Quality Management

By challenging the limits of technology, we continually deliver stainless steel and high-performance alloys that genuinely satisfy our customers.
We have made it our mission to help build a creative society through our products. To this end, we are endeavoring to boost our product quality even further by establishing and standardizing production technologies and verification technologies that address the needs of our customers.
One result of our dedication has been the recognition of our robust quality assurance system, evidenced by our JIS certification, ISO 9001, and certifications from other classification organizations for the Kawasaki Plant and our production base as well as certification (Pressure Equipment Directive (PED) AD-2000) of our materials for used in pressure vessels.
