TOP TITANIUM MANUFACTURER-KOBELCO
Titanium Pioneer in Japan
Kobe Steel began research and development of titanium in 1949, and has since contributed to the growth of diversified industries for over 50 years.
Top Titanium Manufacturer in Japan
Cumulative production of titanium reached 100,000 tons in the 50 years since the start of production (as of 1999). This is the largest volume in Japan.
Unrivaled Integrated Titanium Manufacturer in Japan
The integrated production line from titanium melting to final products provides consistent quality design and quality control.
High Quality and High Reliability Proven by Many Authorizations as the Titanium Supplier for Aircraft Applications
Kobe Steel is authorized as the titanium supplier by aircraft and jet engine manufacturers both within Japan and abroad because of our highly-regarded forging technology, integrated manufacturing system, and supply record. In 2001, Kobe Steel became the first Japanese manufacturer to be authorized by Rolls-Royce plc as a supplier of compressor discs for their jet engines. We are one of just seven companies ever to have been authorized as suppliers of titanium and other materials.
World Acclaimed Production facilities
As a titanium pioneer, Kobe Steel has continued to produce high quality titanium products in our own Production facilities, best suited to titanium manufacturing.

Kobe Steel's purpose-built titanium production facilities include:
VAR furnaces, continuous annealing-pickling line, vacuum annealing furnace, tube welding line, ring rolling mill, etc.
Diversified Product Types
Production of various titanium materials from commercially pure titanium to titanium alloy corresponds flexibly to diversified product shapes, for example coils, sheets, plates, welded tubes and forgings.
Development of New Materials and New Technologies
Kobe Steel has successfully developed the materials, joining technology and functional surface treatment technology to meet any user needs.
