SS 440C Round Bars

SS 440C Round Bars are martensitic stainless steel components with a high carbon content, engineered for superior surface hardness, excellent abrasion resistance, and reliable mechanical strength even at elevated temperatures. Comprising approximately 1.0 - 1.2% carbon and 16 - 18% chromium, SS 440C achieves remarkable mechanical strength after heat treatment. This grade can be hardened to Rockwell C60 and higher, making it one of the hardest stainless steels available in bar or rod form. The alloy also contains minor amounts of manganese, silicon, and molybdenum, contributing to its superior corrosion resistance under mild atmospheric and oxidizing environments.

These round bars and rods exhibit excellent dimensional stability post hardening, alongside good machinability in the annealed condition. They are typically supplied in quenched and tempered states, ensuring an optimal balance of toughness and rigidity. Surface finishes such as bright, black, peeled, or polished are available depending on end-use requirements. Their microstructure - predominantly martensitic - allows for precise grinding and lapping, particularly useful in applications where dimensional tolerances are critical. Furthermore, the alloy’s ability to resist deformation under mechanical stress makes SS 440C a preferred choice for precision-engineered components.

Crafted to exacting quality benchmarks, 440C stainless steel round bars and rods meet and exceed the stringent requirements of ASTM A276 and ASTM A484 standards. Common diameters range from 4 mm to 200 mm, with custom sizes available upon request. We cater to the quality needs of clients primarily across India, the United Arab Emirates (UAE), and the Kingdom of Saudi Arabia (KSA), ensuring prompt availability and consistent supply across a wide range of industrial sectors.

Applications of SS 440C Round Bars & Rods

SS 440C Round Bars and Rods are extensively utilized in applications that demand a unique combination of high strength, hardness, and moderate corrosion resistance. They are particularly valuable in the manufacture of components that must endure abrasive conditions while maintaining precision over time. These include bearings, valve components, surgical instruments, and high-load mechanical parts. Their ability to maintain edge retention and resist galling makes them ideal for knife blades, ball bearings, and rolling elements in bearing assemblies.

In the fields of mechanical engineering and precision tooling, SS 440C rods are widely utilized for crafting components such as punches, shafts, gauges, and die sets due to their outstanding hardness and dimensional stability. Their high hardness allows for prolonged tool life and reduced wear under repetitive motion and load-bearing conditions. They are also widely used in the production of aerospace components and turbine parts where high fatigue strength and dimensional consistency are critical. Thanks to their compatibility with heat treatment processes like quenching and tempering, SS 440C components can be custom-hardened to meet specific performance requirements, a feature that significantly expands their application versatility.

Additionally, SS 440C Round Bars serve as an excellent material choice for components operating in moderately corrosive environments such as marine hardware, food processing equipment, and pharmaceutical machinery. Although not as corrosion-resistant as austenitic grades, their superior mechanical properties provide a compelling trade-off in applications where strength and wear resistance are prioritized over chemical stability. They are also widely used in the defense sector for parts requiring both toughness and rigidity under dynamic stresses.
