Περιγραφή προϊόντων

17-4PH Stainless Steel Round Bar

Material 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 most media

Industry Applications

Primary Applications:

Offshore equipment (foils, helicopter deck platforms)
Food processing industry
Pulp and paper manufacturing
Aerospace components (turbine blades)
Mechanical components
Nuclear waste casks

Condition 900	1310 min	1170 min	10 min	40 min
Condition 1150	930 min	724 min	16 min	28 min

Corrosion Performance

17-4PH stainless steel offers superior corrosion resistance compared to standard hardenable stainless steels, performing comparably to Alloy 304 in most environments. For applications with stress corrosion cracking risks, aging temperatures above 1022°F (550°C) are recommended.

Optimal Aging Temperatures

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

Note: The alloy may experience crevice or pitting corrosion when exposed to stagnant seawater for extended periods.

H1100	593	4	35	970-1120
H1150	621	4	33	930-1080

Manufacturing & Processing

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

Welding: Compatible with all conventional welding methods without requiring pre-heating. Proper design considerations are essential for high-strength applications.
