Hastelloy Alloys

Stainless steel, or Hastelloy®, metals and alloys, are well known for the fact that they can withstand high temperatures and corrosion. Haynes International was the first company to develop this type of super alloy after the invention of stainless steel in 1913.

In addition to offering incredible strength and ductility under stress, Hastelloy® alloys are also very formable and ductile. As a result of their resistance to corrosive chemicals and acids, such as hydrochloric acid, Hastelloy® alloys set them apart from other alloys. Also, an oxidizing agent resistant superalloy can be made by a metallurgist.

The Hastelloy metal consists of nickel, chromium, and molybdenum, as its constituent elements. Whereas Hastelloy metal has corrosion resistance, it also has high temperature resistance. Hastelloy metal is a nickel super-alloy with extremely high corrosion resistance. A wide range of applications for Hastelloy material are available in a variety of industries such as chemicals, petrochemicals, pharmaceuticals, and oil and gas. In this article, we will discuss the properties, applications, and grades of Hastelloy, c22 steel properties uns n06022, c22 material, hastelloy c22 composition, hastelloy c22 plate suppliers.

What is the composition of Hastelloy?

A Hastelloy alloy is a material produced by combining raw elements while they are in a hot liquid state. The average Hastelloy alloy consists of between 1% and 25% chrome, between 5% and 30% molybdenum, 0% and 30% iron, and a balance of nickel. There are also elements that can be added to the alloy, such as carbon, tungsten, vanadium, and titanium.

The Hastelloy alloy is a nickel-based alloy that shows excellent corrosion resistance. We call it a superalloy because it is able to withstand high temperatures, high stresses, and oxidizing environments. This alloy is available in a variety of forms, including plate, sheet, bar, pipe, and tube.

What Type Of Material Is Hastelloy?

The corrosion-resistant nickel alloy Hastelloy contains other chemical elements like chrome and molybdenum, as well as other corrosion-resistant elements. The oil and gas industry uses Hastelloy C276 as a grade for its exceptional corrosion resistance and high temperature resistance.

Hastelloy Alloy Types and Grades

The chemical composition of Hastelloy material determines its grade. Common Hastelloy grades include:

  • B-type Hastelloy materials
  • C-type Hastelloy materials
  • Hastelloy G-types
  • Hastelloy X, and
  • Hastelloy N

B-Type Alloys

B-type Hastelloy superalloys contain high percentages of nickel and molybdenum. They are known for withstanding extreme temperatures and reducing environments. The following materials are some of the B-type Hastelloy materials:

Alloy B-2 (UNS N10665): B-2 Hastelloy material contains 65% nickel and 30% molybdenum, as well as a small amount of carbon, iron, silicon, chromium, cobalt, manganese, sulfur, and nickel. A B-grade alloy is very corrosion resistant to hydrochloric acids, but it is not as corrosion resistant to oxidizing agents.

B-3 Alloys (UNS N10675):

 With 65% nickel and 30% molybdenum in its chemical composition and traces of chromium, cobalt, and manganese, this alloy provides excellent corrosion resistance and has superior thermal stability when compared to B-2 alloys. B-3 alloys have 65% nickel and 30% molybdenum in their chemical composition as compared to B-2 alloys.

C-Type Alloys

Nickel, chromium, and molybdenum make up a high percentage of this grade of Hastelloy. Chromium increases the resistance of Hastelloy metals to reducing environments and high temperatures. Hastelloy C grades can be used in both cold and hot environments. It is the most widely used Hastelloy metal type. Common C-type Hastelloy materials are:

C-4 Hastelloy (UNS N06455): 

In Type C-4 Hastelloy, 60% nickel is combined with 18% chromium, 16% molybdenum, 3% iron, 2% cobalt, and the rest is silicon, carbon, sulfur, titanium, etc. This alloy is highly ductile and corrosion resistant.

C-22 Hastelloy (UNS N06022): 

As the most widely used alloy for pharmaceutical reaction vessels and desulfurization systems worldwide, the Hastelloy C-22 consists of 58% nickel, 20% chromium, 13% molybdenum, 3.5% tungsten, 2.5% cobalt, and traces of other elements. C-22 Hastelloy is widely known for its weldability.

Hastelloy C-276 (UNS N10276):

 A grade of Hastelloy like this is often used in petrochemical industries, as it contains 59% nickel, 16% molybdenum, 15% chrome, 4% tungsten, and traces of other elements. There is a high level of corrosion resistance to oxidizing agents, pitting, stress corrosion cracking, and intergranular corrosion in this alloy.

C-2000 Hastelloy: 

In chemical process equipment applications, it is used for its excellent resistance to oxidizing media and for its use in chemical process equipment.

G-Type Alloys

It is suitable for welding using TIG, SAW, SMAW, and G-type Hastelloy materials as they contain tungsten as one of the alloying elements. The most important alloys in this group include:

Hastelloy G-3 (UNS N06985): The major components of this superalloy are nickel, chromium, tungsten, iron, molybdenum, and cobalt, which are the most well known.

G-30 Hastelloy (UNS N06030):The composition of nickel is 43%, the chromium is 30%, the iron is 15%, the cobalt is 5%, the tungsten is 4%, and manganese is 1.5%, with traces of other elements.

X-Type Alloys

Hastelloy X alloy (UNS N06002): Hastelloy X has high oxidation resistance, high-temperature strength, and SCC resistance as well as superior oxidation resistance. Chemically, Hastelloy X contains 44% Nickel, 23% Chromium, 20% Iron, 10% Molybdenum, 1% Manganese, and Silicon, plus traces of other elements. Cold-working and welding are both possible on this type of Hastelloy material. It is used for gas turbines, furnaces, and other industrial applications.

Hastelloy N (UNS N10003)

There are seventy-one percent nickel in Hastelloy N, 16 percent molybdenum, 7% chromium, 5 percent iron, and 1% silicon. Being oxidation resistant at higher temperatures, it is used in industrial applications such as chemical process equipment due to its high temperature oxidation resistance properties.
