17-4PH bolt alloy is a precipitation hardened martensitic stainless steel composed of copper, niobium/niobium.
Characteristics: After heat treatment, the mechanical properties of the product are more perfect, and it can achieve a compressive strength of up to 1100-1300 Mpa (160-190 ksi).
The 17-4PH screw is a martensitic precipitation hardening stainless steel. The performance characteristic of 17-4PH is that it is easy to adjust the strength level, which can be adjusted by changing the heat treatment process The formation of precipitation hardening phase through martensitic transformation and aging treatment is its main strengthening method. 17-4PH has good attenuation performance, strong corrosion fatigue resistance, and water droplet resistance.
Application fields:
·Offshore platforms, helicopter decks, other platforms
·Food industry
·Pulp and paper industry
·Aerospace (turbine blades)
·Mechanical components
·Nuclear waste bin
