Manganese Substitution Grades of Stainless Steel During World War II when nickel shortages were severe, the stainless steel industry turned to manganese as a substitute. Manganese is about half as effective in forming austenite as is nickel, so for every 1% reduction in nickel content, roughly 2% of manganese must be substituted.

tics. There are over 50 stainless steel grades that were originally recognized by the American Iron and Steel Institute (AISI) and are detailed in a designer handbook, Design Guidelines for the Selection and Use of Stainless Steel, available from the Specialty Steel Industry of North America (SSINA).
Manganese is a key component of lowcost stainless steel. Often ferromanganese (usually about 80% manganese) is the intermediate in modern processes. Small amounts of manganese improve the workability of steel at high temperatures by forming a highmelting sulfide and preventing the formation of a liquid iron sulfide at the grain boundaries. If ...
Controlling the phosphating process is essential to achieving consistent coatings which ultimately result in a stable powder coating process. The most important process controls in phosphate conversion coating are: Time – The longer the contact time, the more time to chemically react. The process must be long enough to allow the chemistry to ...

Steel Steel Wearresistant steels: Another group is the wearresistant steels, made into wear plates for rockprocessing machinery, crushers, and power shovels. These are austenitic steels that contain about percent carbon and 12 percent manganese. The latter element is a strong austenizer; that is, it keeps steel austenitic at room temperature.
