Material Description
17-4 Precipitation Hardening (Type 630) is a chromium-copper precipitation hardening stainless steel used for applications requiring high strength and moderate corrosion resistance. High strength is maintained to approximately 600°F (316°C).
General Properties
Alloy 17-4 PH is a precipitation hardening martensitic stainless steel with Cu and Nb/Cb additions. The grade combines high strength, hardness (up to 572°F / 300°C), and corrosion resistance. Mechanical properties can be optimized with heat treatment, achieving very high yield strength up to 1100-1300 MPa (160-190 ksi).

Alternative Grades
Grade Reasons for choosing 17/4PH (630)
431 431 Has higher toughness than 17/4PH. Better availability in some sizes.
416 Free-machining martensitic stainless steel - better for repetition machining. Lower cost.
316 Higher corrosion resistance of 316 to resist more severe environments, but with much lower strength than 17/4PH.
2205 Much better corrosion resistance than 17/4PH, with a lower strength (but not as low as 316).
Corrosion Resistance
Grade 630 stainless steels have good corrosion resistance in many environments. They exhibit improved resistance against stress corrosion cracking when aged at 550°C or more. However, grade 630 steels are less resistant in solution treated Condition A and should not be used in this condition despite considerable hardness.
Heat Resistance
Grade 630 stainless steels have good resistance to oxidation. However, long-time exposure to temperatures of 370 to 480°C should be avoided to prevent loss of toughness at ambient temperature. These grades should not be used above age-hardening temperature to avoid reduction of hardness and mechanical properties.
Heat Treatment
Solution treatment (Condition A) - Grade 630 stainless steels are heated at 1040°C for 0.5 h, then air-cooled to 30°C. Small sections can be oil quenched.
Hardening - Grade 630 stainless steels are age-hardened at low temperatures to achieve required mechanical properties. During the process, superficial discoloration occurs followed by shrinkage at 0.10% for condition H1150, and 0.05% for condition H900.
Condition Hardening Temp (°C) Time (h) Typical Hardness Rockwell C Tensile Strength (MPa)
A Ann - 36 1100
H900 482 1 44 -
H925 496 4 42 1170-1320
H1025 552 4 38 1070-1220

H1100 593 4 35 970-1120
H1150 621 4 33 930-1080
Welding & Machining
Welding: Grade 630 stainless steels can be welded using all conventional methods and do not require pre-heating. Care should be taken in designing and welding high strength steels to prevent weldment stresses.
Machining: Grade 630 stainless steels can be machined in their solution-treated condition. They have machining rates similar to grade 304 steels.
