We are professional AISI 440A/440B/440C/1.4109/1.4112/1.4125/UNS S44002/S44003/S44004 Stainless Steel Bearings factory from china
The 440 grades form a series of high carbon martensitic stainless steels. They have basic corrosion resistance and extremely high hardness and wear resistance.
Approximate Composition – 16% Cr, 0.60-1.0% C plus Mo and V in EN grades (Exact composition ranges vary between EN and ASTM standards. Equivalents much looser than for most grades).
This grade combines the following characteristics:
This series of grades give the highest level of strength/hardness in any martensitic stainless steel. Consequently, they are used where a basic level of corrosion resistance is required coupled with high wear resistance or blade sharpness. They are usually supplied in the annealed condition for improved machinability and then hardened and tempered to develop the high hardness.
Applications which illustrate these features include:
Bearings, valves, knife blades, surgical instruments, tools, moulds, dies.
