What is Hastelloy Steel and its Features

Many nickel-based steel alloys exhibit high resistance to corrosion, and Hastelloy is one of the best. In addition to outstanding resistance to all manner of pitting and cracking, parts made from Hastelloy metal blends tend to find good use across a wide range of chemical applications that might otherwise oxidize the metal. Additional elements such as molybdenum and chromium round out the profile of an alloy that is widely regarded as one of the world’s toughest.

Hastelloy Properties

Hastelloy is a nickel-molybdenum alloy designed to withstand high temperatures and high concentrations of reducing acids. It is not impacted by grain-boundary carbide precipitation after welding because it is not affected by grain-boundary carbide precipitation. It can be utilized even if it is welded.

Hastelloy C-276 Composition

Hastelloy is a nickel-based superalloy with more than 50% nickel and significant amounts of molybdenum and chromium. There are also small amounts of cobalt, tungsten and manganese in Hastelloy C-276. As with most industrial alloys, Hastelloy C-276 is defined in weight percent (wt%), with a minimum and maximum alloying tolerance.

For example, a small amount of sulfur does NOT improve the alloy properties, but companies expect to see a certain amount of sulfur contamination, below the maximum alloying tolerance.

Mechanical Properties

Although Hastelloy C-276 is primarily used for corrosive applications, rather than structural applications, the alloy still boasts good mechanical properties. Alloy C-276 is about as stiff and strong as martensitic steel, and can be used at relatively high temperatures.
