17-4PH stainless steel (ASTM) is a martensitic precipitation-hardening stainless steel, equivalent to the national standard 05Cr17Ni4Cu4Nb. This type of stainless steel has a low carbon content and high Ni and Cr content, making it weldable with good corrosion resistance. Additionally, the steel con

As the core component of mechanical transmission system, gear mainly faces two kinds of fatigue failure forms in long-term working state: bending fatigue fracture and contact fatigue pitting. In order to ensure its safe and reliable operation within the design life cycle, it is necessary to carry ou

After the gear has completed the heat treatment process (such as carburizing and quenching, induction hardening or nitriding), its surface hardness, core hardness and microstructure distribution directly determine its fatigue strength, wear resistance and overall life. In order to ensure that the he
