Contributing to the SDGs! Offering proposals and cost performance with a rich variety of products.
From lean duplex to super duplex, leave your duplex stainless steel needs to Yamato Special Steel!
Duplex stainless steel is a type of stainless steel that combines austenitic and ferritic structures. By leveraging its high strength and high corrosion resistance, it allows for value engineering (VE) from general-purpose stainless steel and other materials, increasing options. We have a rich inventory of duplex stainless steel, ranging from lean duplex to super duplex. 【Characteristics】 ■ High strength: Weight reduction ■ High corrosion resistance: Resistance to stress corrosion cracking and pitting corrosion ■ Low thermal expansion: Reduced maintenance burden and extended lifespan ■ Resource-saving: Reduction of rare metals With a low nickel content, it is less susceptible to fluctuations in material prices, contributing to sustainable consumption and production patterns, which aligns with the SDGs. *For more details, please refer to the PDF document or feel free to contact us.
