We at Chemipetro produce a wide range of pipes, flanges and pipe fittings in a range of materials such as duplex and super duplex stainless steels. We can also manufacture parts in specialist materials such as 6% Moly super austenitic stainless steels, or if you have a specialist application which may require something a little different to solve the problem, we can help to find the answer.

But what special qualities do these types of stainless steels have and why and where would you want to utilise them?

Molybdenum minerals have been on the market for a long time. Its name is derived from the ancient Greek word Molybdos meaning lead, with which its ores were confused for a long time. It was not until 1778 that a Swedish Chemist, Carl Wilhelm Scheele finally identified the mineral.

It has some unique properties in that it has the 6th highest melting point of any element and it readily forms hard stable carbides. When used as a component in stainless steels it produces a metal alloy which is very stable at high temperatures and is resistant to corrosive elements which would degrade other types of steel.

Another useful quality of this type of steel is its good weldability and resistance to hydrogen induce cold cracking and spot weld peeling. Other types of steels are not so easily welded and require the use of specialist welding techniques.

For this reason, it is particularly useful in applications such as equipment exposed to sea water, chemical processing and handling of materials that have high halide levels.
