About 17-4PH Stainless Steel Bar / Alloy17-4PH UNS-S17400
Also known as AISI Grade 630, stainless steel alloy grade 17-4PH is a precipitation hardening stainless steel which has extremely high strength and hardness, combined with good ductility and toughness. It has excellent corrosion resistance, approaching that of stainless steel grade 304. Designers and engineers often choose the alloy for its high strength, with corrosion resistance superior to most other high strength steels.
Typical Applications
High strength bolting and fasteners in aerospace and chemical plant applications. The alloy has been used in the petrochemical, petroleum, paper and food processing industries and has performed well. The alloy is also used for boat propeller shafts, where it is supplied as precision straightened, centreless ground shafting. It is also available as investment castings for uses such as boat fittings.

Corrosion Resistance
17-4PH has excellent corrosion resistance. It withstands corrosive attack better than any of the standard hardenable alloys and approaches the corrosion resistance of the standard austenitic stainless steel grade 304 in most media.
In rural and mild industrial atmospheres 17-4PH has excellent corrosion resistance. When exposed to sea coast atmospheres 17-4PH will slowly develop an overall light rusting and pitting. It is used successfully in salt water as boat shafting, with cathodic protection.

Fabrication17-4PH can be cold formed to a limited extent in the annealed condition. Severe cold working should be done in the H1150 condition to reduce the possibility of cracking. The steel should be re-aged after cold forming to restore the best combination of properties.
17-4PH is readily hot forged. During heat treatment or forging, protective atmospheres containing carbon or nitrogen should be avoided. These elements can be absorbed into the steel surface and give soft austenitic skin. If a protective atmosphere is required argon or helium is recommended.
Machinability
17-4PH can be machined in both the solution annealed condition and the precipitation hardened condition. Because the final heat treatment temperature is low, 17-4PH can be machined to final dimension in the annealed condition and then aged without significant dimensional change or scaling unless the component is large, when allowance should be made for contraction on aging.
In the annealed condition machining is only marginally different from 300 series austenitic stainless steels. In the H900 condition the machining rate is 60% of that for annealed material.
Weldability
17-4PH has excellent weldability under production conditions, with procedures similar to 300 series stainless steels. All welding methods can be applied. 17-4PH does not require pre-heat up to 100mm section.
AWS A5.4 E630 Covered Electrodes and AWS A5.9 ER630 filler metals are used for welds of matching strength. For matching corrosion resistance, grade 308 or 309 consumables may be used.
Weld metal properties approach those of the parent metal. Post weld heat treatment is required to achieve full strength. Single pass welds are precipitation hardened, multipass welds must be solution annealed first.
Heat Treatment
The material is usually supplied solution annealed. It can be heat treated to a range of combinations of strength & ductility. Please ask Austral Wright Metals for advice.
Castings
17-4PH can be cast readily by most processes. The cast equivalent to 17-4PH is CB-7Cu-1, as specified in ASTM A747. The properties are slightly inferior to those of wrought material.
