17-7PH is an austenite-martensitic precipitation-hardening stainless steel developed on the basis of 18-8CrNi, also known as controlled phase change stainless steel. After solution treatment, it is an unstable austenite structure with good plasticity and toughness. And workability, adjusted to make the austenite precipitated carbide composition change, and then after martensite transformation treatment, most of the structure is transformed into low toughness tempered martensite with better toughness, this state is the use of steel State, with good medium temperature mechanical properties. Corrosion resistance is better than general martensitic stainless steel.
