Why is 316 Stainless Steel used on SmartPlug products and not the commonly used 304 Stainless Steel? It’s simple – it’s the best choice for our products and here’s why: It’s more heat resistant with the molybdenum element in the 316 Stainless Steel option, helping resist corrosion to chlorides such saltwater and de-icing salts.
The components of 316 and 304 Stainless Steel Compared – 304 contains 18% chromium and 8% nickel while 316 contains 16% chromium, 10% nickel, and 2% molybdenum.
Because our products are used in the outdoors, they must be safeguarded from weather elements and unnecessary damage from corrosion, which in turn increases the product’s lifespan.
