PMET 270

Details

Characteristics and Composition

PMET 270 is a cored wire specifically designed for arc spray systems. It produces a partially amorphous, hard, abrasive and corrosion resistant coating, with a service environment up to 1600 degrees F. High chrome like finishes can be obtained by typical grinding and lapping techniques. PMET 270 has found use in a wide variety of high wear applications, anti-skid surfacing applications, and corrosive environments. The addition of 9% nickel gives it greater corrosion resistance than PMET 273 for most environments.
