    melting and refining process path reduces levels of tramp elements such as phosphorus and sulfur. A subsequent calcium treatment spheroidizes remaining manganese sulfides. The melt-and-refine approach optimizes strength and toughness properties in both the longitudinal and transverse directions of the final product.

  • Manganese Steel - West Yorkshire Steel

    Cutting and machining the steel by conventional methods is nigh on impossible, the best process for cutting is using plasma arc or laser cutting. In its supply condition high manganese steel has a hardness of approximately 200HB and an approximate tensile strength of 880 N/mm². This tough interior is maintained when the steel is work hardened.

  • Mangalloy - Wikipedia

    Material properties. Mangalloy is made by alloying steel, containing 0.8 to 1.25% carbon, with 11 to 15% manganese. Mangalloy is a unique non-magnetic steel with extreme anti-wear properties. The material is very resistant to abrasion and will achieve up to three times its surface hardness during conditions of impact, without any increase in brittleness which is usually associated with hardness.

Manganese made by the electrolytic process contains less than .03% impurities, while manganese made by other methods contains as high as 3% impurities.

  • Manganese Removal From The Drinking Water - Does the Be

    Manganese and iron removal can be achieved similarly by exchanging manganese and iron with sodium. Thereafter, the backwashing process can remove the metals from the softening filtering resin. The removal efficiencies of the water softeners vary depending on the pH level, iron concentration, and the water hardness.

    Aug 09, 2017 · Manganese. Manganese is frequently used in steels to help with the heat treating process. When steels are heated and quenched to increase hardness and strength, the quench must be done a fast rate. The faster this rate, the more unstable the process becomes. Manganese allows hardness and strength to increase the same amount but at a slower ...
