titanium would be costly

Dear Friend,

Stainless steels are the most widely used material in desalination plants. The ideal material for use in desalination plants is titanium because it suffers little to no corrosion in saltwater environments. However, titanium is far more expensive than stainless steels. There are advancements being made to improve the corrosion resistance of stainless steels. Highly alloyed ferritic and austenitic stainless steels are being tested in salt water in comparison to titanium. The stainless steels are normally alloyed with chromium, nickel, molybdenum, and nitrogen to improve their corrosion resistance.

Subject: [MW:29899] Material selection for Desalination plants and brinesolution

Dear expert,

Which material is suited to desalination plants keeping in mind the corrosion resistant properties?

Will titanium work well?

If any references or process licensors data available specifically for these applications do share.

Regards,

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

Introduction The colour formed when stainless steel is heated, either in a furnace application or in the heat affected zone of welds, is dependent on several factors that are related to the oxidation resistance of the steel. The heat tint or temper colour formed is caused by the progressive thickening of the surface oxide layer and so, as temperature is increased, the colours change. Oxidation resistance of stainless steels However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. The colours formed can only be used as an indication of the temperature to which the steel has been heated. Factors affecting the heat tint colours formed Steel composition The chromium content is the most important single factor affecting oxidation resistance. The higher the chromium, the more heat resistant the steel and so the development of the heat tint colou...

The Schaeffler and Delong diagrams for predicting ferrite levels in austenitic stainless steel welds

Introduction Ferrite is important in avoiding hot cracking in during cooling from welding of austenitic stainless steels. 'Constitution diagrams' are used to predict ferrite levels from the composition by comparing the effects of austenite and ferrite stabilising elements. The Schaeffler and Delong diagrams are the original methods of predicting the phase balances in austenitic stainless steel welds. Nickel and chromium equivalents A 'nickel equivalent' is calculated for the austenite stabilising elements and a 'chromium equivalent' ferrite stabilising elements. These are used as the axes for the diagrams, which show the compositional equivalent areas where the phases austenite, ferrite, martensite (and mixtures of these) should be present. Although intended to show the phase balance of weld fillers, these diagrams can also be used to illustrate the phase balance of the 'parent' material. There are different diagrams for dif...
