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 ferrite stainless steels
Feature of 416 /UNS S41600 stainless steel:
Stainless steel 416 /UNS S41600 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 stainless steel 416 bars are ordered in the A (annealed), T (intermediate temper) or H (hard temper) conditions.
