Product Description

17-4PH 630 H9 Stainless Steel Round Bar

Overview

17-4 Precipitation Hardening (Type 630) is a chromium-copper precipitation hardening stainless steel designed for applications requiring high strength and moderate corrosion resistance. This alloy maintains high strength up to approximately 600°F (316°C).

Key Characteristics

Precipitation hardening martensitic stainless steel with copper and niobium additions
High strength and hardness maintained up to 572°F (300°C)
Mechanical properties optimized through heat treatment
Very high yield strength up to 1100-1300 MPa (160-190 ksi)
Corrosion resistance equivalent to Alloy 304 or 430 in many environments

Applications

Offshore equipment (foils, helicopter deck platforms)
Food processing industry components
Pulp and paper manufacturing equipment
Aerospace components (turbine blades)
Mechanical components and nuclear waste casks
Engine components and boat propeller shafts
Plastic molding dies, valves, and gears

Physical Properties

Property	Value
Density	7750 kg/m³
Thermal Expansion (0-100°C)	10.8 µm/m/°C
Thermal Conductivity (100°C)	18.4 W/m·K

Electrical Resistivity	800 nΩ·m

Alternative Material Comparison

Alternative Grade	Selection Considerations
431	Higher toughness, better availability in some sizes
416	Free-machining martensitic steel, better for repetition machining, lower cost
316	Higher corrosion resistance but much lower strength
2205	Much better corrosion resistance with lower strength (but higher than 316)

Heat Treatment

Solution Treatment (Condition A): Heat to 1040°C for 0.5 hours, then air-cool to 30°C. Small sections may be oil quenched.

Age Hardening: Performed at low temperatures to achieve required mechanical properties. Typical conditions include:

Condition	Temperature (°C)	Time (h)	Typical Hardness (HRC)
H900	482	1	44
H925	496	4	42
H1025	552	4	38
H1150	621	4	33

Fabrication Properties

Welding: Can be welded using all conventional methods without pre-heating. Design carefully to prevent weldment stresses.

Machining: Best machined in solution-treated condition with rates similar to grade 304 stainless steel.

Corrosion Resistance

17-4PH withstands corrosive attacks better than standard hardenable stainless steels and is comparable to Alloy 304 in most media. For optimal stress corrosion cracking resistance, aging temperatures above 550°C are recommended.
