High
Phosphorous
High
phosphorous ENP also offers maximum corrosion resistance to strongly acidic corrosive
environments like oil, drilling, coal mining and pickling.
High phosphorous
is the most popular ENP choice because steel parts often perform like stainless
steel.
EN
does not build up on edges or ends, providing a uniform 100% part thickness and
coverage. Micro Plating ENP may allow for substitution of less expensive materials
in place of stainless steel alloys or hard-to-machine substrates. Salt spray tests
per ASTM B117 repeatedly show that high phosphorous ENP outperforms other EN coatings
with 9% or less phosphorous by over 4 to 1.
