Type 416 stainless is martensitic, hardenable chromium steel. One of the first free-machining stainless steels ever developed, 416 offers considerable flexibility in machining applications. The addition of manganese-rich sulfides evenly distributed throughout the steel provides a natural lubricant, preventing build-up on cutting tools during the machining process.  The additives also act as chip breakers, substantially increasing machining rates to 85%.  Free machining steel like 416 allows for faster speeds and feeds and an overall increase in cutting tool life.

One of the most common alloys to undergo heat treating, 416 SS is capable of attaining the highest strength, hardness and wear resistance of all stainless alloys.  It also has excellent machinability and non-galling characteristics.  416 stainless steel is often used in parts that require extensive machining and corrosion resistance. Heat treating 416 makes it an ideal selection for cutting tools.  We are suppliers of 416 stainless steel plate in 0.1875" to 4.000" thickness.

About Heat Treating 416

The crystalline structure of stainless steel can be altered when the material is brought to an extremely high temperature, then cooled at a specific rate.  AISI 416 is one of the most common alloys to undergo this process to permanently alter its physical condition.  The benefit of heat treating stainless grades of 410 or above is the ultimate increase in the material hardness.  Cutting tools, for example, made from material that has been heat treated, is strong enough to resist breaking or warping during use.  To harden 416, the metal must be heated to a minimum of 1400°F followed by quenching and cooling. Tempering is often a final step to reduce brittleness.
