Hastelloy C22 Hastelloy C276 6 inch welded stainless steel pipe fittings factory

1. Introduction

• Hastelloy C22 (N06022) is made of nickel, molybdenum, cobalt,

Tungsten and other elements, containing about 60% nickel. It is an all-round nickel-chromium-molybdenum tungsten

The alloy has better overall corrosion resistance than other existing nickel-chromium-molybdenum alloys, including Hastelloy

C-276, C4 alloy and 625 alloy. Hastelloy C22 alloy has good resistance to pitting corrosion, crack corrosion and stress

Corrosion cracking. It has excellent antioxidant capacity in aqueous media, including wet chlorine, nitric acid,

or a mixed acid of an oxidizing acid containing chloride ions.

• At the same time, Hastelloy C22 (N06022) hardener alloy also has the ability to reduce and oxidize the environment

Encountered in the course of ideal resistance. With this versatile feature, it can be used for many

Troublesome environments, or in multiple production plants. Hastelloy C22 (N06022) alloy has abnormalities

Resistant to a wide range of chemical environments, including strong oxidizing substances such as ferric chloride,

Copper chloride, chlorine and heat pollution dissolved. Liquids (organic and inorganic), formic acid, acetic acid,

Acetic anhydride, seawater and salt solutions. Hastelloy C22 (N06022) alloy is resistant

Grain boundary precipitation is formed in the heat-affected zone of the weld to enable it to adapt

Many chemical processes are in a welded state.

5. Character

Hastelloy C22 alloy is a versatile nickel-chromium-molybdenum tungsten alloy with a better whole

Corrosion resistance superior to other existing nickel-chromium-molybdenum alloys, including Hastelloy C276,

C4 alloy and 625 alloy. Hastelloy C22 alloy has good resistance to pitting corrosion, crack corrosion and stress

Corrosion cracking. It has excellent antioxidant capacity in aqueous media, including wet chlorine, nitric acid,

or a mixed acid of an oxidizing acid containing chloride ions. At the same time, Hastelloy C22 alloy also has:

The ability to reduce and oxidize the environment encountered in ideal resistance processes. With this

Versatile, can be used in multiple troublesome environments, or multiple productions

Plant. Hastelloy C22 alloy is exceptionally resistant to a variety of chemical environments, including strong

Oxidizing substances such as ferric chloride, copper chloride, chlorine, thermal pollution solutions (organic matter,

inorganic), formic acid, acetic acid, acetic anhydride, water and salt solutions, etc. Hastelloy C22 alloy has:

the ability to resist the formation of grain boundary precipitation in the welding heat-affected zone,

Therefore, it can adapt to many chemical processes in the welding state.
