Stainless Steel 17-4ph Round Bar in India
Stainless Steel 17-4ph Round Bar in India is a premium-grade alloy widely sought after for its exceptional strength, corrosion resistance, and excellent mechanical properties. This precipitation-hardening stainless steel combines the corrosion resistance of chromium with the high strength of copper and niobium, making it ideal for demanding industrial applications. Indian manufacturers produce these round bars adhering to strict quality standards, ensuring consistency and reliability.
The product is typically available in various diameters and lengths, catering to diverse engineering needs. Its hardness can be enhanced through heat treatment processes, offering flexibility in achieving the desired mechanical characteristics. With a typical composition including 15–17.5% chromium, 3–5% nickel, and 3–5% copper, this alloy exhibits high tensile strength and good toughness, even in sub-zero temperatures.
Industries such as aerospace, chemical processing, petrochemical, and power generation extensively use these bars for components like shafts, gears, valves, and structural parts. Their high resistance to oxidation and stress corrosion cracking makes them suitable for harsh environments, including marine and acidic conditions. The material’s machinability and weldability further enhance its application potential.
Producers in India focus on export readiness by complying with international standards such as ASTM A564 and AMS 5643, ensuring that these stainless steel bars meet global quality benchmarks. Packaging and documentation are tailored to facilitate smooth customs clearance and timely delivery, supporting the stringent requirements of overseas industrial buyers. This makes Indian stainless steel 17-4ph round bars a competitive option in the global marketplace.
With robust manufacturing infrastructure and advanced testing capabilities, suppliers in India offer these alloy bars with certifications like material test reports (MTRs), traceability, and third-party inspection reports. This commitment to quality assurance instills confidence for buyers seeking durable and high-performance stainless steel components for critical applications worldwide.

Manufacturing Process & Heat Treatment of Stainless Steel 17-4PH Round Bar
Annealing
Annealing of Stainless Steel 17-4PH is performed to relieve internal stresses and improve ductility. The process involves heating the material to a temperature range of 1040-1120°C, followed by a controlled cooling process. This treatment enhances the material's mechanical properties and prepares it for subsequent processing.
Forging
The forging process for Stainless Steel 17-4PH involves heating the steel to a temperature of approximately 1100-1200°C and then shaping it under mechanical force. This process improves the grain structure and provides enhanced strength and toughness. Forged round bars are then subjected to further processing, including heat treatment.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1040-1120 | Oil or Water | To increase hardness and strength |
| Tempering | 480-620 | Air | To relieve stress and improve toughness |
| Solution Treatment | 1040-1100 | Water | To dissolve precipitates and enhance corrosion resistance |
The combination of these manufacturing processes and heat treatments ensures that Stainless Steel 17-4PH round bars achieve the desired mechanical properties, making them suitable for various industrial applications including aerospace, chemical processing, and oil and gas industries.
