410S stainless steel coil, also called UNS S41008 martensitic steel coil.
410S stainless steel coils have good wear resistance with good formability and good weldability, it can be used as ultra-high strength material.
The rust resistance, corrosion resistance and weldability of 410s are better than 400 series of 420J2 stainless steel coil, which are used for parts with high toughness and impact load, such as automobile turbine blades, structural frames, linings, bolts, nuts, etc.
