add to cart ASTM B637 Bolt Overview The ASTM B637 Bolt is a high-performance fastener that complies with ANSI standards, manufactured from ASTM B637 UNS N07718 material. It is specifically designed for industrial applications that require corrosion resistance and high strength. This M16 specification bolt has an overall length of 100mm and comes with two heavy-duty hex nuts, making it suitable for various harsh conditions. Material Analysis of ASTM B637 UNS N07718 ASTM B637 UNS N07718 is a nickel-based alloy used in demanding industrial environments, particularly where high temperatures, high pressures, and corrosive media are involved. This material primarily consists of nickel (approximately 50%), chromium (13%), with small amounts of molybdenum (3%) and aluminum (1%). Its chemical composition provides excellent oxidative resistance and local corrosion resistance in highly corrosive environments. In terms of mechanical properties, ASTM B637 UNS N07718 has a tensile strength of about 1,240 MPa at room temperature, with a yield strength typically above 700 MPa. Its high toughness makes it resistant to fracture when subjected to impact. Furthermore, the material exhibits good ductility, with an elongation rate of up to 30%, facilitating the satisfaction of complex structural requirements during molding and processing. At elevated temperatures, N07718 retains good performance, with a working temperature reaching up to 700°C, making it suitable for critical component manufacturing in aerospace, petrochemical, and nuclear industries. In terms of corrosion resistance, N07718 performs excellently against acidic and alkaline environments, as well as sulfides and chlorides. With its outstanding mechanical and corrosion-resistant properties, ASTM B637 UNS N07718 has become an indispensable material choice in high-demand industries, particularly in environments exposed to extreme temperatures and corrosive media. Compared to stainless steel grades 304 and 316, UNS N07718 exhibits superior oxidation and stress corrosion resistance in chloride environments. Additionally, its high strength enables reduced structural design size and weight under equivalent conditions. However, it is essential to note that the cost of N07718 is higher, as the market price typically exceeds that of conventional stainless steel. Moreover, N07718 presents certain challenges in welding and machinability, requiring specialized welding materials and processes to ensure joint strength. The brittleness of this material at low temperatures may impact its applicability in specific environments. Overall, although UNS N07718 provides exceptional performance, it is crucial to weigh its cost and processing difficulty in application.
