Super Duplex Steel Washers are manufactured from a well-balanced proportion of austenitic and ferritic stainless steels, providing an excellent combination of mechanical strength and corrosion resistance. With very high tensile strength, superior hardness, and sound fatigue resistance, these washers are designed to perform under extreme conditions. They show performance in high and low temperatures and pitting, crevice corrosion, and stress corrosion cracking resistance, especially in chloride environments. Their enhanced strength-to-weight ratio makes them lighter in weight than regular stainless steel washers but retain high durability and consistent performance under high-pressure and corrosive conditions.
Super Duplex Steel Washers find applications in sectors where reliability, strength, and corrosion resistance are paramount. In chemical processing, they are resistant to harsh chemicals and harsh pressures. Their corrosion resistance by seawater is advantageous in marine use, extending the service life. In oil and gas applications, they ensure safe spacing and sealing at high stress. Power generation and construction industries also employ them extensively, where difficult operating conditions require high-quality washers. Their strength, durability, and corrosion resistance make them suitable for demanding and critical applications.
