Type 416

Stainless Steel

416 Stainless Steel

Type 416 stainless is a martensitic steel alloy with added sulphur - this gives the alloy excellent machining properties, infact, they are best of any stainless steel.

Non-Galling Capabilities

The added sulphur also improves non-galling characteristics. However, this performance comes at a cost. Corrosion resistance is limited, as is formability and weldability is poor. Corrosion resistance is at its optimum performance if the alloy is hardened and tempered. Because of their high machinability and low cost of the alloy, Type 416 steels are available in highly tempered, hardened or unhardened forms.


Type 416 stainless steel has the best machining capabilities of any stainless steel, thanks to the introduction of sulphur as a core element. However, such performance is negated in terms of reduced corrosion resistance, formability and weldability.

Typical Applications

Commercial applications for this engineering material include:

  • Automotive components
  • General engineering
  • Washing machine parts
  • Motor shafts
  • Gears
  • Valves & pumps

We stock Type 416 in flats, round bar, square bar and hexagon bar.
