What are 17-4PH stainless steel foils?
17-4 PH stainless steel foil, also called 630 precipitation hardening stainless steel foil.
17-4PH alloy is a precipitation, hardening, martensitic stainless steel composed of copper, niobium/columb.
After heat treatment, the mechanical properties of the foil product are more perfect, and can reach a compressive strength of up to 1100-1300 Mpa (160-190 ksi).
It has good corrosion resistance to the atmosphere and diluted acids or salts.
Its corrosion resistance is the same as 304 stainless steel foil and 430 stainless steel foil.
17-4PH stainless steel foil application
17-4PH is a martensitic precipitation hardening stainless steel.
It has high strength, high hardness, good welding performance and corrosion resistance.
It has been widely used in following industries:
- Oil field equipment
- Chemical process equipment
- Fittings and pump shafts
- Gears
- Paper mill equipment
- Aircraft parts
- Flanges and valves
- Other Precision Parts
