic balls.
The magnetic balls used in making the two ranges of stainless steel have their benefits and disadvantages. While they are both exceptionally tough and extremely corrosive resistant, they are not identical. Although both are very tough, the higher ratio of alloy to iron leaves 316 stainless considerably more powerful than its less expensive counterpart. Less corrosion resistance implies it’s more susceptible to damage from things such as salt spray and oil trickle. Both grades of stainless are nevertheless more wear resistant compared to lower tier, which might be important depending on the place you intend to utilize it.
For areas where you will need an extremely tough, long-lasting material that does not corrode, you should consider using either of the two. For general use, the superior hardness of the high grade of stainless steels outweighs the slightly lower corrosion resistance of the lower quality. However, if you’re trying to find a product with maximum corrosion resistance, you should choose the higher-grade magnetic balls. There’s a tradeoff between durability and price, and in most cases you’ll pay more for the higher quality.
