17-4PH is a martensitic precipitation hardening stainless steel .17-4PH performance characteristics are easy to adjust the intensity level can be adjusted by changes in heat treatment process. Martensitic transformation and the formation of precipitation-hardening phase aging is the main means of strengthening, 17-4PH attenuation properties, corrosion fatigue and anti-drop performance strong.

     Application areas:

     · Offshore platforms, helicopter deck, and other platforms

· Food Industry

· Pulp and paper industry

· Aerospace (turbine blades)

· Mechanical components

· Drums of nuclear waste

17-4PH 17-4PH alloy is a precipitation hardening martensitic stainless steel.

17-4PH alloy is copper, niobium / columbium form of precipitation hardening, martensitic stainless steel.

This class has a high strength, hardness (up to 300 º C/572 º F) and anti-corrosion properties.

After heat treatment, the mechanical properties of the product more complete, can reach up to 1100-1300 mpa (160-190 ksi) of compressive strength.

This class can not be used above 300 º C (572 º F) or very low temperatures, dilute acid or its salt air and has good corrosion resistance, corrosion resistance and its 304 and 430 the same.
