The continuous casting process involves pouring molten metal through a die of the desired outside profile. If shaping on the I.D. is also desired, the material may flow around a mandrel to create that profile. As a result, continuous cast product is often chosen to dramatically reduce machining cost. Here are just two examples of…

There are numerous grades of austenitic stainless steel and obviously selection depends on more than one criterion. However, as these alloys are primarily used for corrosion resistance, the method most commonly used for initial selection and comparison is to establish PREn ratings (pitting resistant equivalent number). This is calculated using a simple equation to establish…
