Since it is our own stock, we can accommodate short delivery times and small lots! Excellent impact resistance with duplex stainless steel.
"UNS S31803/S32205" is a duplex stainless steel that is resistant to chlorides and sulfides, making it less prone to stress corrosion cracking. It has high mechanical strength, allowing for the design of smaller diameters for shafts and thinner plates, providing the advantage of weight reduction. Additionally, we also offer the super duplex stainless steel "UNS S32750," which has a pitting resistance equivalent number (PRE) value of 40 or higher. [Features] - Better thermal conductivity and less thermal expansion compared to austenitic stainless steels - Excellent impact resistance - Strong resistance to chlorides and sulfides, making it less likely to experience stress corrosion cracking - In-house stock allows for short lead times and small lot sizes *For more details, please refer to the catalog or feel free to contact us.

Company information
Seikyo Metal Co., Ltd. has earned the trust of our customers by focusing solely on the sale of special steel since our founding in 1924. Based on the knowledge and experience accumulated over this long period, we have been engaged in the "friction welding" business, a method of joining different metals, since 1980, and we have received high praise for contributing to cost reduction and material savings for our customers. Additionally, as this technology is suitable for the environment, we can expect further entry into new fields, and it is steadily becoming a major pillar of our company. Both the special steel sales business and the friction welding business are not merely profit-seeking ventures; we take pride in our work that benefits society through our customers, and we will continue to make relentless efforts moving forward.
