STEEL F211 (9 S Mn 28)


This material is used in cylindrical and hexagonal nuts of standard steel for its machinability. On demand, it can also be used to manufacture spindles.

  • Tensile strength (N / mm2): 490-637.   
  • Elongation%: 7-13.
  • Brinell hardness HB kg / mm2: 135-175.

Properties: Easy mechanization.

Applications: Screws and bolts and in general mechanized parts in high performance automatic machines. The nuts manufactured in this material are not suitable for continuous motion transmissions (due to the phenomenon of seizure). The nuts made of steel are for manual fixing or positioning operations.
