About 416 stainless steel
Grade 416 steel is a free-machining stainless steel with a machinability of 85%, highest of all stainless steels. With most of the free-machining stainless steels, the machinability can be improved by adding sulphur, which leads to the formation of manganese sulphide inclusions. Addition of sulphur also reduces the formability, weldability and corrosion resistance of 416 steels to below that of grade 410. Because of their high machinability and low cost, grade 416 steels are available in highly tempered, hardened or unhardened forms.
Martensitic steels with high hardness are manufactured using methods that require final hardening and tempering treatments. The corrosion resistance of these steels is lower than that of austenitic steels. Decrease in the ductility of martensitic steels at sub-zero temperatures, and strength at high temperatures due to over-tempering, are the two key factors that affect their operating temperatures.

* Annealed properties are typical for Condition A of ASTM A582.
** Hardened and tempered Condition T of ASTM A582 - Brinell hardness is specified range, other properties are typical only.
# Tempering of this steel at temperatures of 400 to 580°C should be avoided due to low impact resistance.
