17-4PH Stainless Steel For Petroleum Mud Pump Petroleum Value
Manifold
Alloy 17-4PH (UNS S17400), Type 630, is a chromium-nickel-copper
precipitation-hardening martensitic stainless steel with an
addition of niobium. 17-4PH combines high strength and hardness
with good corrosion resistance. The alloy is furnished in the
solution annealed condition (Condition A).
The material is widely used in the aerospace, marine, paper,
energy, offshore and food industries for heavy-duty machine
components, bushings, turbine blades, couplings, screws, drive
shafts, nuts, measuring devices.
17-4 can be heat treated to high levels of strength and hardness,
and features corrosion resistance and machinability comparable to
austenitic 304 stainless. Being martensitic, 17-4 is
magnetic.Overaging (aging beyond the peak strength condition)
improves resistance to stress corrosion cracking.
