Grade Informations
17-4PH is a widely-used martensitic precipitation-hardening
stainless steel with a high concentration of chromium and nickel.
It has many favorable properties, including excellent strength,
good corrosion resistance, and excellent mechanical properties up
to 600 °F (316 °C).
The alloy also possesses good toughness when welded, while short
low-temperature heat treatments reduce warping and scaling.
Additionally, 17-4PH is easy to machine and fabricate.
Thanks to the beneficial properties, 17-4PH finds use in various
industries. Typical parts include mechanical seals, oil patch, and
pump shafts.
Furthermore, the alloy also finds use in the aerospace industry,
petroleum industry, and chemical industry, food processing
equipment, paper and pulp industry, nuclear waste processing and
storage, and general metalworking.
