What core advantages does PH stainless steel have over regular stainless steel?

Compared with common austenitic 304 or 316 stainless steel, PH grades reach much higher hardness and tensile strength after aging without sacrificing basic anti-corrosion performance. Different from martensitic stainless steel, it avoids serious brittleness and large heat treatment deformation after strengthening. It maintains decent formability before aging, allowing stamping, forging and machining into complex shapes first, then achieving target hardness through mild aging. This characteristic perfectly meets the demand of precision machinery and aviation parts with tight dimensional tolerance standards.
