Super Duplex 32750 Round Bar
Super Duplex 32750 Round Bar is a high-performance alloy bar known for its exceptional corrosion resistance and superior mechanical properties. Manufactured from a balanced mixture of austenitic and ferritic stainless steel, this material offers outstanding strength and durability, making it ideal for demanding industrial environments. The round bar form provides versatility for machining and fabrication across various applications.
Typically composed of approximately 25-28% chromium, 3-5% molybdenum, and 4-5% nickel, this grade exhibits excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. Its high yield strength and toughness make it suitable for components subjected to high pressure and aggressive chemical exposure. The product is commonly supplied in precise dimensional tolerances, ensuring compatibility with stringent engineering requirements.
Widely used in sectors such as oil and gas, chemical processing, marine engineering, and desalination plants, the alloy bars perform reliably in environments where chloride-induced corrosion is a concern. They are often utilized for manufacturing valves, pump shafts, flanges, and structural components that demand long service life and minimal maintenance. The material’s robust nature supports applications involving harsh seawater and acidic conditions.
Manufacturers and exporters ensure that the round bars comply with international standards like ASTM A182 and UNS S32750, facilitating seamless integration into global supply chains. Quality assurance includes rigorous testing such as hardness, tensile strength, and non-destructive examination to meet client specifications. Packaging and documentation are tailored for safe transport and regulatory compliance, making these bars readily exportable to diverse industrial markets.

Manufacturing Process & Heat Treatment of Super Duplex 32750 Round Bar
Annealing
Annealing of Super Duplex 32750 round bars is performed to relieve internal stresses and improve ductility. The process involves heating the material to a temperature range of 1020°C to 1100°C, followed by controlled cooling. This treatment enhances the toughness and corrosion resistance of the steel.
Forging
The forging of Super Duplex 32750 round bars is conducted at high temperatures, typically between 1100°C and 1200°C. This process improves the mechanical properties of the material by refining the grain structure and increasing strength. The forged bars are then allowed to cool gradually to room temperature.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1050 - 1100 | Oil | Increase hardness and strength |
| Tempering | 300 - 600 | Air | Reduce brittleness and improve toughness |
| Stabilizing | 800 - 900 | Air | Enhance resistance to stress corrosion cracking |
The combination of these processes ensures that Super Duplex 32750 round bars achieve optimal mechanical properties and corrosion resistance, making them suitable for demanding applications in various industries.
