Controlling Manganese Exposure The most common compounds in arc welding fume when welding on mild or carbon steel are complex oxides of iron, silicon and manganese, although many other compounds may also be in welding fume. Welders who are overexposed to substances in welding fume may potentially be at risk for various shortterm (acute) or longterm (chronic) health issues.

Manganese Statistics and Information Manganese (Mn) is essential to iron and steel production by virtue of its sulfurfixing, deoxidizing, and alloying properties. Steelmaking, including its ironmaking component, accounts for most domestic manganese demand, presently in the range of 85% to 90% of the total. Manganese ferroalloys, consisting of various grades of ferromanganese and silicomanganese, are used to
Low alloy steel in ASME Sep 18, 2010· Alloying elements are added to steel in various amounts and combinations (two, three, or more elements). Steel with up to percent total alloying elements is called lowalloy steel; with – percent, mediumalloy steel; with more than 10 percent, highalloy steel. Alloy steels are classified according to structure or use.
