Product Description

17-4PH Stainless Steel Round Bar

Overview

17-4PH (Type 630) is a chromium-copper precipitation hardening stainless steel offering high strength and moderate corrosion resistance. This martensitic stainless steel maintains high strength up to 600°F (316°C) and is available in solution-treated condition for easy machining.

Key Properties

Precipitation hardening martensitic stainless steel
High strength and hardness up to 572°F (300°C)
Excellent mechanical properties after heat treatment
Very high yield strength up to 1100-1300 MPa (160-190 ksi)
Corrosion resistance equivalent to Alloy 304 or 430

Applications

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

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 with minimal distortion.

H1150	621	4	33	930-1080

Corrosion Resistance

17-4PH stainless steel offers superior corrosion resistance compared to standard hardenable stainless steels, comparable to Alloy 304 in most media. Optimal aging temperatures for specific environments:

1022°F (550°C) - Optimal for chloride media
1094°F (590°C) - Optimal for H2S media

Note: Avoid exposure to stagnant seawater to prevent crevice or pitting corrosion.

Fabrication

Welding: All conventional welding methods can be used without pre-heating requirements.

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

Alternative Grades Comparison

Alternative Grade	Reason for Selection
431	Higher toughness, better availability in some sizes
416	Free-machining martensitic steel, lower cost
316	Higher corrosion resistance but lower strength
2205	Much better corrosion resistance with moderate strength
