1.Harden stainless steel 420J2 2.Hardness:54~55 HRC 3.Tough & sharp 4.Corrosion resistant,good for dive knife 5.Durable
Note that the final hardness level achieved is not only a factor of composition, but depends greatly on proper heat treatment and quenching.
CHEMICAL COMPOSITION
AISI 420J2 (X30Cr13) is easy for cutting and polishing. It is suitable to be used for bulk production of factory -made tool. It's idea for dive knife because of their low carbon content and excellent rust resistance force.
420J2 stainless steel has property of wear and corrosion resistance, high degree of hardness, but the price is relative low in group of stainless steel. It applys to the parts of weather proof.
