Top-Quality 17-4 PH Stainless Steel Plates

17-4PH stainless steel belongs to the group of martensitic precipitation-hardening alloys characterized by high strength, corrosion resistance, and heat treatment opportunities. This material is characterized by an excellent balance of mechanical and chemical performance and is ideal for use in aerospace, oil and gas, chemical processing and power generation industries. 17-4PH plates are manufactured and distributed by Duplex Steel & Alloys, and they are of top quality, meeting international standards and accreditation.

Chemical Composition and its Advantages

The use of 17-4PH stainless steel is as a result of its controlled composition of the various alloying elements. Key elements and their benefits include:

• Chromium (15-17.5%): Improves the corrosion properties of the material and provides high performance in conditions that are mildly corrosive such as seawater and in acidic solutions.
• Nickel (3-5%): Helps enhance the hardness and also increases resistance to stress corrosion cracking in high pressure or high temperature service.
• Copper (3-5%): Promotes the precipitation-hardening process which enhances the material during heat treatment.
• Niobium (0.15-0.45%): Guarantees the grain refinement that increases tensile strength and ductility.
• Low Carbon Content (≤0.07%): Enhances weldability and minimises the probability of weld becoming brittle or cracking.

This accurate alloying leads to a material that has good strength and corrosion resistance even in harsh working conditions.

Mechanical Properties and Benefits

17-4PH is one of the most popular materials for applications where strength, durability and reliability are important. Post-heat treatment, the material achieves remarkable performance metrics:

• Tensile Strength: It can reach 1310 MPa, which is suitable for load-bearing structures. This is particularly advantageous where high stresses are encountered, such as in aerospace components and apparatus used in the production of heavy industries.
• Yield Strength: It ranges from 725 to 1170 MPa, this enables the material to undergo deformation under large loads like those used in pressure vessels and turbine shafts.
• Elongation at Break: Around 10-20 % would be sufficient to control dynamic loads and impacts without failure.
• Hardness: The ageing treatments can give up to 38 HRC, making the material ideal for wear in abrasive or high-friction applications.

These mechanical properties offer excellent performance in areas where high fatigue strength, wear and high pressure are expected.

Comparison with 15-5PH Stainless Steel

It is also compared with 15-5PH stainless steel, which is also a precipitation hardening martensitic steel. Both grades have similar compositions, but 15-5PH has slightly improved toughness and weldability because of the fine structure of the chemical composition. However, 17-4PH is superior in strength and corrosion resistance, especially after heat treatment; thus, it is suitable for use in offshore platforms, high stress aerospace parts and chemical reactors.

Compliance and Third Party Inspection

At Duplex Steel & Alloys, compliance with stringent international standards such as ASTM A564, AMS 5604, and EN 10088-3 underscores the quality and reliability of our 17-4 PH stainless steel plates across diverse industries. We employ rigorous testing methods validated by third-party inspections to ensure adherence to these benchmarks.

Chemical Analysis confirms that the alloy composition meets precise specifications, ensuring superior corrosion resistance and consistent mechanical properties.

Mechanical Testing, including tensile strength, yield strength, and elongation tests, verifies the material’s ability to perform in critical, high-stress applications.

Hardness Testing guarantees uniform hardness across the plates, a key factor in ensuring durability and wear resistance.

Ultrasonic Testing (UT) identifies any internal defects, ensuring the structural integrity of every plate.

These tests validate the superior quality of our products and enhance customer confidence in our brand. They enable us to consistently deliver materials that excel in demanding environments.

Applications of 17-4PH stainless steel plates

17-4PH stainless steel plates are versatile, serving a range of industries with their exceptional properties:

• Aerospace: Due to its high strength-to-weight ratio and fatigue resistance, 17-4PH is suitable for use in aircraft structures, turbine blades and landing gear.
• Oil & Gas: Its excellent resistance to stress corrosion cracking and good performance under high pressure make it ideal for use in subsea platforms, heat exchangers and pipelines.
• Chemical Processing: Their resistance to mild acids and alkalis, as well as their high strength, allow them to be used in reactors and agitators.
• Power Generation: Heat resistance and fatigue strength allow its application in turbines, boiler parts, and heat exchange equipment.

These applications show how the material performs in a variety of applications and the robustness of the material.
