S514 / S515

Aerospace Steel Sheet

S514 / S515 Aerospace Steel Sheet

BS S514 / BS S515 is a carbon-manganese steel available in sheet and strip.

Heat Treated Steel Sheet

Both grades chemically identical, BS S514 supplied heat treated to produce tensile strength (Rm) 770-1000 N/mm². BS S515 supplied soft annealed to give tensile strength (Rm) 460-600 N/mm² before final heat treatment.


BS S514 / BS S515 aerospace sheet is chemically identical. Where the alloys differ is in the way they are treated - BS S514 is supplied in the heat treated condition, whilst BS S515 is supplied in the soft annealed condition. The alloys are used when extra strength is required when compared with mild steel.

Typical Applications

Commercial applications for this engineering material include:

  • Wishbones
  • Space frame chassis
  • Aerospace fabrication
  • Bodywork
  • Blanking panels

We stock S514 / S515 in plate and sheet.
