Description and application

Carbon

Carbon steel and stainless steel are both metals used in a wide range of commercial and consumer applications. The main difference between the two is the components that are added to the steel to make it useful for the desired purpose.

Super Duplex

Super Duplex is generally more complex, more high alloyed materials with PRET (Pitting Resistance Equivalent Number) = 40.0, providing even higher strength and corrosion resistance, making them suitable for highly demanding applications for example offshore marine engineering.

Hastelloy

Hastelloy is uniqely resistant agianst highly oxidizing and reducing agents, making it a good choice in moderate to severe corrosive environments. It is commonly used for pipes and valves in chemical processing and petrochemical industries. It is also used in nuclear reactors and chemical reactors, and is excellent for pressure vessels and heat exchangers.

Incoloy

Incoloys high temperature strength and resistance to sea water, saltwater, high sulfur and chlorine gases makes it ideal for use in the oil and gas industry. It is also used for propeller shafts, chemical equipment, gas turbines, aircrafts and tankers. Alloy Incoloy can with other elements, further increase the resistance to chemically corrosive environments such as sulfuric acid and phosphoric acid.

Inconel

Inconel alloys are oxidation and corrosion resistant materials that are suitable in extreme environments with pressure and heat. When heated, Inconel forms a thick, stable passive oxide layer that protects the surface from further attacks. Inconel retains its power over a wide temperature range, attractive for high temperature applications where aluminum and steel will be divided due to thermally induced crystal.

Monel

Monel is a group of nickel alloys, primarily composed of nickel and copper with small amounts of iron, manganese, carbon and silicon. Stronger than pure nickel. Monel alloys are resistant to corrosion of many substances, including fast-flowing seawater. They can be easily manufactured by hot and cold processing and welding.

Non ferrous

In metallurgy, non ferrous metal is a metal, including alloys that do not contain iron (ferrite) in noticeable amounts. Generally more expensive than ferrous metals. Non ferrous metals are used because of desirable properties such as low weight (eg aluminum), higher conductivity (eg copper). Non-ferrous metals can be categorized into aluminum, copper, brass, silver and lead.

Stainless

Stainless steel is resistant to rust. In a more technical sense; in order for the steel to be defined as stainless, the steel must have a minimum content of chromium, and thus the steel is resistant to corrosion. However, in relation to corrosion, pay attention to oxygen and sea water.

Titanium

Titanium is a light, strong metal with a natural resistance to sea and chlorine corrosion. It has the highest strength of all steel types in relation to the weight of the metal, and even in its unalloyed form it is very strong, but about 45% lighter than other steel types.
