416 Project 70®+

UNS #S41600

416 Project 70®+ Stainless is an improved modification of 416, the first free-machining stainless steel, that can achieve 100 to 200% longer tool life, 15% faster machining speeds, and improved finishes. Its low frictional properties minimize scratching and galling in service, possessing better non galling properties than 410. 416 Project 70+ PDB® stainless combines the superior machinability of Project 70+ stainless with improved straightness and half-standard dimensional tolerances. This precision drawn bar has been used successfully in a variety of machining operations including CNC Swiss-type screw machines.
