manganese brittleness

Steel Bessemer steel Britannica.com

He was also aware that manganese alleviated the brittleness induced by the presence of sulfur, but it was Robert Hadfield who developed (in 1882) a steel containing 12 to 14 percent manganese and 1 percent carbon that greatly improved wear resistance and was used for jaw crushers and railway crossover points.

Manganese: Nodules, Uses, Facts, Ore, Alloys, Metal

Manganese removes oxygen and sulfur when iron ore (an iron and oxygen compound) is converted into iron. It also is an essential alloy that helps convert iron into steel. As an alloy, it decreases the brittleness of steel and imparts strength. The amount of manganese used per ton of steel is rather small, ranging from 6 to 9 kilograms.

What is a Hot Shortness? Definition from Corrosionpedia

Hot shortness is caused by a lowmelting constituent, often present only in minute amounts, that is segregated at grain boundaries. The presence of iron sulfide causes problems in hot working, and this phenomenon is called hot shortness. Hot shortness is reduced by the addition of manganese, which combines with the sulfur to form manganese sulfide.
