17-4PH (heat treatment)

MIM 17-4 PH (precipitation hardening grade)
Because the carbon content of MIM 17-4PH alloy is lower than that of 400 series stainless steel, its products have better corrosion resistance. Through heat treatment, the product can have better product hardness and higher product strength.
