Sulfuric Acid: Which Fastener Material is Best?
Sulfuric Acid ( H2SO4 ) is one of the most widely used and important acids, being an essential component to many industries. Equally as important is selecting the right material to survive this environment. This newsletter will provide options.
Picking the Right Materials for Desalination
Desalination is an important emerging process to bring fresh water to more and more parts of the world. As new processes emerge, we get the opportunity to explore newer and less corrosion-prone materials, meaning that desalination units last longer and work better....
Heat Treatments for Austenitic Stainless Steels
Introduction Unlike martensitic steels, the austenitic stainless steels are not hardenable by heat treatment as no phase changes occur on heating or cooling. Softening is done by heating in the 1050/ 11200°C range, ideally followed by rapid cooling. This is of course...
Selecting welding consumables for stainless steels
Matching the consumables to the parent material The composition of stainless steel welding consumables is matched with the base or parent material. The chemical analyses (composition) of the consumables used are usually balanced to optimise the welding process and...

Pitting and Crevice Corrosion – Offshore
Pitting and Crevice Corrosion of Offshore Stainless Steel Tubing Oil and gas platforms regularly use stainless steel tubing in process instrumentation and sensing, as well as in chemical inhibition, hydraulic lines, impulse lines, and utility applications, over a wide...
Chloride Stress Corrosion Cracking & Relative resistance of Various Stainless Steel Grades
CORROSION: Chloride Stress Corrosion Cracking Definition: The combination of tensile stress and a specific corrosive environment can crack stainless steels. This mode of attack is termed stress corrosion cracking (SCC). The most common environmental exposure...

An Understanding for Pressure Class for Flanges
Pressure Temperature Rating (PT-Rating) All Pipes and various pipe fittings are most commonly classified based on their pressure temperature rating or commonly known as P-T Rating. The most common way of specifying pipe pressure temperature rating is given by ASME...
