A268 TP410 is a typical martensitic chromium-alloy steel grade. It does not have the nickel content and owns the following characteristic:
-Harding by heat treatment
-High hardness with good ductility
-Good corrosion resistance capability
-Good wear corrosion resistance
-High cold-deformation property
TP410 is the basic and typical martensitic steel alloy. It has the high hardness with good ductility and a relative limited corrosion-resistant capability.
TP410 material does not have the nickel content and has a relative low material cost. Besides, it can replace some austenitic steel grades under some mild corrosion condition.
