High Strength Stainless Steel Strips

Precision High Strength Parts NIPPON KINZOKU's hardened (i.e., high strength) steel strips are highly precise materials which can be applied to business machines, electric equipment and semiconductor components due based on our wealth of more than 30 years technical experience.

Product Information
● The thickness accuracy of micro-meter order is achieved.
● Excellent flatness is achieved by highly sophisticated rolling technology and high effective auto flatness control technology.
