The Importance of Avoiding Carbon and Stainless Cross

In various chemical applications,specific stainless steel grades will provide better corrosion resistance to certain chemicals than other steel grades.In those applications,contamination from carbon steel can negatively affect the structural integrity of the tank or vessel,resulting in a shorter life expectancy for that tank or ASME vessel.Testing the water tackling corrosion in pipework CIBSE The use of chemical inhibitors has its place,but should be considered a secondary line of defence,not a substitution for resolving oxygenation problems.An example of the corrosion of a steel pipe brought about by excessive dissolved oxygen (DO) can be seen in Figure 1.Steel - Testing of properties BritannicaSteel - Steel - Testing of properties The testing of steels properties often begins with checking hardness.This is measured by pressing a diamond pyramid or a hard steel ball into the steel at a specific load.The Vickers Diamond Pyramid Hardness tester,which measures the DPH mentioned above,uses an indenter with an included angle of 136 letters to the editorcarbon steel piping chemical#176; between opposite faces of a pyramid and
