The 303 stainless steel can be machined more easily than 304 stainless steel by adding a small amount of sulfur and phosphorus.304 vs 316 Stainless Steel | Metal Casting BlogThe two most common stainless steel grades are 304 and 316. The key difference is the addition of molybdenum, an alloy which drastically enhances corrosion resistance, especially for more saline or chloride-exposed environments. 316 stainless steel contains molybdenum, but 304 doesnt.
Its resistance to general corrosion is similar to that of 440C stainless steel, but it has much greater fracture toughness. S53 steel is double vacuum melted (i.e., vacuum induction melted and then vacuum arc remelted or "VIM/VAR") for high purity, leading to much greater fatigue strength.Effect of pH on corrosion behavior of 316L stainless steel high corrosion resistance stainless steelNov 27, 2017 · The effect of pH on the corrosion behavior of 316L stainless steel (SS) was investigated.
