Hot Rolled and Forged Hastelloy C-22 Round Bar: Black and Bright Polished Bar in Custom Length

Premium Corrosion Resistance for Demanding Applications

Our Hastelloy C-22 round bars represent the pinnacle of nickel-chromium-molybdenum-tungsten alloys, engineered to deliver exceptional performance in the most aggressive corrosive environments. Available in both hot rolled and forged conditions, and in your choice of black (as-supplied) or bright polished surface finishes, we provide the material solution tailored to your specific technical and aesthetic requirements.

Product Forms & Availability

• Hot Rolled Round Bars: Cost-effective solution with good mechanical properties, suitable for a wide range of general corrosion applications.

• Forged Round Bars: Superior mechanical strength, grain structure, and directional properties achieved through the forging process. Ideal for high-integrity components like valve stems, fasteners, and pump shafts subject to high stress.

• Custom Lengths: We specialize in supplying round bars cut to your exact specifications, minimizing waste and reducing your machining time and cost.

Surface Finishes

• Black Bar: Supplied in a descaled, as-rolled or as-forged condition. This economical finish is perfect for parts that will undergo subsequent machining or where surface appearance is not critical.

• Bright Polished Bar: Cold drawn and polished to a smooth, shiny finish. This offers excellent dimensional accuracy, a superior surface appearance, and is often used for applications where a clean, finished surface is required with minimal post-processing.

Key Features & Material Advantages of Hastelloy C-22

• Exceptional, All-Around Corrosion Resistance: Hastelloy C-22 offers outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking.

• Versatile Oxidizing and Reducing Media Capability: It performs excellently in both oxidizing and reducing environments, including those containing chlorides.

• Superior Resistance to Wet Chlorine and Mixed Acids: An ideal choice for handling sulfuric acid, nitric acid, acetic acid, and other aggressive chemical media.

• Excellent Weldability: Hastelloy C-22 is readily welded using common techniques and shows low susceptibility to weld zone degradation.

• High Thermal Stability: Maintains its properties over a wide temperature range.
