420
SUS420J1
20Cr13
In the quenched state, the hardness is high and the corrosion resistance is good. for steam turbine blades
Due to its magnetic properties, good edge retention, and fine surface finish, 420J1 is widely used in applications requiring sharpness, wear resistance, and aesthetic appeal.
This grade is typically supplied in cold-rolled strip form, with precision thickness and custom widths, making it ideal for manufacturers needing tight tolerances and high surface quality.
