416 Stainless Steel Bar

UNS S41600

Stainless steel 416, also known as UNS S41600 is a martensitic grade of stainless steel. Martensitic stainless steels were designed as a type of alloy that could be hardened through heat treatment and would also be corrosion resistant, although not as corrosion resistant as austenitic or ferritic stainless steels. Stainless Steel 416 is magnetic, highly machinable and is known for being wear resistant. Other characteristics include: non-seizing and non-galling properties, resistance to mildly corrosive environments, and reasonable strength in the tempered and hardened state. Usually ordered in the A (annealed), T (intermediate temper) or H (hard temper) conditions. Stainless Steel 416 is not approved for use in high sulfur environments (NACE MR-01-75, MR-01-03). Generally considered to be the first “free machining” stainless, Stainless Steel 416 can be easily turned, tapped, broached, drilled, reamed, threaded and milled per various machine manufacturer’s recommendations for various suitable tool speeds, feeds and types.
