POSTALLOY® PS-40 is a non-cracking hardfacing alloy excellent for use on cutting edges. The micro structure of PS 40 consists of a tough tool steel matrix with hard, tightly packed micro-constituents for added wear resistance. The alloy properties create a crack-free fracture resistant cutting edge even under high heat conditions created by extreme friction.
