What is Monel K-500 used for?

Monel™ K-500 (UNS N05500) is a nickel-copper alloy, age-hardened to achieve two to three times the strength of Monel 400. It retains these excellent mechanical properties up to about 650degC. It also exhibits excellent corrosion resistance in both chloride-containing and chemical environments. The combination of physical and mechanical properties means that it is widely used in a host of demanding applications.

What is austenitic stainless steel?

The most well-known grades of stainless steel are the austenitic stainless steel grades 304 and 316. An austenitic stainless steel is so-called because of the crystal structure the atoms take when the composition and thermal processing conditions allow. The austenite crystal structure is also described as face centred cubic (FCC) and defines many of the mechanical and physical properties of the stainless steel.

What is galling?

Galling is when two metal surfaces join unintentionally, caused by micro-welding across their surfaces at localised points of contact. This phenomenon is influenced by the surface condition (roughness), type of metal, environment, temperature and load exerted on the surface. Galling typically refers to the damage that occurs when breaking the items apart, with a tearing […]

What is Alloy 904L?

Alloy 904L is a more highly alloyed austenitic stainless steel, based upon 20% chromium and 25% nickel content. It was developed for use in applications containing dilute sulphuric acid. The substantial nickel content means that Alloy 904L is a lot more expensive than regular stainless steels. Therefore, it has seen some substitution from more cost-effective super duplex stainless steels (SDSS).

What is duplex steel?

A duplex steel is one that has a mixture of two different metallurgical phases within its microstructure. Although many different grades of steel possess two or more different phases, the term duplex is used almost exclusively for a family of stainless steels that combine austenitic and ferritic phases.
