What is the relationship between Tokushu Kinzoku Excel Co., Ltd. and TOKKIN HOLDINGS Corp.?
Tokushu Kinzoku Excel Co., Ltd. is a 100％-owned subsidiary of Company TOKKIN HOLDINGS Corp.
On January 4, 2017, former Tokushu Kinzoku Excel Co., Ltd. changed its name to TOKKIN HOLDINGS Corp.
At the same time, the precision materials business division was spun off to establish new Tokushu Kinzoku Excel Co., Ltd.
New Tokushu Kinzoku Excel Co., Ltd. further enhance its expertise in the precision materials business, and as a global niche-top company that "makes your technology dreams come true",
we are committed to becoming a company that can continue for 100 years together with TOKKIN HOLDINGS Corp.
Could you ship overseas? Could you package the product for export?
Various Incoterms are supported.
Please contact our sales staff for detailed conditions.
We also offer packaging for export.
Could you ship samples directly overseas?
Yes, we can. We normally use courier services such as FedEx, so we can ship cut samples and small coil samples overseas.
(If the weight is large, it may be shipped by air.)
Please contact our sales staff first.
Depending on the recipient's account, we can handle cash on delivery.
What is "JIN"?
JIN is our original finishing name named after "JINSEI" means toughness in Japanese.
JIN refers to the thermal refining having world's highest strength and ductility, achieved by our unique processing conditions.
Currently, we can mass produce precipitation hardening stainless steel "TOKKIN 350" and stainless steel for springs "SUS301" is available.
If you need higher strength and ductility, we recommend TOKKIN 350 JIN.
For more information, please refer to this page.
We will be happy to make a proposal according to your needs, so please contact us if you have any questions. Contact Us.
Can you specify the weight of one coil?
The unit weight standard we can accept changes depends on the order lot.
Order lots and standard unit weights are as follows.
Lot → Standard millimeter unit weight (for coil weight, multiply millimeter unit weight by width)
300kg 0.5～1.5kg/mm
500kg 0.5～2.0kg/mm
1,000kg 1.0～3.0kg/mm
*Normally, smaller lots have smaller unit weights, while larger lots have larger unit weights.
Since there is balance of raw materials and product width, please contact us first if you have any requests.
What hardnesses can be handled for each steel grade?
The table for each steel grade is available at the following page.
Please check it.

Is it possible to paint OVIONE on molded parts?
Since the parts are passed through a continuous line, it is not possible to coat the molded parts.
However, by changing the post-coating to pre-coating material (OVIONE Coat), the manufacturing process can be shortened and the post-coating process can be reduced.
［Before] Material → Pressing → Post-coating → Productization
［After] Pre-coated material (OVIONE Coat)) → Pressing → Productization
Do you handle sheets?
Yes, we do.
We manufacture coiled materials and cut them flat by outsourcing processing before delivery.
Therefore, thickness and width are within our manufacturing range.
Please refer to the following for the manufacturing range.
Thickness: 0.010mm to 2.5mm
Width: 300 mm or less
Length: 2,000 mm or less
Some dimensions cannot be manufactured depending on the balance of thickness, width, and length,
so please contact us for details.
