Introducing the characteristics and applications of lean duplex steel, general-purpose duplex steel, and super duplex steel!
We would like to introduce the "duplex stainless steel (SUS329J1 and others)" that we handle. "Lean duplex steel" is a low-cost type with low nickel content and minimal molybdenum, making it suitable for civil engineering, construction, industrial machinery, storage tanks, and more. In addition, we also handle "general-purpose duplex steel," which has excellent resistance to seawater corrosion, and "super duplex steel," which has corrosion resistance comparable to super austenitic steel. Our company supports you with a rich inventory of special steel (SC/SK/SUP/SCR/SCM) and stainless steel (SUS/HT1770), processing know-how, and material procurement both domestically and internationally (Japan/Thailand/China), as well as procurement of processed products. 【Characteristics】 ■ Lean duplex steel: A low-cost type with low nickel content and minimal molybdenum, beneficial for replacing SUS304 and SUS316 series with duplex steel. ■ General-purpose duplex steel: Excellent resistance to seawater corrosion. ■ Super duplex steel: Has corrosion resistance comparable to super austenitic steel. *For more details, please download the PDF or feel free to contact us.
