Chanathip Nickel Alloys and Plates, located in Bangkok, Thailand, stands out as a leading manufacturer and supplier of top-quality Super Duplex Steel Bolts. These bolts are celebrated for their remarkable durability, strength, and ability to withstand tough environments, making them ideal for high-pressure and corrosive applications. Chanathip takes pride in ensuring that each bolt is crafted with precision, adhering to international quality standards for reliability and safety. Industries such as oil & gas, chemical, marine, and power generation trust their Super Duplex Steel Bolts, knowing they can handle extreme conditions without sacrificing performance.
These bolts are made up of approximately 24–26% chromium, 6–8% nickel, 3–5% molybdenum, and nitrogen, all of which work together to boost their resistance to pitting, crevice, and stress corrosion cracking. Their unique duplex microstructure, which combines ferrite and austenite, provides exceptional toughness, strength, and stability. On the mechanical side, these bolts can achieve a tensile strength of up to 800 MPa and a yield strength of around 550 MPa, along with impressive impact resistance. With their excellent hardness, fatigue resistance, and thermal stability, they are perfectly suited for critical environments that demand robust and long-lasting fastening solutions.
