Hastelloy Round Bars
Hastelloy Round Bars Manufacturer & Exporter in India
Hastelloy round bars are high-performance nickel-based alloy products designed for extreme corrosion resistance in aggressive industrial environments. Manufactured from advanced alloys containing nickel, chromium, and molybdenum, these bars deliver exceptional resistance to oxidation, pitting, crevice corrosion, and chemical attack in applications where conventional materials fail. Industries relying on hastelloy round bars include chemical processing, marine engineering, pollution control systems, oil and gas, and power generation, where material integrity under harsh conditions is non-negotiable.
Among the various grades available, Hastelloy C276 round bar and Hastelloy C22 round bar are the most commonly used. Hastelloy C276 round bars are known for their outstanding resistance to strong oxidizing and reducing chemicals, making them suitable for harsh industrial environments. On the other hand, Hastelloy C22 round bars offer superior resistance to pitting and crevice corrosion, especially in chloride-rich environments. These alloys are available in the form of hastelloy rods, hastelloy bar stock, forged hastelloy round bars, and hot rolled hastelloy round bars, allowing engineers to select the appropriate material for demanding applications.

Types of Hastelloy Round Bars
We manufacture stainless steel round bars in multiple grades and finishes to meet diverse industrial requirements:
Hastelloy C22 Round Bars
Hastelloy C276 Round Bars
Hastelloy C22 Round Bars
Hastelloy C22 round bars are nickel-chromium-molybdenum alloy bars designed for excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. These bars provide superior protection in oxidizing and reducing environments, making them widely used in chemical processing plants, pharmaceutical equipment, and pollution control systems. Hastelloy C22 round bars are also known for their excellent weldability and fabrication properties.
Hastelloy C276 Round Bars
Hastelloy C276 round bars are one of the most versatile nickel alloys used in highly corrosive environments. These bars provide exceptional resistance to a wide range of aggressive chemicals, including sulfuric acid, hydrochloric acid, and chlorine compounds. Because of their excellent corrosion resistance and durability, hastelloy C276 rods and bar stock are widely used in marine, chemical, and oil & gas industries.
How Hastelloy Round Bars Are Manufactured
Hastelloy round bars are produced through three primary methods, each suited to different application requirements:
- Hot Rolled: Bars are heated above recrystallization temperature and passed through rolling mills. This process produces larger diameter bars with slightly rougher surface finish, ideal for applications where subsequent machining will be performed.
- Forged: Material is shaped under high compressive forces, creating superior grain structure and mechanical properties. Forged hastelloy round bars offer enhanced strength and are specified for critical stress-bearing components.
- Cold Drawn (Bright Bars): Bars are drawn through dies at room temperature to achieve precise dimensions and smooth, bright surface finish. Bright bars are used where tight tolerances and minimal machining are required.
