Manganese Steel Castings By Ssrm Metal & Engineers

By keeping track with the market developments, we are eminent Manufacturer & Supplier of Manganese Steel Castings in Ahmedabad, Gujarat, India. It is only when the manganese content exceeds about 0.08% that the steel may be classed as an alloy steel. When manganese content exceeds about 10%, the steel will be austenitic after slow cooling. One particular type of steel, known as Hadfield manganese steel, usually contains 12% - 15% manganese.

Metallurgical Impect of Manganese on Steels Castings

Manganese is present in all steels as a de-oxidizer. Manganese reduces the tendency towards hot-shortness or popularly known as red-shortness resulting from the presence of sulphur, which enables the metal to be hot-worked. When manganese is absent or very low, the predominant sulphide in iron sulphide (FeS), which forms the eutectic with iron, has affinity to form thin continuous films around the primary crystals during solidification of the steel.
Manganese improves the strength properties of steel, while marginally impairing its elasticity. In addition, manganese has favourable influence on forging, welding and grain refining properties in steel castings. A higher content of manganese in the presence of carbon substantially increases the wear resistance. With up to 3% of manganese, the tensile strength of steels increases by about 10 kg/mm2 for every added percentage of manganese.
