Today Kubota Corporation released the following statement regarding its steel plate inspection process. Kubota said that "We have learned of a number of inappropriate changes made to the inspection reports submitted to our steel plate customers, such as stating values different from those in the actual inspection, in rolling mill rolls which are metal consumable parts used in some of the production equipment for steel plates. It is most regrettable that such an incident has been discovered, and we sincerely apologize for causing concern and inconvenience to all our customers and concerned parties and commit to making changes that reduce the likelihood this misbehavior could continue."
An external law firm has begun a thorough investigation, and we will be reporting its findings as soon as we are able.
Outline of the product in question
(1) Product name: Rolling mill roll
(2) Composition of material: Alloy such as metal, nickel, chrome and molybdenum. The combination ratio is determined individually with each customer.
(3) Purpose: Used as consumable parts in some of the production equipment at steel plants, etc to process solid metal blanks into steel plates and shaped steel. “Rolling” refers to a metal processing technology where heated solid metal blanks are processed into thin, flat, steel plates and shaped steel by running it through two (or more), rotating, rolling mill rolls.
(4) Standards, etc.: There are no official standards that apply to the product in question; the specifications of the products are determined based on agreements with each customer. The inspection is conducted based on the determined specification, inside the company.
(5) Major customers: Steel manufacturers inside and outside Japan (99 companies) (Of this, 85 companies are confirmed to have purchased the product in question.)
(6) Sales (FY2017): Approx. 4.4 billion yen
(7) Production plant: Hanshin Plant, Amagasaki Office (64, Nishimukojima-cho, Amagasaki-shi, Hyogo prefecture)
Details of the inappropriate conduct (Facts that have come to light up to now with the internal investigation)
(1) Providing incorrect inspection results in report. It was confirmed that when reports were made on the “degree of hardness,” which determines the hardness of the surface of the product in question, and “the components’ combination ratio” deviates from those determined with the customer, the value written in the inspection results documentation was different from that of the actual inspection result.
(2) Attachment of metallographic structure micrograph that is different from the actual product which was shipped. It was confirmed that the metallographic structure micrograph associated with the inspection results report of the product in question was a recycled photo of a different product that met the requirements.
