Free Machining Stainless Steel Alloys

These alloys often allow for machining quality for micro components that is predictable and management resulting in high quality parts with a quick turnaround.

Free machining stainless steel alloys.

The addition of these elements is in the region of 0 15 0 35. The free machining variation of type 410 is type 416 and for type 420 the specifier should consider type 420f. Free machining stainless steels grades introduction. Free machining steel with lead also allow for higher machining rates.

This increases the machinability of the material by breaking the chips into small pieces thus avoiding entanglement in the machinery. Table 1 compares common grades of free machining stainless steel grades. 416 stainless steel is a free machining martensitic stainless steel with 12 13 chromium that can be hardened by heat treatment to higher strength and hardness levels. This enables automatic equipment to run without human interaction.

For instance one of the most commonly used free machining steel grades is 12l14 bar. The traditional free machining stainless steel grades have been based on sulphur s additions in the uk or alternatively selenium se additions which have been favoured in the united states. Steel that breaks into small chips in cutting operations resulting in an increase in machinability a superior surface finish and long tool life. Free machining alloys when machining precision parts free machining materials often yield the fastest speeds and lowest cost to the end user.
