Material, Surface Treatment and Hanging Holes

  • The following materials and surface treatments are possible.
  • *Depending on shape and size, hanging holes may be necessary for surface treatment. Refer to the Design Guidelines for information on hanging holes.

  • *Steel between materials EN 1.1191 equiv and EN 1.1203 equiv may be used as an equivalent to EN 1.1206 equiv.
  • *EN 1.0038 equiv.(flat bar) and EN 1.1191 equiv.(flat bar) are not compatible with trivalent chromate.
  • *EN 1.0038 equiv.(annealed material) is not compatible with trivalent chromate (black) or hard chrome plating.
  • *The film thickness of hard chrome plating (flash plating) is less than 5μ. The hardness (Vickers) is about Hv750~, and it is difficult get the plating on holes and pockets.
  • *The value of EN 1.1206 equiv.(Reference Hardness: 20-27HRC) cannot be guaranteed and cannot be specified.
  • *Pre-hardened steel between 37 and 43 HRC may be used as an equivalent to NAK55.
  • *Black anodize (matte) is not applicable for EN AW-6063 equiv.(flat bar).
  • *Thin plate standards (thickness 3㎜≤Z<5㎜）are not applicable for surface treatment.
  • *Not required for anodized aluminum if the displayed agreement is agreed to.
  • (However, a wire mark may be left)
