Supplier of 17-4 PH Stainless Steel Round Bars

Duplex Steel & Alloys is a leading manufacturer and supplier of high-performance stainless steel products, based in Mumbai, India. Renowned for delivering exceptional quality and reliability, we serve the oil and gas, chemical, marine, aerospace, and power generation sectors. We offer a vast range of superior 17-4 PH stainless steel round bars that are known for its high tensile strength, corrosion resistance and durability in harsh conditions.

Benefit of 17-4 PH SS Fasteners

The outstanding performance of 17-4 PH stainless steel is a direct result of their precise chemical composition:

• Chromium (15-17.5%): Resists oxidation and corrosion, thus the round bars are ideal for severe applications such as marine and chemical applications.
• Nickel (3-5%): Improves the toughness and corrosion resistance of 17-4PH SS round bars in acidic and chloride containing environments.
• Copper (3-5%): An important component providing high strength and hardness after heat treatment.
• Carbon (≤0.07%): Retains the 17-4PH SS bars hardness and wear resistance while enhancing their machinability.
• Niobium + Tantalum (0.15-0.45%): It minimizes intergranular corrosion of the alloy and improves weldability of 17-4PH SS Round Bars.
• Manganese (≤1.00%) & Silicon (≤1.00%): Enhance the bar strength and optimize the production process of stainless steel 17-4PH SS bars.

This balanced composition forms martensitic alloy bars with high mechanical features and durability in their performance.

Mechanical Properties and Applications

1. High Strength:

17-4 PH SS round bars offer superior mechanical properties which include:

• Tensile Strength: 1000–1600 MPa that ensures high load-carrying characteristics for aerospace and automotive applications.
• Yield Strength: 960–1480 MPa does not deform under high loads, making our bars suitable for high pressure equipment such as valves and fasteners.
• Elongation: 10-15% provides for the ability to shape machine with high accuracy.
• Hardness: Up to 40 HRC (H900 condition) provides increased wear resistance to applications in the construction and marine equipment sectors.

These properties make 17-4 PH bars very ideal for harsh working conditions thus making it strong and durable in many sectors.

2. Corrosion Resistance: Chromium and nickel in its composition offer excellent resistance to oxidation and atmospheric corrosion and thus long life in severe operating conditions.
3. Heat Treatment Versatility: Stainless steel 17-4 PH bars can be heat treated by means of a low temperature precipitation process that helps to achieve mechanical properties of hardness and toughness.

Applications Across Industries

• Aerospace: These bars are suitable for light weight, high strength applications like landing gears and other structural members conforming to AMS and ASTM specifications.
• Oil & Gas: SS 17-4 PH bars offer excellent corrosion resistance in chloride containing and H2S service conditions thus making it suitable for offshore platforms and pipelines.
• Power Generation: High-temperature tolerance makes it suitable for turbine blades and boilers, with UT and MTC certifications for quality assurance.
• Automotive: High strength and wear resistance of 17-4 PH SS round bars make them suitable for precision-engineered components like gears, shafts, and fasteners in performance vehicles.

Standards and Certifications

Our 17-4 PH stainless steel round bars meet the highest global standards in terms of quality, reliability and performance in demanding applications.

We conduct rigorous mechanical tests to guarantee compliance with ASTM A564, which outlines the characteristics of precipitation-hardening stainless steel, and AMS 5643, tailored for aerospace-grade materials. These include tensile strength, hardness, and impact toughness evaluations to ascertain that the material will satisfy high performance. Compliance with EN 10088, the European standard for stainless steels, underscores our commitment to exceptional corrosion resistance and mechanical integrity.

Our certifications, including ISO 9001 for quality management and ASME compliance, reflect our dedication to precision and excellence. Non-destructive tests such as ultrasonic inspection detect internal flaws, while chemical analysis verifies material composition. These processes guarantee superior quality and global trust in every bar we produce.

Comparison: Stainless Steel 17-4 PH vs. SS 316, SS 304

17-4 PH stainless steel offers superior strength, hardness, and durability, making it ideal for high-stress applications like aerospace and marine. It excels in mechanical properties but has moderate corrosion resistance. SS 304, the most cost-effective, provides good corrosion resistance in mild environments but lacks the strength of 17-4 PH. SS 316 offers superior corrosion resistance, especially in chloride environments, making it ideal for marine and chemical industries, but its mechanical strength is lower than 17-4 PH. Thus, 17-4 PH stainless steel is best for strength compared to the two.

Third-Party Testing

We partner with trusted third-party laboratories to ensure our 17-4 PH stainless steel round bars consistently meet the highest standards of quality and performance. These independent tests validate the integrity of our products and reinforce our commitment to excellence.

• Chemical Composition Analysis ensures the alloy’s precise chemical makeup aligns with 17-4 PH specifications, guaranteeing optimal strength, corrosion resistance, and reliability in critical applications.
• Tensile Testing evaluates the material’s strength, yield, and elongation, confirming it can withstand demanding operational stresses with consistent mechanical performance.
• Impact Testing measures toughness and resistance to sudden stresses, verifying the material’s durability in dynamic or extreme environments.

These rigorous evaluations validate the quality of our materials and enhance trust in our brand, ensuring our 17-4 PH round bars deliver unmatched reliability across industries.
