Notes

  • The main steel grades are given for reference only.Ferritic-austenitic (duplex) grades are outside the scope of JIS B 1054.
  • The martensitic grades (C1, C3, C4) and the ferritic grade (F1) have different upper limits on nominal diameter.F1 goes up to 24 mm, austenitic grades up to 39 mm.
