add to cart The Nickel 200 Bolt represents a premium fastening solution manufactured from commercially pure nickel (≥99.6% Ni content). Produced to stringent standards including UNS N02200 and DIN W.Nr.2.4060, these bolts deliver exceptional performance across demanding industrial applications. With diameters ranging from 1/2 inch to 4 inches and lengths spanning 30 to 800 millimeters, the Nickel 200 Bolt accommodates diverse engineering requirements while maintaining hardness values between 45 and 80 HB. Manufacturing Excellence in has emerged as a strategic hub for specialty fastener production in China's southeastern coastal region. The city's advanced industrial infrastructure supports precision manufacturing of nickel-based fasteners, with local foundries employing vacuum melting techniques and cold heading processes specifically optimized for pure nickel materials. Manufacturers in benefit from proximity to major shipping ports, facilitating efficient global distribution of Nickel 200 bolts to markets across Southeast Asia, Europe, and North America. The region's cluster of metallurgical enterprises has developed particular expertise in processing high-purity nickel alloys, with quality control systems meeting ISO 9001 and ASTM international standards. This industrial ecosystem enables consistent production of Nickel 200 Bolts that satisfy the most rigorous customer specifications. Mechanical Performance Characteristics The Nickel 200 Bolt demonstrates remarkable mechanical properties across temperature ranges. At ambient conditions (20°C), tensile strength reaches 380 MPa with yield strength of 100 MPa. As temperatures elevate to 315°C, these values adjust to approximately 320 MPa and 80 MPa respectively, while at 400°C the bolt maintains 280 MPa tensile strength and 70 MPa yield strength. The material exhibits Vickers hardness decreasing from 100-120 HV at room temperature to 70-90 HV at 400°C, ensuring structural integrity in moderately elevated thermal environments. High-Temperature Endurance Creep resistance distinguishes the Nickel 200 Bolt for sustained high-temperature service. At 315°C under 50 MPa stress, creep rate measures approximately 1×10⁻⁸ per hour, increasing to 1×10⁻⁷ at 400°C. Oxidation resistance proves exceptional, with annual corrosion rates of merely 0.01 mm at 315°C and 0.05 mm at 400°C. The fatigue limit progresses from 200 MPa at room temperature to 150 MPa at 315°C, demonstrating reliable cyclic stress performance. Thermal expansion coefficients range from 13.3×10⁻⁶/°C (20-100°C) to 14.5×10⁻⁶/°C (20-400°C), while thermal conductivity decreases moderately from 90 W/(m·K) at 20°C to 75 W/(m·K) at 400°C. Application Environments The Nickel 200 Bolt excels in food processing equipment where sanitation and corrosion resistance are paramount. Salt extraction facilities rely on these fasteners for their resistance to chloride-induced corrosion. Mining operations, particularly marine mining applications, benefit from the bolt's durability in saline and abrasive conditions. Additional applications include caustic soda production, synthetic fiber manufacturing, and electronic component assemblies requiring low gas content and minimal vapor pressure. The bolt's high thermal and electrical conductivity further recommends it for heat exchanger systems and electrical grounding connections. Operational Recommendations For optimal service life, the Nickel 200 Bolt performs reliably at temperatures below 315°C. While capable of operation up to 400°C, users should consider accelerated creep and oxidation rates at higher temperatures. Avoid sulfide-rich environments above 300°C, as sulfur compounds can compromise nickel's corrosion resistance. Regular torque verification ensures maintained clamp load, particularly in cyclic thermal applications. Conclusion The Nickel 200 Bolt delivers proven reliability across corrosive and elevated-temperature environments. Backed by 's sophisticated manufacturing capabilities and strict quality protocols, these fasteners represent a cost-effective solution for industries demanding consistent performance. By minimizing maintenance requirements and extending equipment service intervals, the Nickel 200 Bolt demonstrates itself as an intelligent investment for critical industrial connections.
