Chanathip stands out as a top manufacturer and supplier of Super Duplex Steel Washers right in the heart of Bangkok, Thailand. We specialize in providing high-quality fastening solutions tailored for industries that demand exceptional strength and corrosion resistance. Super Duplex Steel boasts a unique blend of austenitic and ferritic phases, ensuring remarkable durability and resistance to stress corrosion cracking, pitting, and crevice corrosion, even in the toughest environments. At Chanathip, we offer a diverse range of washers, including plain, spring, lock, and flat types, all crafted to meet international standards. Our super duplex steel washers are extensively used in the oil & gas, marine, chemical, and power sectors, guaranteeing reliability, safety, and long-lasting performance.
Super Duplex Steel Washers are made up of 24–26% chromium, 6–8% nickel, 3–4% molybdenum, and nitrogen, with a hint of tungsten to boost resistance. This unique composition provides outstanding protection against chloride-induced stress corrosion cracking and harsh chemicals. Mechanically, these washers offer nearly double the tensile strength of standard stainless steel washers, along with excellent fatigue resistance and toughness at both low and high temperatures. Their ability to endure high pressure and corrosive environments makes them a dependable choice for critical applications. With superior hardness, stability, and a long service life, Super Duplex Steel Washers are perfect for demanding industrial operations.
