STEEL MATERIAL, STEEL MECHANICAL PART AND PREPARATION METHOD THEREOF, AND TERMINAL - A simplified explanation of the abstract

This abstract first appeared for US patent application 18447116 titled 'STEEL MATERIAL, STEEL MECHANICAL PART AND PREPARATION METHOD THEREOF, AND TERMINAL

Simplified Explanation

The patent application describes a steel material with specific components in certain mass percentages.

  • The steel material contains nickel, cobalt, molybdenum, rhenium and/or a rare earth element, manganese, silicon, carbon, oxygen, iron, and impurities.
  • The steel material is used to make a mechanical part.
  • The preparation method involves mixing alloy powder and a binder, performing injection molding, debinding and sintering, and heat treatment.
  • The end result is a steel mechanical part with desired properties.


Original Abstract Submitted

A steel material is disclosed. The steel material includes components in the following mass percentages: 14% to 20% of nickel, 7.5% to 11% of cobalt, 4% to 7% of molybdenum, to 0.5% of rhenium and/or a rare earth element, less than or equal to 0.2% of manganese, less than or equal to 0.2% of silicon, less than or equal to 0.1% of carbon, less than or equal to of oxygen, iron, and inevitable impurities. The steel mechanical part is made of the steel material. The preparation method includes: mixing alloy powder and a binder to prepare feed particles; performing injection molding on the feed particles to obtain an injection green billet of the steel mechanical part; performing debinding and sintering on the injection green billet in sequence to obtain a sintered blank; and performing heat treatment on the sintered blank to obtain the steel mechanical part.
