The mechanical properties and The microstructure of structural low-all
oy nickel-molybdenum steel with various carbon contents were studied.
The specimens were produced from N2M powder partially alloyed with gra
phite by two methods: single compaction and sintering; and hot pressin
g of porous Stock. Heat-treated hot-pressed steel with a carbon conten
t of 0.4-0.7% has a breaking strength of 1300-1400 MPa, a bending stre
ngth of 2200-2300 MPa, and satisfactory ductility characteristics. The
materials developed are suitable for fabrication of powder-metallurgy
parts with enhanced physical and mechanical properties.
