Corrosion Resistant Alloys
As the markets needs grow more sophisticated, the demand for development of new products is rising.
On the other hand, it is now a prime task for manufacturers to improve productivity and to reduce investment and maintenance costs. Consequently, demands for corrosion-resistant alloys are growing due to the following needs: improvement in product reliability; consistency in equipments for new processes; optimization of repair and maintenance processes; reduction of equipment maintenance frequency span; reduction of total investment costs by taking into consideration of running and maintenance costs, etc.
Based on accumulated during over 40 years technological experience in melting, processing, quality control and corrosion-resistance in various industries, Proterial, Ltd. Okegawa Works manufactures various corrosion-resistant alloys and also offers related consulting services.
The following list, for reference, is a comprehensive introduction to the various types of alloys. Please note that the values presented are average and are not guaranteed.
