Osaka Riken Kogyo Co., Ltd. was founded in 1934 with rolling process business as a founding business.
We are specialized for changing the thickness of metal with rolling process technology and adjusting hardness with annealing heat treatment. In rolling process, we are mainly handling Special Steel, such as SK85, S60C, SKS51, etc., and Ordinary Steel, such as SPCC, to process based on customer required thickness with high precision. Also, we provide necessary hardness based on its thickness through annealing.
Those processed steels were using for automobile parts, cutlery, tools, under the various supply chain. We will keep continue to provide the highest quality product for the many industries.
It is to adjust the properties of metal by rolling process and heat treatment, and it makes to change tensile strength and hardness.
We process the materials and provide to meet customer needs which used as parts of everyday items.
We may not be able to accommodate certain conditions.
