Quality Assurance and Control

Quality assurance and control of stainless steel require extreme care. UEX has obtained ISO9001 certification for advanced quality assurance and control.

1. ISO9001

Our Isehara Steel Service Center obtained certification under ISO9002, an international quality control standard, in May 1998, through examination by the Japan Quality Assurance Organization.
The certification was subsequently updated to ISO9001:2000 in June 2003 and to ISO9001:2008 in 2009.
The Mishima Steel Service Center obtained ISO9001:2008 certification in January 2015. Both Centers updated their certification to ISO9001:2015 in November 2017.

2. Stencil Transfer Permission

Strict product control is implemented in the Isehara Steel Service Center, based on quality manuals and operation standards and under the instruction of suppliers. The Center has permission to make in-house stencil transfer (mark shift) from Nippon Steel & Sumikin Stainless Steel Corporation for stainless steel plates and similar permission from Nippon Steel & Sumitomo Metal Corporation for titanium plates. The Mishima Steel Service Center has permission from Daido Steel Co., Ltd to put a logo mark of the manufacturer on its round bar products.
