What is 17.4 PH Material?

17-4 PH Stainless Steel is a precipitation-hardening martensitic stainless steel. Characteristic usage is seen in applications lacking high strength and a modest level of corrosion resistance. The strength and durability desired can be manipulated by the temperate range in the heat treatment method. High tensile strength, hardness, and exceptional corrosion resistance at high temperatures are all characteristics of 17-4 stainless steel. Gate valves, machinery for processing chemicals, pump shafts, gears, ball bearings, bushings, and fasteners are among the common applications for it.

Alloy 17-4PH (UNS S17400), Type 630, is martensitic stainless steel that precipitation-hardens with the addition of chromium, nickel, and copper. High strength, hardness, and exceptional corrosion resistance are all characteristics of 17-4PH.

Application of 17.4 PH Stainless Steel

Aerospace — structural and parts
Biomedical — hand tools
Chemical Processing
Food Process Equipment
Gate Valves
Mechanical Components
Nuclear Waste Processing and Storage
Oil and Gas Production — foils, helicopter deck platforms, etc.
Pulp and Paper

What is the Process, and Benefits of 17.4 PH Stainless Steel?

Type 17-4 PH stainless steel is the most widely used of all precipitation-hardening stainless steel. Its advantageous mix of attributes offers designers the chance to increase the durability of their goods while streamlining fabrication and frequently lowering costs. At temperatures up to 316°C (600°F), Type 17-4 PH, a martensitic precipitation-hardening stainless steel, offers an exceptional combination of high strength, superior corrosion resistance, and good mechanical qualities.

Process of 17.PH Stainless Steel

Heat Treatment
Cold Forming
Hot Forming
Cutting
Welding

Heat Treatment

Alloy 17-4PH is provided in the solution-annealed condition (Condition A). Mechanical properties may be altered by subsequent age-hardening treatments. These aging treatments are referred to as Conditions H900, H1025, H1075, H1150, H1150M, and H1150D.

Hot Forming

At 1742-2192°F (950-1200°C), heat uniformly. Hot forming must be followed by a thorough solution anneal, cooling to below 76°F (25°C), and aging at the necessary temperature. The intended mechanical qualities should influence the post-forming heat treatment.

Cold Forming

Alloy 17-4PH has limited cold-forming properties. Cold forming can only be undertaken on plates in fully annealed condition. Stress corrosion resistance is enhanced by re-aging at the precipitation hardening temperature after cold working.

Cutting

Plasma cutting and other thermal cutting methods ought to be avoided. The band saw, abrasive water jet, shearing, and machining are popular mechanical cutting operations.

Welding

Alloy 17-4PH is easily welded using the majority of common techniques, including SMAW, GTAW, PAW, and GMAW.

Benefits of 17.4PH Stainless Steel

Depending on the application, it is possible to harden something to adjust its strength and hardness.
High strength with moderate corrosion resistance
Can be machined in solution-treated and heat-treated conditions
Retains its mechanical properties and corrosion resistance up to roughly ~600°F
Great formability and weldability
Resists corrosion better than any of the commonly used hardenable (martensitic) stainless steels.
Superior resistance to corrosive material and high mechanical properties. This allows it to be used in marine environments.
Can be designed in such a way as to seal radioactive storage.
