Carbon steel powders and method of manufacturing powder metal components therefrom |
摘要 |
Fine powders of iron with less than 5% by weight graphite, copper, and an organic binder can be formed into shapes having a green density of up to about 7.4 g/cc and sintered in a hydrogen containing atmosphere to yield parts having minimum variations in physical properties. Incorporation of small quantities of copper, e.g. 1% or less by weight, negates variations in physical properties of sintered parts that were subjected to variations in the hydrogen content of the sintering atmosphere.
