- *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.
- *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) |
