A method for sintering a carbon steel part using a hydrocolloid binder as carbonsource.

摘要

The invention refers to a new method for preparing sintered structural parts of carbon or tool steels or high speed steel having a carbon content of up to 2% by weight, wherein an agglomerated spherical powder comprising at least 0.5% of a thermo-reversible hydrocolloid is pressed to a green body of high density which is then heated at 450-650° C. to remove the non-carbon content of the hydrocolloid and subsequently sintered at about 1100-1400° C. to structural parts having high strength properties.
