High Temperature Environments
Find information to make an informed decision about which alloy to use in high temperature environments.
In the material selection process, many factors need to be considered including the temperature and environment.
Metals including: Nickel, Molybdenum, Dissimilar Metals, Embrittlement, Aluminum, Antimony, Cadmium, Bismuth, Calcium, Copper,
and more!
When Ni-20Cr alloys and stainless steels are oxidized while submerged in molten salt (NaCl or NaCl-KCl), readily oxidizable alloy components, such as chromium, and in some cases iron, migrate to the surface.
Nitriding is a similar process to carburizing. At elevated temperatures, a nitrogen rich (typically ammonia, NH3) gas is pumped into the furnace chamber.
Oxidation is the reaction of oxygen with an element in steel. The most common form of oxidation is rust. Rust itself is the build-up of thousands of molecules of iron oxide that form the reddish colored film on the surface of steels.
Corrosive Environments
Find information to make an informed decision about which alloy to use in corrosive environments.
Caustic soda (sodium hydroxide) is the most widely used and available alkaline material. Most caustic soda is produced as a co-product in the production of chlorine by the electrolysis of sodium chloride.
Ferric chloride is a strong oxidizer and is recognized for inducing pitting and crevice corrosion in stainless and nickel alloys. Solutions of ferric chloride have been used to evaluate the corrosion resistance of various alloys.
Hydrochloric acid (HCl) is a clear colorless liquid that is highly corrosive, and considered a strong mineral acid.
A chemical compound that contains fluorine. It can exist as a colorless gas or as a fuming liquid, or it can be dissolved in water
Corrosion affected by the presence of microorganisms in biofilms on the surface of the corroding material.
Nitric acid is the second largest commodity mineral acid, following behind sulfuric acid. It is a strong oxidizing acid and is used in CPI processes, the production of fertilizers and explosives.
Phosphoric acid is the third largest commodity mineral acid, following behind sulfuric and nitric. There are two basic routes to production – wet process and electric furnace process.
Sulfuric acid is the most widely used corrosive in the world and is generally considered to be the most important industrial chemical. The corrosivity of sulfuric acid on steel and nickel alloys can vary significantly.
