What is Hastelloy C276 round bar ?

Hastelloy C276 is a nickel based alloy that has chromium, molybdenum, etc., in its chemical composition. The Hastelloy C276 round bar shows good resistance to corrosion along with high ductility, weldability and formability. It can also withstand chloride ion related stress corrosion cracking. They are easy to fabricate using standard techniques and the material is quite versatile. EN 2.4819 rounds can also resist pitting and crevice corrosion.

The Hastelloy c276 annealed bar shows good resistance in oxidizing and reducing environments. They are used in flue gas desulfurization systems. The 2.4819 Hastelloy hot rolled bars can withstand a wide range of chemical environments, like organic and inorganic media. They can also resist seawater and brine solution. The Hastelloy alloy c276 cold drawn bar can work in chlorine gas and dioxides.

Where exactly alloy C276 round bar suitable to use ?

The alloy C276 round bar can be used in a wide range of environments in moderately oxidizing and highly reducing solutions. They show good resistance to different types of chemical and chloride solutions. The alloy C276 bright bar can be used in the recovery and processing of sour gas that contains hydrogen sulphides, carbon dioxides and chlorides. They can also be used in chemical, petrochemical, oil & gas, marine & offshore, aerospace and power generation industries. The round bars are also suitable for desalination plants, pollution control, etc.

What factors influence the thickness of nickel alloy C276 flat bar?

Choose the thickness of the nickel alloy C276 flat bar based on the following factors:

  • The load and stress required by the application.
  • The level of corrosion that the flat bar needs to withstand.
  • Environmental factors like temperature, exposure to chemicals, etc.
  • The specific mechanical requirements like tensile & yield strengths, hardness, etc.
  • Design standards and codes that provide guidelines on the minimum thickness.
  • Fabrication processes like cutting, bending and machining can also influence the thickness.
What are the maximum tolerances limit for Hastelloy c276 hex bar ?

The minimum tolerance limit of the Hastelloy c276 hex bar depends on:

  • The diameter and length tolerance specify the acceptable size variation of the bar’s cross-section.
  • The straightness tolerance defines how much the hex bar can deviate from being straight.
  • The surface finish and corner radii tolerance also have an impact.
