Spring standard size stainless steel plate
We carry 631 and 316 from 0.05 to 2.0 mm in thickness!

In general, the number of businesses carrying SUS 631 and SUS 316 is limited due to the low amount in distribution, making either difficult to obtain. The number of businesses carrying thicknesses less than 0.1 mm and more than 1.0 mm is also small, thus acquiring such thicknesses can be time-consuming and laborious.

Eitai is a pioneer in spring stainless steel plate wholesale. We carry an abundant amount of SUS 631 and SUS 316 in intermediate thicknesses and can provide them as needed.
