Stainless Steel Spinning Superhero
Stainless steel sometimes reminds me of a superhero. It is versatile and does not stain, corrode or rust very easily. Superheros are versatile and have alter egos and lives (Spiderman is Peter Parker, a newspaper photographer, and Superman is Clark Kent, a newspaper reporter), yet they are strong and do not break down easily. For this reason, stainless steel is often used in industrial processes.
Stainless steel was invented by English metallurgist Harry Brearley in order to protect cannon bores from erosion in the early 1900s. Today it is used for many different applications in many industries including architectural, aviation, industrial, automotive and manufacturing, just to name a few. It is used in a cold metalworking process called metal spinning. This process takes steel disks that are mounted on lathe mandrels and rotated at high speeds and shaped by tools called spoons and applies it to the stainless steel surface as it spins. This allows the metal spinner professional to shape axially symmetric metal parts.
A variety of versatile stainless steel products and parts can be created through a spinning process. These products and parts have high strength, performance and hardness. An unseen layer of protection is created with stainless steel’s chromium content. This protects against scratches and oxidization of steel. Even with exposure to harsh industrial and external applications, products made with stainless steel spinning can retain their sheen.
Bowls, tank heads, architectural lighting, finials and other products are examples of products with spun steel metal parts. The cold working process used in metal spinning is done at room temperature. Other metalworking processes include heat, also known as hot working processes. Parts and products made of stainless steel spun parts can be made to order. One can utilize manual metal spinning in which a seasoned metal spinner technician must run the machine or the process can be automated with the use of CNC machining.
