Chanchai Stainless, the Bangkok-based Thai company, is a prominent producer and distributor of high-grade stainless steel items for various industrial processes. Among its superior products, Stainless Steel 347 Fasteners are renowned for their superior strength, durability, and resistance to corrosion. Produced to function in tough environments, these fasteners offer consistency over a broad range of temperatures, allowing for reliable long-term service and stable operation. Resistant to harsh media such as acids, alkalis, and chlorides, Stainless Steel 347 Fasteners are relied upon for applications in chemical processing industries, marine engineering, aerospace industries, and power generation industries. Chanchai Stainless promises accuracy, quality, and customer satisfaction with each product.
Stainless Steel 347 Fasteners (UNS S34700) consist mostly of iron with 17–19% chromium, 9–13% nickel, and 10–12% niobium for stabilization. The addition of niobium provides intergranular corrosion resistance and avoids carbide precipitation during welding. These fasteners have superior oxidation resistance to 1000°C and work superbly under high-temperature conditions. They possess tensile strength of 515–700 MPa, yield strength of approximately 205 MPa, and elongation of 40%. They also have enhanced stress-cracking resistance, high durability, and good formability, which makes them extremely dependable for aggressive industrial conditions.
