AISI 440A / 440B / 440C UNS S44002 / S44003 / S44004 Stainless Steel Wire Bars
Grade 440 stainless family contains three types, 440A/440B/440C grades.
They are heat treated to extremely high hardnesses.
440A stainless has slightly less carbon than 440B and 440C giving it better machinability but less hardness.
The combination of good wear resistance and high hardness makes these alloys an excellent candidate for cutting
tools and knife blades. It also is often used for dental and surgical equipment.
