416 stainless steel sheet

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.
Product Information
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. Although Alloy 416 and other martensitic stainless steels are not as resistant as austenitic or ferritic stainless, it still demonstrates good corrosion and oxidation resistance plus high strength in the hardened and tempered condition. Alloy 416HT is easily machined, is always magnetic, and has low frictional properties that reduce galling and seizing.

Resistance

Resistant to food/water produce, and atmospheric conditions. While 416 stainless steels are not ideal for sulfuric chemical environments such as oceanic settings. Resistant to heat below its treatment temperature.

 

Processing

Commonly heat-treated at ~1400°F. This grade can be treated to achieve different mechanical properties, but it lacks high corrosion resistance. The ability to heat treat the grade allows it to be viable in many applications. Our 416 stainless steel can come in two conditions including condition Annealed and condition T.

 

Applications

  • Pump Shafts
  • Bolts
  • Valves
  • Screws
  • Gears
  • Fasteners
  • Studs
  • Motor Shafts

Benefits

  • Corrosion resistance to natural food acids, natural waters, and waste products
  • Known for being the free machining grade
  • Its hardenability allows it to be used in various applications
  • Fair resistance to sealing at mild temperatures
