Material Notes:
Alloy 416 is a martensitic, free-machining, chromium steel alloy that is generally considered to be the first free-machining stainless steel. It has the highest machinability of any stainless steel at about 85% of that of a free-machining carbon steel. Martensitic stainless steels were designed to be hardenable by heat treatment and also corrosion resistant.
Applications: Electrical motors
,Nuts and bolts
, Pumps
, Valves
, Automatic screw machine parts
, Washing machine components
, Studs
, Gears
Corrosion Resistance: High sulfur, free-machining grades like Alloy 416 are unsuitable for marine or other chloride exposure
