Available 321 Stainless Steel Tube Erw Vse Fw Polish Fluid Transport Purpose
1. Introduction
The 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.
