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 1045 Carbon Steel and 1055 Carbon Steel may be used as an equivalent to 1049 Carbon Steel
  • *1018 Carbon Steel (polished) and 1045 Carbon Steel (polished) are not compatible with trivalent chromate.
  • *1018 Carbon Steel (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.
  • *1049 Carbon Steel or Equivalent (tempered material) has a hardness of 20 to 34 HRC. Hardness 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 6063 Aluminum Alloy.
  • *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)
  • *The thickness of Clear Hard Anodizing is approximately 10 to 30 μm. The color will vary depending on the thickness of the coating.
  • *Phosphate Coating surface treatment will be either zinc phosphate or manganese phosphate. The type cannot be selected and the color and other characteristics vary for each.
