| *nominal |
In salt spray testing, the corrosion resistance of AMETEK's Plus P/M alloys is significantly greater than that of its other P/M products.
Additionally, in closed-jar tests in aqueous solutions of 10% sulfuric acid and 20% sulfuric acid, 316L Plus experienced no weight change during a 400-hour period, further exemplifying its corrosion resistance.
Green Properties
Green properties for standard 316L and 316L Plus, lubricated with 1% lithium stearate, were determined per MPIF Standard 15. As you can see in the graphs below, the Plus material has improved compressability with a slight decrement in green strength.
