Inventory & Product Information
We handle over 700 types of Cold drawn bars
Steel types: SS400*, S45C, SCM415, SCM435, SK4F-G, Free Cutting, KHCP (plated shaft), S45CHT
Shapes: Round bars, hexagonal bars, flat bars, square bars

Our SS400 polished steel bars are derived from materials such as SGD3, AISI1018, SWRM8-10, SGD1, SS400, etc., and do not correspond to the JIS standard SS400.
The tensile strength is equivalent to SGD400-D (however, there is no actual value).
Orderable from stock in Japan (planning to expand the stock variety)

KOHO Response: Priority on Speed for Rapid Response
KOHO's response time is one of the fastest in the industry, made possible by our extensive inventory. The basic delivery time is the next day, or the same day depending on the situation.
For pickups, we deliver the product "just in time." Orders can start from one standard length piece or one cut piece. We respond to quotations as quickly as possible. We can also accommodate products other than cold drawn bars

KOHO Quality: Products Based on Trust
By importing materials from Japanese manufacturers and keeping them in stock, we deliver the highest Japanese quality.
You will be satisfied with our dimensional tolerances, surface conditions, and the length tolerances of cut products.
For stocked items, it is possible to trace the history of all polished products from material to shipment.
Of course, this includes cut-off products that have already been shipped.
We can provide a mill sheet (component report).

KOHO Service: Providing Materials to Create Reliable Products
Small lots and small items of cut products are packed in bags to prevent loss and contamination.
We remove chips that tend to adhere to the cut products themselves and also remove large burrs.
Due to the increasing demand for cutting precision, we are transitioning from traditional band saw cutting machines to more precise carbide circular saw cutting machines, striving to minimize our customers' processing time.

We can provide various materials besides polished steel bars, including stainless steel, aluminum, and copper products, among others.
