- *Steel between materials 1045 Carbon Steel and 1055 Carbon Steel may be used as an equivalent to 1049 Carbon Steel
- *Steel between materials 1045 Carbon Steel and 1049 Carbon Steel may be used as an equivalent to 1045 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.
- *Hard chrome plating for International Economy products is a mixture of flash plating and non-flash plating. In the case of non-flash plating, the film thickness is 5 to 10 μm.
- *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.
- *PPS (standard, natural color) does not contain glass fiber.
- *Please click here for the hardness after heat treatment and here for quality assurance.
- *The reference value for electrical resistivity for MC nylon (conductive) is 1-10² Ω・m and for MC nylon (antistatic) is 10⁴～10⁶ Ω・m.
- *Matte treatments will have either a chemical or blasting pre-treatment. The type cannot be specified. (If the type needs to be specified, please request a manual quotation.)
- *Nitriding treatment will be either, gas nitriding or salt bath nitrocarburizing. The type cannot be specified. (If the type needs to be specified, please request a manual quotation.)
- *Please refer to the table below for the surface hardness after nitriding treatment. (Hardness is for reference only and is not covered by quality assurance)
| Material | Reference hardness after nitriding |
|---|---|
| 1018 Carbon Steel | HRC38~44 (HV400~500) |
|
HRC33~49 (HV350~600) |
| 4140 Alloy Steel | HRC44~56 (HV500~800) |
| D2 tool steel | HRC59~66 (HV900~1300) |
- *Copper and brass are easily damaged due to their low hardness, and are prone to discoloration and rust due to moisture and handling. Please use caution when handling parts after delivery.
- *Copper and brass are currently only available for manual quotation.
