Stainless Steel Sheet And Plate SUS440A / AISI 440A / EN 1.4109 /
AISI 440A ( UNS S44002 ) stainless is a high-carbon martensitic stainless steel developed to provide
stainless properties with maximum hardness.
It is magnetic in both the annealed and hardened conditions.
Maximum hardness and corrosion resistance are available only in the
hardened or hardened and stress
relieved conditions, so the alloy is not used in the annealed or
annealed and tempered conditions.
Dental and surgical instruments and cutlery are frequent
applications for Type 440A.
Type 440A Stainless Steel in coils and cut lengths in thicknesses
0.1mm up and widths up to and including 250mm.
440A stainless High-carbon chromium steel. Provides stainless
properties with excellent hardness.
Attains a hardness of Rockwell C 56 and maximum toughness when

440A is a high carbon martensitic stainless steel, this alloy can
be heat treated to extremely high hardnesses.
It 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
this alloy an excellent candidate for cutting tools and knife
It also is often used for dental and surgical equipment.
