440A 440B 440C stainless steel strip coil with heat Resistance

  Grade 440C stainless steels are high carbon steels, which attain the highest hardness, wear resistance and strength of all stainless steel grades after heat treatment. These properties make this grade suitable for applications such as valve components and ball bearings. Grade 440A and 440B stainless steels, on the other hand, have similar properties - except for a slightly lower percentage of carbon in grade 440A.

  All three forms of grade 440 steels are commonly used. However, grade 440C is more readily available than the other standard grades. Grade 440F, a free-machining type of grade 440 series, is also available with a high carbon content similar to that of grade 440C. Martensitic steel grades are high-hardness steels, usually fabricated using techniques that require hardening and tempering treatments.

Difference Between Stainless Steel Sheet,Plate&Foil:
 

Here are few points to recognised sheet, plate or foil:

• If thickness greater than 6.35 mm is called a Stainless Steel Plate.

• If thickness greater than 0.15 mm and less than 6.35mm is called a Stainless Steel Sheet.

• If thickness less than 0.15mm is then its a Stainless Steel Foil.
