NEUTRAL Hex Nut DIN2510NF M45 40CrMoV4-6

Generic High-Strength M45 Hex Nut Description This is a high-quality M45 hexagonal nut, manufactured in accordance with the German DIN 2510 NF standard. It is constructed from 40CrMoV4-6 (material number 1.7711), a high-strength, heat-resistant steel alloy, making it perfectly suited for demanding industrial applications involving high temperatures and pressures. The nut is finished with a yellow zinc passivated coating for superior corrosion resistance. Specifications Standard: DIN 2510 NF Thread Size: M45 Material: 40CrMoV4-6 (1.7711) Chrome-Moly-Vanadium Steel Coating: Yellow Zinc Passivated Application: High-pressure flange connections, turbines, pressure vessels Label Info Item Number: 100882 Description: HEX NUT 40CrMoV4-6 M45 DIN2510NF Application Designed specifically for use with stud bolts in flanged connections, as specified by DIN 2510. Common industries include power generation, oil and gas, chemical processing, and heavy engineering where joint integrity under extreme conditions is critical. CO2 Impact Choosing this surplus component prevents the manufacturing of a new one, saving an estimated 3.0 kg of CO2. This is comparable to the emissions from driving a car for 15 kilometers.

FAQ What is the significance of the material 40CrMoV4-6 (1.7711)?This is a high-strength, heat-treatable chromium-molybdenum-vanadium steel alloy. It’s specifically designed for components subjected to high temperatures (up to around 540 deg C) and high tensile stress, making it ideal for applications like steam turbines, pressure vessels, and chemical reactors. What is the correct tightening procedure or torque specification for a DIN 2510 M45 nut?The exact torque specification is not defined by the nut itself but by the application’s engineering requirements. It depends on the stud material, lubricant used (e.g., anti-seize compound), and the required preload for the gasketed joint. Always refer to the assembly documentation provided by the equipment manufacturer for the correct torque value and tightening sequence. Does the yellow zinc coating affect the nut’s performance or thread friction?Yes, the yellow zinc passivated coating primarily provides corrosion resistance. However, any coating will affect the coefficient of friction of the threads. This friction coefficient is a critical variable in torque calculations. It’s important to use the friction coefficient specified by the fastener manufacturer or the assembly designer, especially when using torque-based tightening methods. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
